1Imager release history. Older releases can be found in Changes.old

1791cbdb
TC
3Coverity finally finished a build, fix a few problems:
4
5 - reading a color-mapped TGA file with an id string would cause a
6 double-free if the palette was truncated.
7
6494c395
TC
8 - mixing scaling to sizes where the accumulator row, the working
9 output row or the working input row didn't fit into the address
10 space could result in memory leaks. This can probably only be
11 reproduced on very wide floating-point sample images.
12
fc24ca5f 13 - convert an array style function parameter pointer to pointer style
3d7b055c
TC
14 to prevent confusing Coverity in the T1 bounding box implementation.
15
16 - Similarly in the FT1 bounding box implementation.
fc24ca5f 17
20c297d4
TC
18 - Similarly for the i_tt_rasterize() function in the FT1
19 implementation.
20
fc24ca5f
TC
21 - initialize a pointer to prevent Coverity complaining in polygon
22 drawing (it should always end up being set.)
23
f7675b46
TC
24 - addi style makemap could potentially read one past the end of an
25 array.
26
58ec1fde
TC
27 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
28 would result in read beyond the end of the built-in hatch array.
29 Negative values (which Coverity didn't complain about) could also
30 cause problems.
31
b7346865
TC
32 - the Imager::Color set_internal() interal method no longer
33 calls the over-complicated ICL_set_internal() (which is retained
34 only for the old API.) Coverity complained that this leaked, but
35 this could only occur with an invalid (NULL pointer) color object.
36
785364c1
TC
37 - the underlying implementation of the map() method could read before
38 the beginning on an allocated array if supplied with inconsistent
39 parameters, which Coverity complained about. No Imager code calls
40 that function with inconsistent parameters, but a
41 belt-and-suspenders check was added.
42
eb7e48c9
TC
43 - Coverity complained a call to i_getcolors(), used by the
44 implementation of the is_bilevel() method could leave the fetched
45 colors uninitialized. Added a return value check.
46
c1c8b1e9
TC
47 - a numeric combining mode of 13 (eg. as a parameter to
48 Imager::Fill->new())could cause an invalid array read in
49 i_get_combine() due to a fencepost error in validating the combine
50 number.

52Imager 1.008 - 31 Dec 2018
53============
54
75e155e1 55 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
56 This allows file formats that store EXIF data as blobs similarly
57 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 58
b5bbf161 59 - added some more file extensions to image file type mappings
75e155e1
TC
60
61 - added add_type_extensions() class method

TC
80 - the internal i_errors() function now correctly allocates the stack
81 space needed for its result.
82 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
83
84 - t/100-base/020-color.t now uses Imager::Test's test functions
85 instead of its own.
86 https://rt.cpan.org/Ticket/Display.html?id=111993
87
344dda51
TC
88 - write_multi() now returns an error result (a false value) if called
89 with a non-(Imager image object). Previously it would typically
90 crash.
91 https://rt.cpan.org/Ticket/Display.html?id=117878
92
93 - improve the documentation of the jpegquality parameter when
94 writing JPEG files.
95
96 - add code to mitigate CVE-2016-1238, Imager will no longer search the
97 default current directory entry in @INC when searching for file
98 format support modules.

TC
109Imager 1.004_004 - 15 Apr 2016

TC
112 - test that the ivdformat from Config is correct and look for a valid
113 one if it isn't.
114 For the strange Win32 failures.
115
116 - fix a copy and paste error in pod in samples/samp-form.cgi

119================
120
bd2d657d
TC
121 - add some extra error reporting to the I/O layers tests, this might
122 help catch a failure seen on Win32.

125Imager 1.004_002 - 20 Mar 2016
126================
127
735b3e7b
TC
128 - don't use the seek() method on opened() handles in
129 t/200-file/400-basic.t. In older versions of perl such handles are
130 only IO::Handle objects, not IO::File, and don't have a seek()
131 method.

133Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
134================
135
08914ed1
TC
136 - re-work the t/200-file/400-basic.t to correctly handle failures
137 It's custom ok() function didn't have a prototype and didn't use scalar().
138 This caused ok() to use the note instead of the value being tested when
139 the method called returned an empty list. For an example of the problem
e6226ce5 140 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 141
a2791e47
TC
142 - remove some noise from when Imager tried to work with bugs in old
143 versions of giflib. I can't do much about the new bugs.
08914ed1 144
e6226ce5
TC
145 - the new autolevels filter (Imager 0.99) used an integer for the
146 sample scaling factor which caused the top output level to be too
147 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
148 https://rt.cpan.org/Ticket/Display.html?id=111871
149
e6226ce5 150 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
151 minimum and maximum luminance from the histogram. This slightly
152 reduced the contrast of the output image.
153 https://rt.cpan.org/Ticket/Display.html?id=111871
154
155 - the new autolevels filter now uses a lookup table for 8-bit images
156 to avoid a floating point multiply for each sample.
157 https://rt.cpan.org/Ticket/Display.html?id=111871
158
e6226ce5
TC
159 - fixed several memory leaks detected by valgrind:
160
161 - addcolors() leaked the temporary array of colors supplied to the
162 internal API
163
164 - make_palette() leaked the temporary image array (not the images
165 themselves) passed to the internal API.
166
167 - combine()/i_combine() leaked its working row buffers
168
169 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
170 buffer if there were too many colors
171
172 - getcolorcount()/i_count_colors() leaked the sample buffer if
173 there were too many colors.
174
175 - the nearest_color filter (undocumented until I find a use for it)
176 leaked both temporaries passed to the API and internal buffers
177
a2791e47
TC
178 - the internal process of upgrading a paletted image to a direct
179 color image would leak a context object reference count.
180
181 - a write failure when writing to a GIF file could leak memory.
182
183 - failing to write to a 1-bit/pixel ICO image could leak memory.
184
185 - Imager no longer deliberately leaks the context object from the
186 initial thread. This was done to ensure there was always a context
187 object available, but the code that needed that now handles the
188 lack correctly,
189
e6226ce5
TC
190 - fixed some uninitialized memory usage detected by valgrind:
191
192 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
193 i_matrix_transform_bg() didn't initialize a working color value
194 if there was zero pixel coverage.
195
196 - i_ft2_cp() didn't initialize the complete color when producing an
197 intermediate image. This caused uninitialized value usage when
198 logging the color.

216Imager 1.003 - 12 May 2015
217============
218
0fda3cfd
TC
219 - update 1.002 release notes to include the center change for filled
220 circle drawing.
221
222 - flood_fill() would escape beyond a 4-connected space under some
223 circumstances.
224 Added many more flood_fill() tests.

TC
227Imager 1.002 - 3 Apr 2015
228============
229
334b8922
TC
230 - drawing anti-aliased filled circles is now 10 to 50 times faster
231 depending on the size of the circle.
0fda3cfd
TC
232 This also changed the center from being the center of the pixel to
233 being the top left of the pixel to match the filled arcs drawn by
234 arc().
334b8922
TC
235 https://rt.cpan.org/Ticket/Display.html?id=101682
236
237 - enhancements to polygon filling:
238
239 - added a mode parameter to control how overlapping regions behave
240
241 - added a polypolygon() method to fill more than one polygon at a
242 time
243
244 - polygon filling is now exposed through the API.
245
45c8e262
TC
246 - added colormodel(), alphachannel() and colorchannels() methods.
247 These were added for two reasons:
248
249 - a future version of Imager may allow the number of channels in
250 an image to not directly represent the color model of an image.
251 eg. a greyscale TIFF image with multiple alpha channels.
252
253 - a future version of Imager may allow an image to be read without
254 translation, for example a TIFF file that contains measurements
0fda3cfd 255 from an instrument. Currently Imager transforms the samples into
d96c4de8 256 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
257 the value back.
258
259 An untranslated image would be unusable as image data, so
260 colormodel() would return "unknown" in this case.
261
262 Similarly a CMYK image might be returned as an "unknown" color
263 model image, if the caller chooses to disable translation to
264 RGB.

269 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
270 Thanks to Slaven Rezic for the report and the patch.

297There's nothing special about Imager 1.000, it's just another release.
298
fa3dac1d
TC
299 - fix the skip check for the iolayer qr// buffer test

304Imager 0.99_02 - 21 Jul 2014
305==============
306
5dab5b9a
TC
307 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
308 the blue channel in the generated palette, and allow each color
309 component to be in the range 100..255 instead of just 100..254.
310 Thanks to Ralf Neubauer.
311 https://rt.cpan.org/Ticket/Display.html?id=97086
312
313 - revert "improved the XS for i_io_read() and i_io_raw_read()"
314 This caused problems with older perls and didn't provide much of a
315 performance improvement.
316
5bf25bc2 317 - support Inline 0.57 and later.
6d47a6af 318 Inline 0.57 changed the "with" interface.

TC
321 - don't define our own MAXINT macro, it conflicts with windows header
322 files and in a few places it was the wrong value to use anyway.

TC
328 - GIF: add support for giflib 5.1.0, which added error code pointer
329 parameters to EGifCloseFile() and DGifCloseFile().

331
332 - GIF: avoid a double-free when do_write() fails.

341Imager 0.99 - 25 Jun 2014
342===========
343
dce1523b
TC
344 - Imager::IO->new_buffer() (and hence Imager->read()'s data
345 parameter) now accepts a reference to a scalar as well as just a
346 plain scalar.
6a160bce 347 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
348
349 - Imager::IO->new_buffer() now always makes a copy of the passed in
350 buffer to avoid problems with temporary objects used for the return
351 value of SvPVbyte().
6a160bce 352 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 353

355 https://rt.cpan.org/Ticket/Display.html?id=92738
356
357 - load plugins from absolute paths on Android
358 Thanks to Brian Fraser.
359 https://rt.cpan.org/Ticket/Display.html?id=93272
360
6a160bce
TC
361 - added the jpeg_optimize parameter for writing JPEG files. This can
362 significantly reduce file sizes, but uses more memory and time.
363 https://rt.cpan.org/Ticket/Display.html?id=94292
364
14fd9e5d
TC
365 - the autolevels filter now works on the luminosity of the image
366 rather then working per channel. The old autolevels filter is
367 still available as "autolevels_skew".
368 https://rt.cpan.org/Ticket/Display.html?id=94413
369
75d54149
TC
370 - Imager::File::PNG now supports libpng 1.6.10.
371 1.6.10 changed CRC errors from benign errors to normal errors,
372 which broke the test which used CRC errors to check for benign
373 error support. Switched to using a 1-bit grey-scale image with a
374 palette to test for benign errors.

377Imager 0.98 - 3 Jan 2014
378===========
379
f84f86a2
TC
380Incompatible changes:
381
382 - the return value of setpixel() has changed.
383
384 Previously the return values for undrawable pixels vs caller errors
385 changed depending on whether you used the multiple pixel calling
386 mechanism, or the single pixel mechanism.
387
388 Now:
389
390 - for an invalid parameter, such as an unknown colour, or missing
391 parameter, an empty list (or undef in scalar context) is
392 returned, and errstr() is set,
393
394 - otherwise the number of pixels drawn is returned. If none of
395 the pixels could be drawn (they were all outside the image), "0
396 but true" is returned.
397
398 https://rt.cpan.org/Ticket/Display.html?id=87650
399
400Other changes:
401
6ba09ab9
TC
402 - when drawing on an image with an alpha channel where the source
403 minimum is greater than zero, Imager would read from beyond the end
404 of a malloc() allocated buffer. In rare circumstances this could
405 lead to some of the source image not being written to the target
406 image, or possibly to a segmentation fault.
407 I don't believe this has any security concerns beyond that.
408
0d052fd9
TC
409 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
410 text drawn would be nonsense. This would also read beyond the end
411 of a malloced buffer.
412
13671b17
TC
413 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
414 truncated early.
415 https://rt.cpan.org/Ticket/Display.html?id=88993
416
d6f4e964

417 - Imager::Font::Wrap no longer requires the image parameter.

423
0179ecd6
TC
424 - Image::Probe, Imager's internal module for probing library
425 locations now searches the directories specified by LD_RUN_PATH,
426 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
427 and the corresponing s/\blib$/include/ directories for header
428 files.

443 - PNG: the check for benign error support is more complex than a

455 - TIFF: handle SampleFormat = 2 by translating the signed integer
456 values to unsigned by flipping their sign bits.

460 SampleFormat is ignored for paletted images.

TC
462 Mixed SampleFormat are handled incorrectly, since libtiff returns
463 only the first SampleFormat value, and an image with both an alpha
464 channel and SampleFormat = 2 for color channels probably has a
465 different SampleFormat for the alpha channel.

678 The giflib API Imager uses doesn't have a mechanism to set the
679 header version in 5.0.0.
680
681 - update the GIF library probe code to check for the new giflib 5.0.1
682 EGifSetGifVersion() function, and to check for the giflib 4.2.0
683 uninitialized gif89 bug.

TC
714 - The size of rotated images is no longer rounded up so aggressively.
715 Added rounding to the linear interpolation done for rotate() and
716 matrix_transform() for 1 and 3 channel 8-bit images.
717 Adjusted the two tranlate matrices used to build the final rotation
718 matrix to use the distance between the outlier pixels rather than
719 the pixel dimensions (ie. dimension-1).
720 With all of this the output of rotate(degrees => 270) on an 8-bit
721 image exactly matches the output of rotate(right => 270).

723
ef84bb32
TC
724Other changes:
725
726 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
727 internals, those names only matter for the XS interface.
728
729 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
730 the API level compiled into a loadable module such as
731 Imager::File::GIF doesn't match that of Imager. Previously it
732 could be difficult to determine exactly which module was failing to
733 load.
734 https://rt.cpan.org/Ticket/Display.html?id=77173
735
736 - added Imager->check_file_limits() as an interface to the
737 i_int_check_image_file_limits() API.
738
739 - Imager->set_file_limits(reset => 1) now resets the limits to the
740 defaults rather than setting them all to unlimited.

748Bug fixes:

751 parameter but the prototype didn't allow for the extra parameter.
752 Corrected the prototype.
753
29b38678
TC
754 - when downconverting samples (eg. from floating point to 8 bit)
755 Imager now rounds the sample value rather than attempting to
756 allocate input values over output values equally. The old
757 behaviour had the probably surprising effect of converting a
758 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
759 2.
760 This may result in slightly different 8 or 16-bit output images.
761
e2a86bac
TC
762 - BI_BITFIELD BMP images were handled incorrectly, both in
763 incorrectly calculating the space required for the masks and in
764 processing the image data itself.
765 https://rt.cpan.org/Ticket/Display.html?id=76736
766
767 - some odd width BMP BI_RLE4 images use run lengths that run one off
768 the edge of the image. Imager now allows this, discarding the
769 extra column.
770
771 - odd length RLE4 runs in BMP images were decoded incorrectly.
772

TC
773 - pkg-config could sometimes return a library that was in a directory
774 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
775 If no -L is included in the pkg-config library information check if
776 EU::MM can find the library, and if not, search our configured
777 directories and insert that into the library flags.

780 - Imager::Probe can now probe for libraries with dependent libraries,
781 common for static linking, eg. libpng requires libz.
782 https://rt.cpan.org/Ticket/Display.html?id=74043
783
784 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
785
786 - added alternative probe configurations that try to link libz, to
787 handle a statically linked libpng.
788 https://rt.cpan.org/Ticket/Display.html?id=74043
789
790 - if a probe includes testcode, Imager::Probe now checks that code as
791 part of the process of checking each configuration rather than as a
792 post test of the found configuration. This allows alternate
793 configurations to be checked if a matching but non-working
794 configuration is found.

870 - setsamples() is now a true complement to getsamples() - it can
871 write 8-bit or floating point samples from a scalar or array
872 reference. This adds i_psamp() and i_psampf() to the C level API.
873
874 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have

1032 - io_glue I/O buffering re-work:
1033
1034 - reorganize io_glue to do it's own buffering by default
1035
1036 - the unbuffered functions are available as i_io_raw_read() (or
1037 raw_read() from perl) etc but are not recommended for typical
1038 use.
1039
1040 - use the new i_io_peekn() when checking for file magic to avoid
1041 seek, allowing Imager to detect the file type and read the file
1042 from an unseekable stream (for formats that don't use random
1043 access)
1044
1045 - added several new I/O layer API functions.
1046
1047 - fix the TGA performance problem, most noticably on Win32
1048 https://rt.cpan.org/Ticket/Display.html?id=70037

1050 - TIFF now uses wrapper functions of the correct types to avoid casts
1051 https://rt.cpan.org/Ticket/Display.html?id=69912
1052
1053 - the callback IO object did its own buffering, controlled by the
1054 maxbuffer parameter supplied to the read() and write() methods.
1055 This buffering has been removed, to avoid redundancy with the
1056 common io_glue buffering. This also avoids a bug in that code
1057 which could rarely pass a zero length to the read callback and
1058 then panic about the result.
1059
1060 - the callback IO object now tests the result of calling the close
1061 callback, which should return true for success.
1062
1063 - the PNM reader did its own buffering. This buffering has been
1064 removed to avoid redundancy with the common io_glue buffering.
1065
1066 - previously the read handlers for fd and callback I/O layers would
1067 call the underlying interface (POSIX read or your supplied callback)
1068 until it filled the buffer. It now only makes one call.
1069
1070 - added public constructors for I/O layer objects (see Imager::IO)
1071
1072 - all core file handlers now use the i_io_foo() wrappers to gain
1073 access to buffered I/O rather than calling the I/O layer
1074 callbacks directly.
1075
1076 - all core file handlers now check for error on close.
1077
1078 - Backward compatibility: if you hava custom file handlers, you can
1079 use i_io_write() etc since they're available as macros in older
1080 versions of Imager.
1081
1082 - eliminate the final remnants of io_glue_commit_types().
1083
1084 - bump IMAGER_API_VERSION, since the above may break assumptions.
1085
1086 - removed the long unused i_gen_reader() and i_gen_writer() utility
1087 functions.

1150Development release as a sanity check for the types re-work.
8d14daab
TC
1151
1152Massive types re-work:
1153
1154 - the type used internally for pixel co-ordinates and image sizes is
1155 now 64-bit on 64-bit platforms (at least sane ones).
1156
1157 - size_t is now used consistently for memory block sizes.
1158
1159 - since this changes the binary interface, the Imager API version has
1160 been incremented. Any module that uses the API will need to be
1161 rebuilt. In most cases that will be enough, but calls to any APIs
1162 that take a pointer to image sizes may need source changes.
1163
1164 - you should be able to create very large images on 64-bit systems,
1165 if you have enough memory. Successfully created a 32768 x 49192 x
1166 3 channel image, filled with a tiled image and scaled it. The
1167 unscaled image was also successfully saved to a JPEG.
1168
1169 - check the image size before attempting to write BMP, GIF, JPEG,
1170 PNG, SGI, TGA, TIFF images.
1171
1172 - correctly handle reading TGA images over 32767 pixels wide or tall.
1173
1174Incidental changes:
1175
1176 - the gif_left and gif_top tags are now clamped to non-negative
1177 values when writing a GIF image.
1178
1179 - removed dead callback read/write code
1180
1181The default maximum memory size when reading files is now 1G.

1771
1772 - In some cases when an error occurs reading those parts of a JPEG
1773 file after the image the scan-line buffer could be freed a second
1774 time. In cases where the the error occured while reading the image
1775 data it's possible that the buffer could have leaked.

1777 it down.

1791 - Possible security issue: The floating point sample path for image
1792 based fills had a buffer overflow. This would overwrite the end of
1793 a malloc()ed buffer with double precision floats.

1797 - check that the result of fileno($fh) is defined rather than simply
1798 true when read() or write() is supplied with an fh parameter.
1799 http://rt.cpan.org/Ticket/Display.html?id=35139
1800
1801 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1802 resulting in a SIGSEGV when attempting to scale an image to a size
1803 too large to fit in memory. This is a NULL pointer access issue,
1804 not a buffer overflow.
1805 Added a check for the failure.
1806 scale_calculate() (and hence scale()) will now fail if any of the
1807 scale size parameters are a reference.

1819This release primarily contains changes to improve ease of use -
1820rather than you having to convert images to the appropriate number of
1821channels, Imager handles it internally. How to handle drawing colors
1822and the default combine mode is a thornier problem left for some other
1823release.

TC
1828 - moved the imtoc.perl code into Imager::Preprocess
1829
1830 - paste() and rubthrough() now adapt the source image data to the
1831 destination, so you can now safely paste/rubthrough from greyscale
1832 images to color images or back, or from alpha channel images to
1833 noalpha channels or back.
1834 https://rt.cpan.org/Ticket/Display.html?id=30908
1835
1836 - rubthrough() now falls back to pasting when the source doesn't have
1837 an alpha channel. This effectively treats the source as having a
1838 max alpha channel, the right thing to do.
1839 http://rt.cpan.org/Ticket/Display.html?id=29944
1840
1841 - re-worked most of the area filling code to use a common set of
1842 functions when filling.
1843 Corrected normal combine mode.
1844 Rewrote most of the combine modes to match the way the SVG draft
1845 defines them with respect to a translucent source and destination.
1846 Added tests for translucent source and destination.
1847 Added tests to check 8-bit/sample and double/sample combines work
1848 similarly.

1884 - some TGA images weren't being detected correctly as TGA images
1885 https://rt.cpan.org/Ticket/Display.html?id=32925
1886
1887 - handling of the left-over bit for 16-bit/pixel TGA images has been
1888 changed to match the behaviour of the GIMP. Previously the bit
1889 being set was treated as an opaque pixel, but one user reported a
1890 problem with loading such an image. I haven't been able to find any
1891 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1892 I'll match it's behaviour. See issue 114913 in the GIMP's
1893 bugzilla.

1903 - the old dynaload code used Mach API functions to load dynamic
1904 libraries on Mac OS X. These APIs have been deprecated in OS X
1905 10.5 and were causing some build problems.

1907 will need version 10.3 or later of OS X.

2179Bug fixes:
2180
2181 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
2182 was returning an image object with an extra reference, this
2183 resulted in a memory leak.
2184 http://rt.cpan.org/Ticket/Display.html?id=24992
2185
2186 - fix rendering on alpha channel images for the FreeType 2.x driver
2187 http://rt.cpan.org/Ticket/Display.html?id=11972
2188
2189 - reading bmp files now consitently handles short reads. You can now
2190 supply a parameter to treat a short read as successful and set
2191 i_incomplete
2192 http://rt.cpan.org/Ticket/Display.html?id=8426
2193
2194 - previously, reading ASCII PBM files required spaces between samples,
2195 even though the format doesn't require that

2211Imager 0.55 - 16 Dec 2006
2212===========
2213
2214This is primarily a bug fix release.
2215
2216Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2217
2218There is one new feature:
2219
2220 - the Win32 font driver now supports UTF8 (RT 22166)
2221 http://www.cpanforum.com/threads/3276
2222 http://rt.cpan.org/Ticket/Display.html?id=22166
2223
2224Several bugs were fixed:
2225
2226 - the string() method would not output the string "0"
2227 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2228
2229 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2230 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2231
2232 - the gif_disposal and gif_user_input tags weren't being read from
2233 the file correctly
2234 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2235
2236 - gif.c was failing to build under MSVC
2237 http://rt.cpan.org/Ticket/Display.html?id=23922
2238
2239 - in some cases strings passed to the string() method were treated as
2240 terminated by NUL (chr 0)
2241 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2242
2243 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2244 that's the default build name for zlib on Win32.
2245 http://rt.cpan.org/Ticket/Display.html?id=23064
2246
2247 - search $Config{incpath} for headers too, which we should have been
2248 doing all along.
2249
2250Win32 font driver fixes:
2251
2252 - the global descent value from bounding box was the wrong sign
2253 http://www.cpanforum.com/threads/3276
2254
2255 - if the first or last glyph overflowed the left or right side of the
2256 advance width they would be clipped
2257
2258
2259Imager 0.54 - 14 Sep 2006
2260===========
2261
2262This is primarily a feature release:
2263
2264 - a new qtype value 'mixing' has been added to the scale()
2265 method. This is faster than 'normal', slower than 'preview'. This
2266 is based on the method used by pnmscale, and seems to produce less
2267 blurry results than normal.
2268 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2269
2270 - the rubthrough() method can now render onto images with an alpha
2271 channel.
2272 http://rt.cpan.org/Ticket/Display.html?id=20678
2273
2274 - the read_multi() method now falls back to calling doing a single
2275 image read via the read() method and write_multi() will now fall
2276 back to calling write() if a single image is supplied. This means
2277 you can simply call the read_multi() or write_multi() functions
2278 without having to check if the type is formatted by that method.
2279 http://rt.cpan.org/Ticket/Display.html?id=19457
2280 http://rt.cpan.org/Ticket/Display.html?id=19458
2281
2282 - the GIF loop extension can now be written. If you don't have
2283 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2284 should upgrade.
2285 http://rt.cpan.org/Ticket/Display.html?id=21185
2286
2287 - getscanline() and setscanline() can now read/write palette index
2288 based data from/to the image for paletted images, by setting type to
2289 'index'.
2290 http://rt.cpan.org/Ticket/Display.html?id=20338
2291
2292 - we no longer hassle you to disable GIF support
2293 http://rt.cpan.org/Ticket/Display.html?id=20687
2294
2295 - minor documentation fixes
2296
2297
2298Imager 0.53 - 26 Jul 2006
2299===========
2300
2301This is a bugfix release.
2302
2303Some test code was left in a code path not covered by the test
2304suite. A test was added to cover this code path and the test code was
2305removed.
2306http://rt.cpan.org/Public/Bug/Display.html?id=20705
2307
2308
2309Imager 0.52 - 25 Jul 2006
2310===========
2311
2312This is primarily a feature release, but contains a fair few bug
2313fixes, new features:
2314
2315 - ability to read and write MS Windows ICO and CUR files
2316
2317 - you can now add file format plugins to support new file formats
2318
2319 - add POD coverage tests
2320
2321 - setcolors() and addcolors() now accept color names and so on
2322 instead of requiring Imager::Color objects.
2323 http://rt.cpan.org/Ticket/Display.html?id=20056
2324
2325 - flood_fill() can now fill to a specified border color instead of
2326 just to the area the same color as the seed.
2327 http://rt.cpan.org/Ticket/Display.html?id=19618
2328
2329
2330Bug fixes:
2331
2332 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2333 calculating the advance width.
2334 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2335
2336 - bounding_box for the T1 driver wasn't including leading and
2337 trailing spaces in the bounding box as the other drivers did, it also
2338 produced strange results for empty strings or strings containing only
2339 spaces
2340
2341 - when reading CMYK jpeg images they were being transferred to the
2342 image object as is, producing a four channel image. It only looked ok
2343 due to an old still unfixed Photoshop bug. We now convert from the
2344 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2345 http://rt.cpan.org/Ticket/Display.html?id=20416
2346
2347 - reading a CYMK TIFF would result in a 4 channel image, reading any
2348 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2349 result in an error.
2350 http://rt.cpan.org/Ticket/Display.html?id=20415
2351
2352 - added /usr/local/include to the default include search path, since
2353 we were already searching /usr/local/lib for libraries.
2354
2355And various minor fixes and documentation updates.
2356
2357
2358Imager 0.51 - 23 Apr 2006

2362 a crash
2363 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2364
2365 - fix mis-processing of the src_maxx and src_maxy parameters of the
2366 paste() method
2367 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2368
2369 - fix a problem in Imager's "smart" handling of the color parameter
2370 to various methods.
2371 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2372
2373
2374Imager 0.50 - 29 Mar 2006
2375===========

2378 or 4 channel image to jpeg or a 2 channel image to tga where the
2379 output is an in-memeory buffer.
2380 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2381
2382 - fixes an incorrect pointer parameter in the PNG code
2383 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2384
2385 - skip Inline::C tests when building in a directory with spaces
2386 http://rt.cpan.org/Public/Bug/Display.html?id=18049
