Imager release history. Older releases can be found in Changes.old - when drawing on an image with an alpha channel where the source minimum is greater than zero, Imager would read from beyond the end of a malloc() allocated buffer. In rare circumstances this could lead to some of the source image not being written to the target image, or possibly to a segmentation fault. I don't believe this has any security concerns beyond that. - if the first text drawn with Imager::Font::T1 is not anti-aliased, text drawn would be nonsense. This would also read beyond the end of a malloced buffer. - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be truncated early. https://rt.cpan.org/Ticket/Display.html?id=88993 Imager 0.97 - 15 Jul 2013 =========== No changes from 0.96_02. Imager 0.96_02 - 8 Jul 2013 ============== - PNG: treat a version mismatch between headers and library as a probe failure. https://rt.cpan.org/Ticket/Display.html?id=86659 - PNG: the check for benign error support is more complex than a simple library version check, check for the appropriate macro. Thanks for Slaven Rezic for following up on my CPAN Testers result queries. https://rt.cpan.org/Ticket/Display.html?id=86659 - W32: add a missing head1 AUTHORS to the old Win32.pm https://rt.cpan.org/Ticket/Display.html?id=86658 Imager 0.96_01 - 1 Jul 2013 ============== - TIFF: handle SampleFormat = 2 by translating the signed integer values to unsigned by flipping their sign bits. Handle SampleFormat = 3 where possible. SampleFormat is ignored for paletted images. Mixed SampleFormat are handled incorrectly, since libtiff returns only the first SampleFormat value, and an image with both an alpha channel and SampleFormat = 2 for color channels probably has a different SampleFormat for the alpha channel. https://rt.cpan.org/Ticket/Display.html?id=74540 - XS clean up: https://rt.cpan.org/Ticket/Display.html?id=69243 - Imager::Color's rgba() method now returns its values as integers instead of floating point. (IV instead of NV). - The XS for i_map() and i_matrix_transform() now use the AV * typemap instead of rolling their own. - The XS for DSO_call() now uses the HV * typemap instead of rolling it's own. - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and i_gradgen() now use a new T_AVARRAY typemap that greatly simplifies the XS code. - many other minor XS changes - some XS code formatting - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering now renders in alpha-combining mode, to match antialiased output. https://rt.cpan.org/Ticket/Display.html?id=73359 - add sample code and cookbook notes for drawing a blurred drop-shadow. - add support for libpng 1.6, which changed the defaults for reporting some types of error. https://rt.cpan.org/Ticket/Display.html?id=85746 - FT2: use gsamp/psamp() to transfer pixels from the work image to the output image instead of gpix/ppix. https://rt.cpan.org/Ticket/Display.html?id=83478 - eliminate various GCC warnings, mostly initialized but otherwise unused variables. Imager 0.96 - 19 May 2013 =========== - rearrange Imager's test files. https://rt.cpan.org/Ticket/Display.html?id=84596 - Imager::Probe::_gcc_lib_paths now forces C locale. A sufficiently recent gcc prints localized keys for the search paths, which avoids that localization. https://rt.cpan.org/Ticket/Display.html?id=84963 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set and true. https://rt.cpan.org/Ticket/Display.html?id=85262 reported by Andreas König - add a test for unclosed POD in C source, and fix the errors it found. https://rt.cpan.org/Ticket/Display.html?id=74875 - fix some spelling errors detected by the newer aspell in Debian Wheezy. - remove a trailing ' from lib/Imager/Font/Test.pm's POD thanks to gregor herrmann https://rt.cpan.org/Ticket/Display.html?id=85413 - add a test for standard =head1 commands and fix the errors found Imager 0.95 - 19 Apr 2013 =========== - handle the SVf_UTF8 flag correctly on magic strings passed to Imager::IO's write() and raw_write() methods. This may misbehave in perl 5.6.x since the UTF8 flag may not be visible in the main SV after SvGETMAGIC(). https://rt.cpan.org/Ticket/Display.html?id=83438 - document that bounding_box() ignores the transformation matrix supplied to tranform() for fonts. https://rt.cpan.org/Ticket/Display.html?id=84106 Imager 0.94_02 - 5 Apr 2013 ============== - enable debug logging for the standard font tests - skip the overloaded UTF-8 text output checks on 5.6.x and earlier, due to a bug in that version of perl. - don't test for read() failing on a write-only handle in 5.8.x and earlier, this was fixed in change 862083f7e4 in perl. - report the version of Inline found during testing (an attempt to diagnose some intermittent failures.) Imager 0.94_01 - 2 Mar 2013 ============== - NOTE: possibly backward incompatible: support reading from/writing to perl filehandes that aren't raw files. This allows Imager's I/O to honour handles with layers such as gzip, scalar file handles or tied file handles. This is backward incompatible in that previous Imager would simply use fileno() to retrieve the fd for the file and call write(2) etc on it directly. https://rt.cpan.org/Ticket/Display.html?id=78843 - moved most of README to lib/Imager/Install.pod which should make it more accessible to the "web" generation, also significantly updated and re-worked it. - updated README's for the separately distributed modules to refer to Imager::Install, and that they need -dev versions of packages https://rt.cpan.org/Ticket/Display.html?id=81265 - the JPEG test code now reports the compile-time library version - avoid a possible compiler optimization issue on CentOS 5.9 i386 by rearranging (and mildly optimizing) some code. https://rt.cpan.org/Ticket/Display.html?id=83212 - fix a POD error in Imager::Fill (detected on new Pod-Simple) https://rt.cpan.org/Ticket/Display.html?id=83434 - fix a broken link to Graphics::Magick https://rt.cpan.org/Ticket/Display.html?id=82743 - drawing text to a channel with FT2 would draw with random coverage due to an uninitialized alpha channel. - marked the function pointer underlying the mm_log() API with the correct gcc magic and fixed the resulting warnings. - fixed some other compiler warnings - Imager::Font::W32 now properly reports text drawing errors https://rt.cpan.org/Ticket/Display.html?id=70098 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded) strings passed as text to draw(), bounding_box(), has_chars(), glyph_names() (where supported) in each of the font drivers. This may misbehave in perl 5.6.x since the UTF8 flag may not be visible in the main SV after SvGETMAGIC(). https://rt.cpan.org/Ticket/Display.html?id=83438 (partial) Imager 0.94 - 15 Dec 2012 ========================= Variations on some of these changes were included in development releases. - improved thread safety - the internal error stack and log file handle are now in a per-thread context object - JPEG now captures IPTC information in a thread-safe way - avoid globals where possible for warning capture in libtiff - use a mutex to avoid re-entering thread-unsafe giflib - use a mutex to avoid re-entering thread-unsafe tifflib - use a mutex to avoid re-entering thread-unsafe T1Lib - use a library handle per thread for freetype 2. - use an engine handle per thread for freetype 1.x. - originally these changes broke ABI compatibility, this has been restored. - clarify the return value of getpixel(); https://rt.cpan.org/Ticket/Display.html?id=81198 - fixed a race condition in parallel testing for T1 - fixed a bug in handling yoff for untransformed image-based fills - documentation improvements for Imager::Fill - FT2: report the library version while testing. Imager 0.93 - 15 Oct 2012 =========== Bug fixes: - previously a transparency enabled GIF write (the default) would always use a GIF89a header even if none of the images were transparent. - previously the probe step for freetype-config would fail on cygwin - catch an invalid matrix parameter to convert() instead of crashing https://rt.cpan.org/Ticket/Display.html?id=79922 - remove the 16-bit/sample limitation from the documentation for setsamples(), it hasn't applied for many releases. https://rt.cpan.org/Ticket/Display.html?id=79989 - don't copy setsamples() data parameter, it may be a large scalar https://rt.cpan.org/Ticket/Display.html?id=79990 - clean up .dSYM directories generated performing probes on OS X Mountain Lion. - pass the --verbose command-line option through to Imager::Probe in sub-module's Makefile.PLs https://rt.cpan.org/Ticket/Display.html?id=75878 Enhancements: - support for giflib 5.0. (5.0.1 and later) https://rt.cpan.org/Ticket/Display.html?id=79029 The giflib API Imager uses doesn't have a mechanism to set the header version in 5.0.0. - update the GIF library probe code to check for the new giflib 5.0.1 EGifSetGifVersion() function, and to check for the giflib 4.2.0 uninitialized gif89 bug. https://rt.cpan.org/Ticket/Display.html?id=79679 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304 - avoid static variables when capturing IPTC data from JPEG files - match Imager::Font;:T1's error message translations to those from later versions of T1Lib. - for libtiff versions that support extended warning handlers (3.8.0 or later), use them to avoid some global variables. - note Image::ExifTool for better metadata support. https://rt.cpan.org/Ticket/Display.html?id=79251 Imager 0.92 - 14 Aug 2012 =========== - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that correctly for both probing and runtime. https://rt.cpan.org/Ticket/Display.html?id=77672 - allow building JPEG/imexif.c on C89 compilers. - allow building GIF/imgif.c on C89 compilers. Imager 0.91 - 4 Jun 2012 =========== Bug fixes: - The size of rotated images is no longer rounded up so aggressively. Added rounding to the linear interpolation done for rotate() and matrix_transform() for 1 and 3 channel 8-bit images. Adjusted the two tranlate matrices used to build the final rotation matrix to use the distance between the outlier pixels rather than the pixel dimensions (ie. dimension-1). With all of this the output of rotate(degrees => 270) on an 8-bit image exactly matches the output of rotate(right => 270). https://rt.cpan.org/Ticket/Display.html?id=77063 Other changes: - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's internals, those names only matter for the XS interface. - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds the API level compiled into a loadable module such as Imager::File::GIF doesn't match that of Imager. Previously it could be difficult to determine exactly which module was failing to load. https://rt.cpan.org/Ticket/Display.html?id=77173 - added Imager->check_file_limits() as an interface to the i_int_check_image_file_limits() API. - Imager->set_file_limits(reset => 1) now resets the limits to the defaults rather than setting them all to unlimited. - wrote a brief security note as Imager::Security https://rt.cpan.org/Ticket/Display.html?id=68910 Imager 0.90 - 30 Apr 2012 =========== Bug fixes: - Imager::Test::is_imaged() attempted to process an "epsilon" parameter but the prototype didn't allow for the extra parameter. Corrected the prototype. - when downconverting samples (eg. from floating point to 8 bit) Imager now rounds the sample value rather than attempting to allocate input values over output values equally. The old behaviour had the probably surprising effect of converting a floating point 2.1/255.0 into an 8-bit 3 rather than the expected 2. This may result in slightly different 8 or 16-bit output images. - BI_BITFIELD BMP images were handled incorrectly, both in incorrectly calculating the space required for the masks and in processing the image data itself. https://rt.cpan.org/Ticket/Display.html?id=76736 - some odd width BMP BI_RLE4 images use run lengths that run one off the edge of the image. Imager now allows this, discarding the extra column. - odd length RLE4 runs in BMP images were decoded incorrectly. - pkg-config could sometimes return a library that was in a directory EU::MM / $Config{libpth} doesn't know about, but the compiler did. If no -L is included in the pkg-config library information check if EU::MM can find the library, and if not, search our configured directories and insert that into the library flags. https://rt.cpan.org/Ticket/Display.html?id=75869 - Imager::Probe can now probe for libraries with dependent libraries, common for static linking, eg. libpng requires libz. https://rt.cpan.org/Ticket/Display.html?id=74043 - libpng 1.5 specific probes were looking for libpng 1.4 filenames. - added alternative probe configurations that try to link libz, to handle a statically linked libpng. https://rt.cpan.org/Ticket/Display.html?id=74043 - if a probe includes testcode, Imager::Probe now checks that code as part of the process of checking each configuration rather than as a post test of the found configuration. This allows alternate configurations to be checked if a matching but non-working configuration is found. https://rt.cpan.org/Ticket/Display.html?id=74043 Other changes: - when reading or writing images via callbacks, the default callbacks now push an error message indicating that a required callback was called but not supplied. https://rt.cpan.org/Ticket/Display.html?id=76782 - clarify which callbacks are required for reading and writing TIFF images. - improve logging for creation of callback I/O layers. - a little more documentation for Imager::Probe. - the i_get_file_background() and i_get_file_backgroundf() APIs now return int to indicate whether the i_background tag was found. - PNG rework - improve error reporting - add png_interlace, png_bits tags - read paletted images as paletted images, including transparency - read 1 bit greyscale images as a type suitable for other file handlers to write as bilevel - read 16 bit/sample PNG as 16-bit/sample Imager images - write "bilevel" paletted images as 1 bit grayscale images - write paletted images as paletted images - write 16-bit (or higher)/sample images as 16-bit/sample PNG images - improved metadata support https://rt.cpan.org/Ticket/Display.html?id=29268 Imager 0.89 - 18 Mar 2012 =========== Bug fixes: - getpixel(..., type => "float") and the API i_gpixf() have been broken on paletted images since they were implemented. https://rt.cpan.org/Ticket/Display.html?id=75258 Other changes: - links in the METHOD INDEX now point at the method documentation rather than the heading you can find them under. https://rt.cpan.org/Ticket/Display.html?id=71495 - Imager (and the bundled dynamic modules) no longer fallback to using DynaLoader if loading via XSLoader fails. For the bundled modules this could hide useful error messages. https://rt.cpan.org/Ticket/Display.html?id=75560 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a buffer in the array of allocations, but just stores the filename pointer and line number. https://rt.cpan.org/Ticket/Display.html?id=70388 Imager 0.88 - 22 Feb 2012 =========== - describe how to build libgif etc on OS X in such a way as to be compatible with a fat binary perl (such as the system perl), in README. https://rt.cpan.org/Ticket/Display.html?id=73371 - update the change notes for 0.77_01 to indicate that libungif support was removed. - add some other imaging modules to SEE ALSO https://rt.cpan.org/Ticket/Display.html?id=73906 - note that the generator of the apparently non-DFSG-free postscript in MMOne.pfb is a Debian package. - setsamples() is now a true complement to getsamples() - it can write 8-bit or floating point samples from a scalar or array reference. This adds i_psamp() and i_psampf() to the C level API. - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have changed to make better use of the typemap, but these aren't part of the perl level API anyway. There were no changes to the C level interfaces to these functions. - getpixel() and setpixel() now accept a mix of scalar and array references for the x and y parameters, and unequal array lengths is no longer an error. https://rt.cpan.org/Ticket/Display.html?id=73697 Bug fixes: - correctly calculate the size of a rotated image https://rt.cpan.org/Ticket/Display.html?id=69261 - fix incorrect rounding of color values for matrix_transform() and rotate(). https://rt.cpan.org/Ticket/Display.html?id=69261 - Win32 text output is now done in normal combine mode, the alpha component of the color is now significant. https://rt.cpan.org/Ticket/Display.html?id=70014 - remove long unused gif case from read() https://rt.cpan.org/Ticket/Display.html?id=69244 (partial) - the getsamples() target parameter was being treated as a hashref when it's meant to be an array reference. https://rt.cpan.org/Ticket/Display.html?id=74882 - getpixel() and setpixel() now returns an empty list when invalid parameters are supplied. Invalid values for type now result in an error for getpixel(). https://rt.cpan.org/Ticket/Display.html?id=73697 Imager 0.87 - 03 Jan 2012 =========== - document the return value of the filter() method. https://rt.cpan.org/Ticket/Display.html?id=72369 - document i_gsamp_bits() and i_psamp_bits(). https://rt.cpan.org/Ticket/Display.html?id=68815 - properly increment the Imager::Matrix2d $VERSION. - actually include the Imager::Test tests in the dist - correctly read and write 256x256 pixel ICO files https://rt.cpan.org/Ticket/Display.html?id=69599 - make the error message from read() or read_multi() when they can't identify the file type match reality. https://rt.cpan.org/Ticket/Display.html?id=72475 - read() now uses $FORMATGUESS if it can't determine the file type based on the file header, to match read_multi(). - re-work and add tests for def_guess_type(). def_guess_type() no longer returns any random file extension as the file type. - add gray4, gray16 and gray as presets for make_colors. https://rt.cpan.org/Ticket/Display.html?id=67911 - add make_palette() method that produces a palette from one or more images. - fix the Imager dependency for the separately distributed font drivers. https://rt.cpan.org/Ticket/Display.html?id=72643 - fix i_render_color() to properly draw in "normal" mode - ie. when writing to a 1 or 3 channel image the second or fourth channel of the source color was being ignored, it is now significant. https://rt.cpan.org/Ticket/Display.html?id=71564 Imager 0.86 - 31 Oct 2011 =========== - improve error reporting for W32 tests Imager 0.85_02 - 24 Oct 2011 ============== Bug fixes: - eliminate unused i_gif_opts type (clean-up) https://rt.cpan.org/Ticket/Display.html?id=69245 - fix combine=0 fill color anti-aliasing on the double/sample path https://rt.cpan.org/Ticket/Display.html?id=71309 - make default text color non-transparent https://rt.cpan.org/Ticket/Display.html?id=71469 - apply the last of the Debian unforwarded spelling fixes https://rt.cpan.org/Ticket/Display.html?id=70656 - the log() method used its message parameter as a C level format string. https://rt.cpan.org/Ticket/Display.html?id=71653 - provide our own STRLEN typemap entry for older perls. https://rt.cpan.org/Ticket/Display.html?id=71641 - add extra ppport.h configuration to support older perls. - depend on Scalar::Util, since we use it and older perls don't have it. - add overloaded eq to Imager::Matrix2d, since older perls don't seem to synthesize it from overloaded "". - use T1_StrError() for error messages on modern libt1 https://rt.cpan.org/Ticket/Display.html?id=69879 - actually load the font rather than just adding it to the catalog on creation. - Imager::Font->new now produces better error messages for the T1 engine. - the font has_chars() method now returns perl's true and false values in list context rather than integers, which should be more efficient. https://rt.cpan.org/Ticket/Display.html?id=69158 - the btm data structure used by the flood_fill code is now initialized more efficiently. https://rt.cpan.org/Ticket/Display.html?id=68994 - updated the Thanks list in README https://rt.cpan.org/Ticket/Display.html?id=71607 - check there's at least one coefficient for the convolution filter https://rt.cpan.org/Ticket/Display.html?id=68993 - make the APIRef synopsis ordering consistent, older versions of perl could order it differently. https://rt.cpan.org/Ticket/Display.html?id=71675 - we rely on Config.pm's d_vsnprintf as to whether we use vsnprintf/snprintf, which is defined in the Win32 Config.pm even though it only has _ prefixed versions of these. Define our own prefixed names on Win32. https://rt.cpan.org/Ticket/Display.html?id=71642 - fix library detection with MSVC - search a few more library directories, so EU::MM doesn't discard them. Hopefully fixes: https://rt.cpan.org/Ticket/Display.html?id=71643 Imager 0.85_01 - 10 Oct 2011 ============== - add simple tests for the Imager::Test test_image generators - io_glue I/O buffering re-work: - reorganize io_glue to do it's own buffering by default - the unbuffered functions are available as i_io_raw_read() (or raw_read() from perl) etc but are not recommended for typical use. - use the new i_io_peekn() when checking for file magic to avoid seek, allowing Imager to detect the file type and read the file from an unseekable stream (for formats that don't use random access) - added several new I/O layer API functions. - fix the TGA performance problem, most noticably on Win32 https://rt.cpan.org/Ticket/Display.html?id=70037 - TIFF now uses wrapper functions of the correct types to avoid casts https://rt.cpan.org/Ticket/Display.html?id=69912 - the callback IO object did its own buffering, controlled by the maxbuffer parameter supplied to the read() and write() methods. This buffering has been removed, to avoid redundancy with the common io_glue buffering. This also avoids a bug in that code which could rarely pass a zero length to the read callback and then panic about the result. - the callback IO object now tests the result of calling the close callback, which should return true for success. - the PNM reader did its own buffering. This buffering has been removed to avoid redundancy with the common io_glue buffering. - previously the read handlers for fd and callback I/O layers would call the underlying interface (POSIX read or your supplied callback) until it filled the buffer. It now only makes one call. - added public constructors for I/O layer objects (see Imager::IO) - all core file handlers now use the i_io_foo() wrappers to gain access to buffered I/O rather than calling the I/O layer callbacks directly. - all core file handlers now check for error on close. - Backward compatibility: if you hava custom file handlers, you can use i_io_write() etc since they're available as macros in older versions of Imager. - eliminate the final remnants of io_glue_commit_types(). - bump IMAGER_API_VERSION, since the above may break assumptions. - removed the long unused i_gen_reader() and i_gen_writer() utility functions. Imager 0.85 - 29 Aug 2011 =========== The main changes in the release versus 0.84 are: - on 64-bit systems, 64-bit types are consistently used for image dimensions and co-ordinated, and for memory block sizes. - handle IFD loops in TIFF files correctly. Previously this would lead to an infinite loop. Bug fixes: - fix the link in the getheight() entry in the method index Imager 0.84_02 - 22 Aug 2011 ============== Development release, this will become 0.85 if CPAN testers is favourable. Bug fixes: - the image file limits set by set_file_limits() weren't being checked when reading TIFF files. https://rt.cpan.org/Ticket/Display.html?id=69915 - Provide more information about file format module load errors on a failed image file read() or write(). https://rt.cpan.org/Ticket/Display.html?id=69194 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate through TIFF images, since it checks for IFD loops. https://rt.cpan.org/Ticket/Display.html?id=69914 - don't leak memory when out of range palette indexes are supplied to setscanline(). https://rt.cpan.org/Ticket/Display.html?id=69242 - require a later version of CPAN::Meta to ensure JSON::PP and CPAN::Meta::YAML are available. https://rt.cpan.org/Ticket/Display.html?id=69008 - hoist the per-line calculations for the flines implementations, and modernize the tests a bit. https://rt.cpan.org/Ticket/Display.html?id=70126 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use them when available. https://rt.cpan.org/Ticket/Display.html?id=69147 - if t1lib failed to reinitialize it would be left as marked initialized. https://rt.cpan.org/Ticket/Display.html?id=69877 - update the bundled (and still modified) Devel::CheckLib https://rt.cpan.org/Ticket/Display.html?id=69170 Imager 0.84_01 - 8 Aug 2011 ============== Development release as a sanity check for the types re-work. Massive types re-work: - the type used internally for pixel co-ordinates and image sizes is now 64-bit on 64-bit platforms (at least sane ones). - size_t is now used consistently for memory block sizes. - since this changes the binary interface, the Imager API version has been incremented. Any module that uses the API will need to be rebuilt. In most cases that will be enough, but calls to any APIs that take a pointer to image sizes may need source changes. - you should be able to create very large images on 64-bit systems, if you have enough memory. Successfully created a 32768 x 49192 x 3 channel image, filled with a tiled image and scaled it. The unscaled image was also successfully saved to a JPEG. - check the image size before attempting to write BMP, GIF, JPEG, PNG, SGI, TGA, TIFF images. - correctly handle reading TGA images over 32767 pixels wide or tall. Incidental changes: - the gif_left and gif_top tags are now clamped to non-negative values when writing a GIF image. - removed dead callback read/write code The default maximum memory size when reading files is now 1G. Imager 0.84 - 20 Jun 2011 =========== - Imager no longer inherits from Exporter (unless you're running an old, old perl. - Imager can now write progressive JPEGs (it could always read them). https://rt.cpan.org/Ticket/Display.html?id=68691 Bug fixes: - re-work, document and test Imager's logging facility. https://rt.cpan.org/Ticket/Display.html?id=65227 - fix META.yml testing and the generated META.yml https://rt.cpan.org/Ticket/Display.html?id=65235 - test and add error reporting to to_*() family methods - add to_rgb_double() method. https://rt.cpan.org/Ticket/Display.html?id=65101 - Imager no longer exports anything by default https://rt.cpan.org/Ticket/Display.html?id=65228 - convert colors to grayscale if the supplied (or generated) palette contains only grays when performing error diffusion color translation. https://rt.cpan.org/Ticket/Display.html?id=68508 - writing a paletted image to GIF wouldn't always use the colors supplied (or generated, eg. via make_colors => "mono"), which was confusing at best. https://rt.cpan.org/Ticket/Display.html?id=67912 - replace (imager|tony)@imager.perl.org in the doc, since I don't plan to continue receiving mail at that address. https://rt.cpan.org/Ticket/Display.html?id=68591 Imager 0.83 - 21 May 2011 =========== Bug fixes: - diag() the error message on failure for some TIFF tests that are failing on a Solaris smoker. http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45 Imager 0.82_01 - 17 May 2011 ============== Dev release, in case the compose tests are too sensitive. Bug fixes: - Imager::Font::T1 incorrectly checked for absolute filename under Win32. Thanks to kmx for the report and fix. https://rt.cpan.org/Ticket/Display.html?id=67963 - compose() with the target, source or mask position off the top or left of the target image didn't clip the source image correctly. https://rt.cpan.org/Ticket/Display.html?id=67220 - compose() now returns a useful error message on a non-positive opacity. - compose.im now at 100% test coverage. (As opposed to, umm, much, much less.) Imager 0.82 - 14 Mar 2011 =========== Bug fixes: - eliminate calls to i_has_format() from the test suite, since it's no longer a useful way to check for file format support. Eliminate i_has_format() from the functions exposed via XS. https://rt.cpan.org/Ticket/Display.html?id=65863 - eliminate calls to note(), which isn't in the (very old) version of Test::More we have as a pre-requisite. note() is modern enough that I don't feel a need to require a Test::More upgrade for it. https://rt.cpan.org/Ticket/Display.html?id=65864 - skip the threads tests on Test::More 2.00_* https://rt.cpan.org/Ticket/Display.html?id=65812 - add an (unshipped) test to check Imager's internal POD links https://rt.cpan.org/Ticket/Display.html?id=65749 - improve the library detection summary https://rt.cpan.org/Ticket/Display.html?id=9675 - increase the version of Imager::Font::Type1 so that upgrades don't downgrade the version in this file. https://rt.cpan.org/Ticket/Display.html?id=66250 - if we see an -rpath (or -R) option in $Config{lddlflags} supply that option for the directories that would normally go in LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH. https://rt.cpan.org/Ticket/Display.html?id=65955 Imager 0.81 - 14 Feb 2011 =========== - added coverage tests for masked images (maskimg.c @100% test coverage) - add hsv() method to Imager::Color Thanks to Leolo (Philip Gwyn) https://rt.cpan.org/Ticket/Display.html?id=65385 - split libt1 Type 1 font support into a sub-module https://rt.cpan.org/Ticket/Display.html?id=49616 (partial) - add a preload() class method for use in forking servers, and to work around limitations in PAR. https://rt.cpan.org/Ticket/Display.html?id=65665 Bug fixes: - paletted writes to a masked image are now masked correctly. Revealed by new coverage tests. - update the filter plugin documentation. https://rt.cpan.org/Ticket/Display.html?id=56513 - add the matrix() method to Imager::Matrix2d to allow creation of a matrix with specified co-efficients. You can now multiple an Imager::Matrix2d object by a 9 element array ref or a number. https://rt.cpan.org/Ticket/Display.html?id=29938 - really fix loading TTF fonts with FT2 when FT1 isn't available. Thanks to Leolo (Philip Gwyn) https://rt.cpan.org/Ticket/Display.html?id=65386 https://rt.cpan.org/Ticket/Display.html?id=62855 - make sure each test script that needs testout/ creates it. https://rt.cpan.org/Ticket/Display.html?id=65088 - handle a slightly different warning from libtiff 4.x https://rt.cpan.org/Ticket/Display.html?id=65268 - the sat transform2() op returned an incorrect saturation. https://rt.cpan.org/Ticket/Display.html?id=65391 Imager 0.80 - 17 Jan 2011 =========== - added coverage tests for Imager::Fountain and Imager::Color::Float - Imager is now maintained in git http://git.imager.perl.org/imager.git git://git.imager.perl.org/imager.git Bug fixes: - images with an translucent alpha channel were not scaled correctly by the default (qtype=normal) scaling method. https://rt.cpan.org/Public/Bug/Display.html?id=63922 - Imager::Color::Float now translates "#FFFFFF" to white instead of just a little darker. - make the default color map build algorithm "mediancut". This changes the default color map builder for writing GIFs back to what it was in 0.77, reverting a performance regression. https://rt.cpan.org/Ticket/Display.html?id=64785 - handle failure to create a masked image correctly Imager 0.79 - 10 Dec 2010 =========== - add Imager::Test to the POD coverage tests and document the missing functions. - the convert() method now optimizes the case where all output channels are either 0, sourced from a single input channel or 1. This significantly speeds up presets like "addalpha", "green". https://rt.cpan.org/Ticket/Display.html?id=51254 - add wiggle.pl sample, as suggested by Dan Oppenheim. - add the combine() method to combine channels from multiple source images into a new image https://rt.cpan.org/Ticket/Display.html?id=11872 Bug fixes: - treat the co-efficients for convert() as doubles instead of floats. - If a higher (earlier) priority font handler failed to load, that would crash preventing loading of later font handlers. https://rt.cpan.org/Ticket/Display.html?id=62855 - parse defines from the options returned by pkg-config --cflags https://rt.cpan.org/Ticket/Display.html?id=63223 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't included in the tarball. They are now included. Imager 0.78 - 4 Oct 2010 =========== Bug fixes: - don't access deprecated members of the png_structp. https://rt.cpan.org/Ticket/Display.html?id=60242 - document that using color objects is faster than supplying colors by name, etc. https://rt.cpan.org/Ticket/Display.html?id=61047 - Imager::Probe now accepts array references for incpath and libpath. https://rt.cpan.org/Ticket/Display.html?id=60244 Imager 0.77_02 - 27 Sep 2010 ============== - moved Win32, FreeType 2 font support into sub-modules. https://rt.cpan.org/Ticket/Display.html?id=49616 (partial) Uses Imager::Probe now. https://rt.cpan.org/Public/Bug/Display.html?id=61328 - tested successfully with jpeg-8b https://rt.cpan.org/Ticket/Display.html?id=60221 Bug fixes: - from _01: look for missing file support test files in the right places. - flood_fill() wouldn't fill the right side of a single scan-line fill area. Thanks to Nicolas Roggli for reporting this. - flood_fill wouldn't fill to the left edge of the image if the starting line didn't reach the left edge. Thanks to Nicolas Roggli for reporting this. Imager 0.77_01 - 13 Sep 2010 ============== - add each library-directory/pkgconfig/ to the pkg-config search path in Imager::Probe. Thanks to Justin Davis. https://rt.cpan.org/Ticket/Display.html?id=60491 - moved GIF, TIFF, JPEG file handling code into sub-modules in preparation for separate distribution. https://rt.cpan.org/Ticket/Display.html?id=49616 (partial) Note: this removed support for libungif from Imager. - optimize filled box drawing (color, not fill) Bug fixes: - Imager::Probe was calling ExtUtils::Liblist to initialize LD_RUN_PATH supplying an undefined value rather than the found directory. Thanks to Justin Davis. https://rt.cpan.org/Ticket/Display.html?id=60491 - only prepend ./ to font filenames when passing them to T1Lib and then only when it would use its search mechanisms. https://rt.cpan.org/Ticket/Display.html?id=60509 - fix the cache check for the X rgb.txt loader. This is typically used for color translation on Unix-like systems, and the fix improves performance of supplying colors by name by about 80 times. Test code that managed 3400 10x10 pixel boxes/second sped up to 25700 boxes/second. - clarify that Imager doesn't write EXIF metadata to images. https://rt.cpan.org/Ticket/Display.html?id=60637 - Imager::Probe can now search subdirectories under its include path. Used by the PNG Makefile.PL to find headers and libraries when they aren't in the base directory, as in cygwin. https://rt.cpan.org/Ticket/Display.html?id=60635 Imager 0.77 - 11 Aug 2010 =========== I don't want Imager::File::PNG indexed as part of Imager, but forgot to update the META.yml before updating the version. - don't index Imager::File::PNG as part of Imager - add resources to META.yml Imager 0.76 - not released =========== Bug fixes: - the align_string() method would ignore a string of "0" due to a mis-use of C< ||= >. Thanks to Maurice Height for reporting this. https://rt.cpan.org/Ticket/Display.html?id=60199 Imager 0.75_03 - 09 Aug 2010 ============== Bug fixes: - read_types() and write_types() would include png when it wasn't available due to a problem with the %formats tie - handle dependent libraries correctly (eg -lpng requiring -lz) in the code run phase of library probing. Imager 0.75_02 - 07 Aug 2010 ============== Bug fixes: - add file missing from MANIFEST, which was causing TIFF failures. Imager 0.75_01 - 06 Aug 2010 ============== Test release for the new PNG probe. - added the ability to read multiple-image PNM files. Note that unlike the pbm/pgm/ppm specification this accepts mixed format files and allows white space padding between files. Thanks to Philip Gwyn (Leolo) for this patch. - moved the PNG file handling code into a sub-module in preparation for separate distribution. https://rt.cpan.org/Ticket/Display.html?id=49616 (partial) Also helps avoid complications from -I/-L compile/link options from other libraries. Bugs: - Imager->new(data => $data) didn't try to process image file data in $data https://rt.cpan.org/Ticket/Display.html?id=58761 - t/t50basicoo.t no longer depends on the other tests to generate its input files. https://rt.cpan.org/Ticket/Display.html?id=9798 Also, it wasn't testing pnm (pnm vs ppm mix-up) - update the documentation of hardinvert to match the change in 0.62. https://rt.cpan.org/Ticket/Display.html?id=59785 - added hardinvertall filter which also inverts the alpha channel (sorry for the mess) - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so the probe can find the library for the test run. https://rt.cpan.org/Ticket/Display.html?id=57518 Imager 0.75 - 20 Jun 2010 =========== - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded perls (not measured) Bugs: - an opacity fill based on a fountain fill would segfault when filling an 8-bit/sample image. - merge thickline branch polygon fix https://rt.cpan.org/Ticket/Display.html?id=43518 Imager 0.74 - 7 May 2010 =========== Bug fixes: - read_multi() didn't handle a missing file format library correctly, aborting on failing to call i_readgif_multi_wiol() or i_readtiff_multi_wiol(). - fix spelling errors patched by Debian http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup - add an (unshipped) author test to spellcheck Imager's POD. - update the TIFF file format documentation https://rt.cpan.org/Ticket/Display.html?id=56510 - lib/Imager/IO.pod was written almost 4 years ago but never shipped. Imager 0.73 - 15 Mar 2010 =========== - implement outline circles, both anti-aliased and not https://rt.cpan.org/Ticket/Display.html?id=19755 - a combine => "none" fill to a 1 or 3 channel image would produce the incorrect colour. Imager 0.72 - 09 Dec 2009 =========== Bump version for release, since 0.71_03 is stable with CPAN testers. Imager 0.71_03 - 5 Dec 2009 ============== - further adjust the threads test so it only performs the tests on perls where it's expected to work, and only if the threads module can be loaded. Imager 0.71_02 - 1 Dec 2009 ============== - adjust the way we load the threads module for the threads test so it works with non-threaded perls Imager 0.71_01 - 30 Nov 2009 =========== Bug fixes: - use scanline oriented operations to flip images instead of pixel operations https://rt.cpan.org/Ticket/Display.html?id=39278 - use double/sample operations to flip large sample images instead of 8-bit sample operations. https://rt.cpan.org/Ticket/Display.html?id=39280 - fix POD nits https://rt.cpan.org/Ticket/Display.html?id=51874 - prevent double-frees when someone creates Imager objects and then creates a thread. Note: this just handles some simple cases, Imager doesn't support perl threads, and isn't likely to. https://rt.cpan.org/Ticket/Display.html?id=52268 Imager 0.71 - 16 Nov 2009 =========== - add the opacity fill type - an adaptor that modifies the opacity of another fill. Bug fixes: - the conv filter now enforces that the sum of the coefficients is non-zero. Also, rather than skipping pixels off the edge off the edge of the image, the closest edge pixel is used. Previously dividing by the zero sum of coefficients could cause invalid results or runtime exceptions. Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing this bug. Imager 0.70 - 21 Sep 2009 =========== Bug fixes: - release image row and comments memory on all error returns in gif reader - handle zero length extensions, previously this would cause a null pointer dereference Thanks to Krzysztof Wojtaś for the test data and fix for this. - an integer division meant that preview scaling to below 1 pixel wide or high (which isn't too useful anyway) was calculating using NaNs on most platforms, and causing an exception on others. Thanks to David Cantrell for producing a backtrace of the crash on his Alpha-NetBSD CPAN test box which made it possible to track this down. Imager 0.69 - 08 Sep 2009 =========== Bug fixes: - broken test fix - was attempting to call a function skip_all, when that should be a parameter to plan(). - briefly document apidocs.perl, the tool used to build Imager::APIRef and make some minor enhancements - various minor documentation enhancements and fixes. Imager 0.68 - 07 Sep 2009 =========== - Imager->new(file => $filename) and other similar incantations will load the given file. https://rt.cpan.org/Ticket/Display.html?id=48261 Bug fixes: - avoid using CHECK as a label in Imager::Test http://nntp.x.perl.org/group/perl.cpan.testers/5220921 - re-work most image file test files that require a library into separate library present/not present files to remove stupidly long conditionals - don't treat rubthrough() outside the bounds of the target image as an error. http://nntp.x.perl.org/group/perl.cpan.testers/5185716 Imager 0.67_01 - 02 Sep 2009 ============== Bug fixes: - correct documentation of default of raw image interleave read parameter https://rt.cpan.org/Ticket/Display.html?id=42074 - add raw_ prefix to raw read parameters, though the original names still work. - fail the read if an invalid raw_interleave parameter is supplied - warn if no interleave or raw_interleave parameter is supplied, since the documented default was wrong, and incompatible with the write format - for reading raw images, if raw_storechannels > raw_datachannels, set the extra channels in the image to 0 - when probing for executables like freetype-config, search for .bat and .cmd on MSWin32, as well as .exe. https://rt.cpan.org/Ticket/Display.html?id=49275 - re-work the external libraries section of README: - list Debian and Redhat package names for each library - reformatting - update URLs - use the new EU::MM META_MERGE facility instead of generating META.yml from scratch https://rt.cpan.org/Ticket/Display.html?id=47888 - use Devel::CheckLib (bundled, modified) to check which release of libtiff is installed and reject 3.9.0 http://bugzilla.maptools.org/show_bug.cgi?id=2088 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079 Imager 0.67 - 12 Dec 2008 =========== Bug fixes: - fix a packaging error Imager 0.66 - 12 Dec 2008 =========== - 24-bit color .ICO/.CUR files can now be read. Bug fixes: - an optimization skipping 0 src alpha values could cause the rubthrough() to read past the end of a buffer. http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html - corrected a reference leak where writing GIFs would leak memory. This could also happen calling to_paletted(). Also documented the underlying long existing feature where the colors parameter is filled with the generated color table and added tests for it. http://rt.cpan.org/Ticket/Display.html?id=41028 - write out the image size in bytes field of a BMP correctly. http://rt.cpan.org/Ticket/Display.html?id=41406 - add limited tests for Imager::ExtUtils - make Imager::ExtUtils->includes use an absolute path, since a relative path could cause failures using Inline::C. http://rt.cpan.org/Ticket/Display.html?id=37353 - re-arrange the POD for Imager::Font::BBox: - mark total_width(), pos_width(), end_offset() obsolete, since they're mostly for backwards compatibility - group width methods and height methods https://rt.cpan.org/Ticket/Display.html?id=39999 Imager 0.65 - 20 May 2008 =========== Bug fixes: - In some cases when an error occurs reading those parts of a JPEG file after the image the scan-line buffer could be freed a second time. In cases where the the error occured while reading the image data it's possible that the buffer could have leaked. Thanks to Gabriel Vasseur for reporting this and help in tracking it down. - the gif_screen_height tag was overriding the screen width and being ignored for the screen height when present. https://rt.cpan.org/Public/Bug/Display.html?id=35568 Imager 0.64 - 23 April 2008 =========== This is a bug fix release. This includes a fix for a possible security issue. Bug fixes: - Possible security issue: The floating point sample path for image based fills had a buffer overflow. This would overwrite the end of a malloc()ed buffer with double precision floats. http://rt.cpan.org/Ticket/Display.html?id=35324 CVE-2008-1928 - check that the result of fileno($fh) is defined rather than simply true when read() or write() is supplied with an fh parameter. http://rt.cpan.org/Ticket/Display.html?id=35139 - i_scale_axis() wasn't checking the result of i_img_new_ch() resulting in a SIGSEGV when attempting to scale an image to a size too large to fit in memory. This is a NULL pointer access issue, not a buffer overflow. Added a check for the failure. scale_calculate() (and hence scale()) will now fail if any of the scale size parameters are a reference. http://rt.cpan.org/Ticket/Display.html?id=35172 - Regression: filling a greyscale image with a hatch used the wrong color channels from the supplied fg/bg colors. https://rt.cpan.org/Ticket/Display.html?id=35278 - fixed a related problem for image fills. Imager 0.63 - 7 April 2008 =========== This release primarily contains changes to improve ease of use - rather than you having to convert images to the appropriate number of channels, Imager handles it internally. How to handle drawing colors and the default combine mode is a thornier problem left for some other release. - the font libraries are now only initialized when needed. http://rt.cpan.org/Ticket/Display.html?id=28825 - moved the imtoc.perl code into Imager::Preprocess - paste() and rubthrough() now adapt the source image data to the destination, so you can now safely paste/rubthrough from greyscale images to color images or back, or from alpha channel images to noalpha channels or back. https://rt.cpan.org/Ticket/Display.html?id=30908 - rubthrough() now falls back to pasting when the source doesn't have an alpha channel. This effectively treats the source as having a max alpha channel, the right thing to do. http://rt.cpan.org/Ticket/Display.html?id=29944 - re-worked most of the area filling code to use a common set of functions when filling. Corrected normal combine mode. Rewrote most of the combine modes to match the way the SVG draft defines them with respect to a translucent source and destination. Added tests for translucent source and destination. Added tests to check 8-bit/sample and double/sample combines work similarly. https://rt.cpan.org/Ticket/Display.html?id=29879 - writing a 2 or 4 channel image to a JPEG file will now write that image as if composited against a background, black by default, overridable with the i_background tag/parameter. https://rt.cpan.org/Ticket/Display.html?id=29876 - writing a 2 or 4 channel image to a PGM/PPM file will now write that image as if composited against a background, black by default, overridable with the i_background tag/parameter. http://rt.cpan.org/Ticket/Display.html?id=30074 - writing a 2 or 4 channel image to a BMP file will now write that image as if composited against a background, black by default, overridable with the i_background tag/parameter. http://rt.cpan.org/Ticket/Display.html?id=30075 Bug fixes: - Imager::Matrix2d->translate() now only requires one of the x or y parameters. http://rt.cpan.org/Ticket/Display.html?id=29937 - mixing qtype scaling now sets all channels of a pixel to zero if the pixel has zero coverage (zero alpha). This should produce more compressible output files. http://rt.cpan.org/Ticket/Display.html?id=32324 - removed the pointless #! line from lib/Imager/Font/Wrap.pm Noticed when I saw: https://bugzilla.redhat.com/show_bug.cgi?id=166254 I'm not changing the #! lines of the sample code, since it's sample code, not intended for installation. http://rt.cpan.org/Ticket/Display.html?id=33408 - some TGA images weren't being detected correctly as TGA images https://rt.cpan.org/Ticket/Display.html?id=32925 - handling of the left-over bit for 16-bit/pixel TGA images has been changed to match the behaviour of the GIMP. Previously the bit being set was treated as an opaque pixel, but one user reported a problem with loading such an image. I haven't been able to find any tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so I'll match it's behaviour. See issue 114913 in the GIMP's bugzilla. http://rt.cpan.org/Ticket/Display.html?id=32926 Imager 0.62 - 10 December 2007 =========== - Makefile.PL now expands ~/path supplied to --incpath or --libpath to /path under your home directory. http://rt.cpan.org/Ticket/Display.html?id=29484 - the old dynaload code used Mach API functions to load dynamic libraries on Mac OS X. These APIs have been deprecated in OS X 10.5 and were causing some build problems. So henceforth Imager uses the dlopen() family of functions, and you will need version 10.3 or later of OS X. - added the det() function to the transform2() engine. added the sample quad_to_square.pl Courtesy Richard Fairhurst. http://rt.cpan.org/Ticket/Display.html?id=31244 Bug fixes: - samples/gifscale.pl sourced the base value for gif_top from gif_left. Thanks to Eleneldil G. Arilou for pointing this out. - t/t82inline.t no longer loads B at runtime, to work around a bug in some 5.005_0[45] installations. http://rt.cpan.org/Ticket/Display.html?id=30508 - work around Module::Depends::Intrusive bug #21229 http://rt.cpan.org/Ticket/Display.html?id=30520 - the hardinvert filter no-longer inverts the alpha channel. http://rt.cpan.org/Ticket/Display.html?id=30002 - the hardinvert filter now supports large samples Imager 0.61_02 - 28 November 2007 ============== - major TIFF support re-work http://rt.cpan.org/Ticket/Display.html?id=20329 - added a C level image interface for accessing samples from 1-32 bits, exposed this at the perl level in getsamples() - the conv filter now works at floating point precision for high bit images - added is_bilevel method to test whether an image should be written as a bilevel image if the image format supports it. - added -log-stderr as an Imager import list option - added some important types to Imager::APIRef - added test_image_double() to Imager::Test Bug fixes: - Imager::Fountain couldn't read GIMP gradient files with 10 or more segments - the scale() method with qtype mixing now handles images with an alpha channel correctly. - fixed a broken link from the "animated GIF" entry in the concept index. Thanks to Slaven Rezic. http://rt.cpan.org/Ticket/Display.html?id=30889 - on some perl's the infix expression parser test would fail due to actions in the grammar returning false. Made sure all actions return a true value. Thanks to Richard Fairhurst for spending a lot of time in tracking down this problem. http://rt.cpan.org/Public/Bug/Display.html?id=29562 Imager 0.61 - 5 November 2007 =========== - added samples/gifscale.pl, which adjusts the screen size/position tags when scaling an animated gif http://rt.cpan.org/Ticket/Display.html?id=27591 Bug fixes: - correct handling of sz in matrix_transform() - this should allow perspective type transformations to work now. http://rt.cpan.org/Ticket/Display.html?id=29936 - prevent a cast to integer warning on x64 builds in datatypes.c also fixed some other type warnings https://rt.cpan.org/Ticket/Display.html?id=30204 - some sub-directory tests depended on files produced by the parent directory tests http://rt.cpan.org/Ticket/Display.html?id=30203 - Imager::Font::Wrap doesn't correctly set savepos thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this. http://rt.cpan.org/Ticket/Display.html?id=29771 - test 171 in t/t01introvert.t was failing on perls configured to use long double. http://rt.cpan.org/Ticket/Display.html?id=29413 - the code for the transform2() uminus operator was missing a break. Added tests for better code coverage of the ops. http://rt.cpan.org/Ticket/Display.html?id=29296 - the SGI RLE compression code could overflow its compression buffer http://rt.cpan.org/Ticket/Display.html?id=30334 - the 32-bit output function used by the SGI code only handled values under 0x10000. This was most noticable when writing large RLE images. http://rt.cpan.org/Ticket/Display.html?id=30335 - validate chan_count for chans == NULL for each of the i_gsamp() implementations. http://rt.cpan.org/Ticket/Display.html?id=28985 - attempt to work around the test failure at http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html http://rt.cpan.org/Ticket/Display.html?id=29562 - improve the error messages produced when attempting to read or write an unknown image file format. http://rt.cpan.org/Ticket/Display.html?id=30103 - improve the transform2() documentation http://rt.cpan.org/Ticket/Display.html?id=29267 - correctly generate the author key in META.yml http://rt.cpan.org/Ticket/Display.html?id=30377 - correctly blend a rotated (or matrix_transformed()) image when performing interpolation in the presence of an alpha channel. Also corrected the centring of the rotated image on the output image. Imager 0.60 - 30 August 2007 =========== - Finished/rewrote Arnar's old SGI RGB file format support, so Imager now has full SGI RGB image format, including RLE and 16-bit/sample images. https://rt.cpan.org/Ticket/Display.html?id=8666 - logging functions are now available in the API - applied Gabriel Vasseur's patch added documentation, further tests, and support for greyscale images Obviously problems are my fault :) https://rt.cpan.org/Ticket/Display.html?id=28142 - the mask for ICO/CUR images is now applied as an alpha channel to the returned image. For the old behaviour, supply ico_masked => 0 to read() or read_multi(). This should be less confusing when using Imager as a general image processor. https://rt.cpan.org/Ticket/Display.html?id=29001 Bug fixes: - in some cases it's possible for giflib/libungif to return color indexes outside the range of colors defined by the image's palette. We now expand the palette to match the indexes used. Thanks to Gabriel Vasseur for reporting this. - fixed various memory leaks that could occur when failing to read png, jpeg, bmp or tga files. - to avoid confusion, channels not present in the image are returned as zero by getscanline(). This has no effect on the C level i_glin() and i_glinf() API functions which continue to not set the unused channels. - the convert() method now returns an image of the same sample size as the source image. https://rt.cpan.org/Ticket/Display.html?id=28492 - remove repeated text in Imager::Files http://rt.cpan.org/Ticket/Display.html?id=27589 - be even more explicit that scale() and friends don't modify the source image, but return a new image. http://rt.cpan.org/Ticket/Display.html?id=28570 - improve the error message from errstr() when you try to load a font for which the driver hasn't been built in Imager. http://rt.cpan.org/Ticket/Display.html?id=27571 - transparency is now enabled by default when writing GIF images http://rt.cpan.org/Ticket/Display.html?id=27615 - Imager would not load on Windows 98 http://rt.cpan.org/Ticket/Display.html?id=27653 Imager 0.59 - 14 June 2007 =========== Bug fixes: - fixes a regression introduced by the fixes for RT 11972 http://rt.cpan.org/Ticket/Display.html?id=27546 - cropping outside the image would return an Imager object with no low-level image object, instead of returning false. Fixed by: Philip Gwyn (Leolo) http://rt.cpan.org/Ticket/Display.html?id=27509 Imager 0.58 - 16 May 2007 =========== No significant changes from 0.57_01. Imager 0.57_01 - 11 May 2007 ============== - added to_rgb16 to produce a 16-bit/sample version of an image - improve freetype 1.x text output efficiency Bug fixes: - search another place for rgb.txt, and check all the places Imager::Color checks when deciding whether to skip testing it http://rt.cpan.org/Ticket/Display.html?id=26064 - use a convolution kernel size based on the stddev rather than a fixed size when performing a gaussian blur http://rt.cpan.org/Ticket/Display.html?id=25645 - document the difference() method's mindist parameter, and debug it. - put the Imager release number in the Inline::C generated code to regenerate Inline code when a new release of Imager is installed. http://rt.cpan.org/Ticket/Display.html?id=26278 - fix rendering on alpha channel images for the FreeType 1.x driver. http://rt.cpan.org/Ticket/Display.html?id=11972 - fix rendering on alpha channel images for the T1lib driver. http://rt.cpan.org/Ticket/Display.html?id=11972 - reworked library probing, we can now set more than one probe function for a library. Disabled the default (non-freetype-config) library probe and added an extra probe function that searches for both ft2build.h and whatever it includes, and adds -I as needed. Hopefully this will fix build problems like http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html http://rt.cpan.org/Ticket/Display.html?id=26086 Imager 0.57 - 30 Apr 2007 =========== This is a maintenence release fixing a security issue in Imager. - CRITICAL: a specially crafted compressed BMP file can cause a buffer overflow in malloced memory. There will be further discussion of this issue in the ticket below. http://rt.cpan.org/Ticket/Display.html?id=26811 CVE-2007-2459 CVE-2007-2413 The descriptions at cve.mitre.org varied in quality, please see the ticket at rt.cpan.org for a more accurate description of the issue. Imager 0.56 - 1 Apr 2007 =========== - added support for reading 16-bit/sample PGM/PPM images - added support for writing 16-bit/sample PGM/PPM images - improved performance of reading PBM/PGM/PPM images - added support for writing PBM images if the image is paletted and contains only black and white - added a new make_colors value - "mono" - switched from the svn log Changes to a manual Changes to reduce noise - new sample code - samples/flasher.pl Bug fixes: - CRITICAL: the "Imager" typemap entry (not used by Imager itself) was returning an image object with an extra reference, this resulted in a memory leak. http://rt.cpan.org/Ticket/Display.html?id=24992 - fix rendering on alpha channel images for the FreeType 2.x driver http://rt.cpan.org/Ticket/Display.html?id=11972 - reading bmp files now consitently handles short reads. You can now supply a parameter to treat a short read as successful and set i_incomplete http://rt.cpan.org/Ticket/Display.html?id=8426 - previously, reading ASCII PBM files required spaces between samples, even though the format doesn't require that - improved documentation of the unsharpmask filter (I hope) http://rt.cpan.org/Ticket/Display.html?id=25531 - force flushing of the output from i_tt_dump_names() and test output in t/t35ttfont.t to prevent output from being mixed up. https://rt.cpan.org/Ticket/Display.html?id=24859 - rewrite a conditional expression as an if() to hopefully work around a bug in the pre-4.0 GCC Apple shipped with OS X 10.4. https://rt.cpan.org/Ticket/Display.html?id=25561 - avoid Data::Dumper in regops.perl to support older releases of perl https://rt.cpan.org/Ticket/Display.html?id=24391 Imager 0.55 - 16 Dec 2006 =========== This is primarily a bug fix release. Note: Test::More is now a pre-requisite for Imager and is no longer bundled. There is one new feature: - the Win32 font driver now supports UTF8 (RT 22166) http://www.cpanforum.com/threads/3276 http://rt.cpan.org/Ticket/Display.html?id=22166 Several bugs were fixed: - the string() method would not output the string "0" http://rt.cpan.org/Public/Bug/Display.html?id=21770 - fills.c was failing to compile on Solaris 10 (compiler unknown) http://rt.cpan.org/Public/Bug/Display.html?id=21944 - the gif_disposal and gif_user_input tags weren't being read from the file correctly http://rt.cpan.org/Public/Bug/Display.html?id=22192 - gif.c was failing to build under MSVC http://rt.cpan.org/Ticket/Display.html?id=23922 - in some cases strings passed to the string() method were treated as terminated by NUL (chr 0) http://rt.cpan.org/Public/Bug/Display.html?id=21770 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since that's the default build name for zlib on Win32. http://rt.cpan.org/Ticket/Display.html?id=23064 - search $Config{incpath} for headers too, which we should have been doing all along. Win32 font driver fixes: - the global descent value from bounding box was the wrong sign http://www.cpanforum.com/threads/3276 - if the first or last glyph overflowed the left or right side of the advance width they would be clipped Imager 0.54 - 14 Sep 2006 =========== This is primarily a feature release: - a new qtype value 'mixing' has been added to the scale() method. This is faster than 'normal', slower than 'preview'. This is based on the method used by pnmscale, and seems to produce less blurry results than normal. http://rt.cpan.org/Public/Bug/Display.html?id=20677 - the rubthrough() method can now render onto images with an alpha channel. http://rt.cpan.org/Ticket/Display.html?id=20678 - the read_multi() method now falls back to calling doing a single image read via the read() method and write_multi() will now fall back to calling write() if a single image is supplied. This means you can simply call the read_multi() or write_multi() functions without having to check if the type is formatted by that method. http://rt.cpan.org/Ticket/Display.html?id=19457 http://rt.cpan.org/Ticket/Display.html?id=19458 - the GIF loop extension can now be written. If you don't have libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you should upgrade. http://rt.cpan.org/Ticket/Display.html?id=21185 - getscanline() and setscanline() can now read/write palette index based data from/to the image for paletted images, by setting type to 'index'. http://rt.cpan.org/Ticket/Display.html?id=20338 - we no longer hassle you to disable GIF support http://rt.cpan.org/Ticket/Display.html?id=20687 - minor documentation fixes Imager 0.53 - 26 Jul 2006 =========== This is a bugfix release. Some test code was left in a code path not covered by the test suite. A test was added to cover this code path and the test code was removed. http://rt.cpan.org/Public/Bug/Display.html?id=20705 Imager 0.52 - 25 Jul 2006 =========== This is primarily a feature release, but contains a fair few bug fixes, new features: - ability to read and write MS Windows ICO and CUR files - you can now add file format plugins to support new file formats - add POD coverage tests - setcolors() and addcolors() now accept color names and so on instead of requiring Imager::Color objects. http://rt.cpan.org/Ticket/Display.html?id=20056 - flood_fill() can now fill to a specified border color instead of just to the area the same color as the seed. http://rt.cpan.org/Ticket/Display.html?id=19618 Bug fixes: - bounding_box for the T1 driver wasn't converting UTF8 to ascii when calculating the advance width. http://rt.cpan.org/Public/Bug/Display.html?id=20554 - bounding_box for the T1 driver wasn't including leading and trailing spaces in the bounding box as the other drivers did, it also produced strange results for empty strings or strings containing only spaces - when reading CMYK jpeg images they were being transferred to the image object as is, producing a four channel image. It only looked ok due to an old still unfixed Photoshop bug. We now convert from the inverted CMYK that photoshop (and Corel for example) produce into RGB. http://rt.cpan.org/Ticket/Display.html?id=20416 - reading a CYMK TIFF would result in a 4 channel image, reading any image with more than 4 channels (eg. RGB with 2 alpha channels) would result in an error. http://rt.cpan.org/Ticket/Display.html?id=20415 - added /usr/local/include to the default include search path, since we were already searching /usr/local/lib for libraries. And various minor fixes and documentation updates. Imager 0.51 - 23 Apr 2006 =========== - fix a validation bug when processing JPEG EXIF data that can cause a crash http://rt.cpan.org/Public/Bug/Display.html?id=18496 - fix mis-processing of the src_maxx and src_maxy parameters of the paste() method http://rt.cpan.org/Public/Bug/Display.html?id=18712 - fix a problem in Imager's "smart" handling of the color parameter to various methods. http://rt.cpan.org/Public/Bug/Display.html?id=18561 Imager 0.50 - 29 Mar 2006 =========== - CRITICAL: fixes a segmentation fault from attempting to write a 2 or 4 channel image to jpeg or a 2 channel image to tga where the output is an in-memeory buffer. http://rt.cpan.org/Public/Bug/Display.html?id=18397 - fixes an incorrect pointer parameter in the PNG code http://rt.cpan.org/Public/Bug/Display.html?id=18051 - skip Inline::C tests when building in a directory with spaces http://rt.cpan.org/Public/Bug/Display.html?id=18049
