- tiff reading now uses the error stack
- use the error stack value from reading bmp files
- fix an error message in bmp.c
+ - added has_chars() method to Imager::Font::FreeType2
+ - freetype 2 bounding box function didn't know UTF8 (doh!)
+ - write paletted images as paletted to tiff
+ - initialize counter for packing 4 bit data
+ - don't allocate hashboxes as locals since it overflows the
+ stack by default in Darwin
+ - applied T1 afm patch from Claes Jacobsson
+ - split IM_INCPATH and IM_LIBPATH with $Config{path_sep}, so they
+ work on Windows
+ - Added memory pools for easy cleanup of temp buffers
+ - Added read support for sgi .rgb files.
+ - io_new_fd() now creates a FDSEEK io object
+ - implemented i_readgif_wiol()
+ - Imager->read() now uses i_readgif_wiol();
+ - extend callback iolayers at C and Perl levels
+ - implemented i_writegif_wiol()
+ - split out Perl iolayer initialization into private methods
+ - add tests for each type of iolayer in t50basicoo.t
+ - read/write multi-image tiff files
+ - tests in t50basicoo.t for multi-image/file
+ - ASCII PBM files were reading white as dark gray (255 vs 1)
+ - modify the Freetype2 font code to pick it's own encoding
+ rather than using whatever strange translation FT2 happens to
+ pick
+ - modify the FT1 font code to use the first encoding as a default
+ if we don't find a unicode encoding
+ - use the glyph bbox to calculate the glyph bitmaps for rendering
+ with FT1 rather than the global ascender/descender. This helps
+ with fonts that have broken metrics.
+ - fix calculation of descender for FT2, it was calculating the
+ minimum decent rather than the maximum for the characters in
+ the string
+ - didn't set default for bounding_box() utf8 parameter (caused a
+ warning when calling bounding_box() on a FT2 font with no utf8
+ parameter)

+ - we now log which memory block is being freed before giving
+ an error on it being re-freed
+ - fixed stupid bug in deleting tags
+ - fixed minor pod errors involving >
+
+0.40pre2
+ - make t1log optional, defaulting to off. You can enable the log
+ with Imager::init(t1log=>1) (Ticket #369)
+ - quote a few hash key strings to prevent warnings on 5.004
+ - modify quantization code to handle 1 channel images
+ correctly (Ticket #365)
+ - make channel pointer to i_gsamp() const int * so we can pass
+ const arrays
+ - handle the presence of the default broken giflib better,
+ by giving them some more prose about the problem, and skipping
+ all but the first test that fails with the broken giflib
+ - i_box_cfill() went into an infinite loop on fountain fills
+ or fills on images with more than 8-bits/sample
+ - hide more of our Darwin dlload emulation to prevent runtime
+ symbol conflicts
+ - use INT2PTR() and PTR2IV() macros instead of direct casts to
+ prevent pointer vs int size warnings on 64-bit builds of perl.
+ - add our own INT2PTR and PTR2IV definitions when perl doesn't
+ supply them
+ - difference() method
+ - hide (with static) or rename many symbols that could possibly
+ cause conflicts with other libraries or perl

+ image didn't have one
+ - improve crop() documentation, see
+ http://perlmonks.org/index.pl?lastnode_id=155767&node_id=155428
+ - handle the first "buggy giflib" test more portably. Previously
+ it used fork() which caused problems on systems that didn't have
+ a real fork().
+
+0.41
+ - skip() in testtools should be skipn() and it should use the
+ loop variable for the test number
+
+0.42
+ - quote the 'min' parameter to scale in Imager::Transformations
+ and at least mention it in the docs beyond the examples
+ - document the values for the read() and write() method type
+ parameter
+ - support UTF8 text with Freetype 1.x
+ - second parameter to SvPV() must be of type STRLEN
+ - Doc pathces from cogent.
+ - Fixed out of bounds access on bitmap for flood fills.
+ - some char * vs unsigned char * casts missing on OSF1 v4.0
+ - some enums had , on the last item in datatypes.h, which OSF1
+ didn't like
+ - Compaq C 6.4 (OSF1) claims to be C99 but doesn't provide
+ stdint.h, don't try to use it under OSF

+ drawing algorithm.
+ - support has_chars() method for Freetype 1.x
+ - fixed log message for i_ft2_has_chars()
+ - fixed some broken checking for UTF8 in FT2 code
+ - handle UTF8 strings passed to T1 low-level functions

+ - update the URLs for libpng and zlib
+ - Fixed empty string handling for tt font driver.
+ - Fixed tiff handling of images all contained in a
+ single strip (rowsperstrip = -1) and added a hack
+ for images missing the rowsperstrip tag.
+ - Fixed default parameters for crop()
+ - Added Preliminary specialized scaling code.
+ - Added image type detection.
+ - added smoke test for win32 font bounding_box() method, and
+ fixed the problem reported in ticket #1748.
+ - update t37w32font.t to use i_line() instead of i_draw()
+ - replaced non-portable call to rint() with (int)(dy+0.5) (so we
+ can build on Win32)
+ - the default tifflib warning handler was crashing on Win32
+ under ActivePerl, when an unrecognized tag was read from the
+ file. For now we'll just drop the warnings in the bit bucket.
+ (Ticket #1513)
+ - the code to read multiple tiffs didn't handle files with more
+ than five images correctly, causing a memory overrun.
+ - fix some minor test code hiccups
+ - implemented i_t1_has_chars(), tests for same
+ - added ExistenceTest.{pfb,afm,ttf} for testing $font->has_chars
+ - tests for Imager::Font::Type1::has_chars();
+ - tests for Imager::Font::Truetype::has_chars();
+ - internal and external bounding box calculations now use
+ the same hint flags as text output for Freetype 2.x
+ - made the i_foo_bbox() interface more expandable by using
+ symbolic constants for the sizes and array offsets
+ - added a / character to the ExistenceTest.foo fonts that
+ overlaps the right side of the character cell, to test the
+ advance width reporting.
+ - added advance width to the i_foo_bbox() interface, and
+ implemented it for FT2, FT1 and Type 1
+ - Imager::Font::bounding_box() now returns an Imager::Font::BBox
+ object in scalar context.
+ - implemented $font->align() text output method, for simple output
+ of aligned text
+ - created Imager::Font::Wrap::wrap_text to perform simple text
+ wrapping
+ - FT1, FT2 and T1 fonts now support the face_name method
+ - FT1, FT2 and T1 now support the glyph_names() method
+ - Debian woody supplied FT2.0.9, which didn't support
+ FT_Has_PS_Names(), so we use the FT_HAS_GLYPH_NAMES() macro
+ instead.
+ - some older FT1 don't define TT_MS_LANGID_ENGLISH_GENERAL,
+ which we use, define it if freetype doesn't.
+ - Added extra options to rubthrough() so only a subpart of
+ source image is used.
+ - the image fills didn't handle filling with source images of
+ less than four channels correctly
+ - added comment support the postfix transform2() expression
+ parser
+ - transform2() can now produce images with other than 3 channels.
+ - added a correct T_AVREF input mapping to the typemap to
+ simplify parameter lists
+ - shut off one of the align subtests in the ft2 test. The triggering
+ is likely an ft2 bug.
+ - removed some half written scaling optimization code.
+ - added /sw/lib and /sw/include to the Makefile.PL code for osX.
+ - removed all references to the www.eecs.umich.edu page and changed
+ them to imager.perl.org ones.
+
+0.43

+ reasonable alpha if the input image has no alpha
+ - document the constants that transform2() defines
+ - skip the right number of tests when FT2 isn't available
+ - This version pushed to CPAN because of skip problem in FT2 test.
+
+0.43_01 Fri 8 Oct 2004
+ - only call FT_Get_Postscript_Name() on FT 2.0.6 and later
+ - put the IM_LIBPATH and IM_INCPATH values first in the search
+ path so the builder gets their local versions if desired rather
+ than the system versions they might be trying to avoid
+ - document the exp() and log() transform2() functions
+ - document the constants normally set by transform2().
+ - refer the user to appropriate documents in the example in
+ Imager.pm
+ - change the list of documents in Imager.pm to move the document
+ names out of the =item lines so we can make them into links
+ - the scale() method now produces a warning when called in
+ void context.
+ - font.c now only uses the defined T1Lib error codes
+ - update ppport.h and remove the duplicate definitions from
+ Imager.xs. Had to mangle ppport.h to prevent duplicate global
+ function definitions.
+ - newer versions of tifflib require that all of the function
+ pointers passed to TIFFClientOpen be non-NULL, the mmap() and
+ munmap() pointers were always NULL and the sizeproc was
+ sometimes NULL.
+ - there would be a link or load time error on m_init_log() if
+ Imager was built with IM_NOLOG, fixed by renamed init_log()
+ to m_init_log() in log.c (thanks to Takumi Yamani)
+ - moved some variable definitions to the right place
+ - the Win32 font driver bounding box function now returns the
+ right number of values (both thanks to Takumi Yamani)
+ - the Win32 font driver now uses DEFAULT_CHARSET rather than
+ ANSI_CHARSET are the lfCharSet value for the LOGFONT,
+ as suggested by Takumi Yamani.
+ - fontfiles/ExistenceTest.{pfb,ttf} weren't marked as
+ binary in the CVS repository (caused test failures if you
+ built from CVS on Win32)
+ - Makefile.PL should now handle INCLUDE or LIB with spaces in them
+ correctly on Win32.
+ - the pnm reader read maxval for ppm/pgm files and then ignored it,
+ it's now validated (0 < maxval < 65536) and used to scale
+ samples. Note that binary ppm/pgm files (P6/P5) with maxval >
+ 255 result in an error, since I didn't want to add new features
+ just yet, just get the code that's there working correctly.
+ Thanks to Elthek on rhizo for reporting this and help in
+ tracking it down.
+ Resolves https://rt.cpan.org/Ticket/Display.html?id=7465
+ - added a bunch of tests for reading pnm files.
+ - previously, if you supplied to_paletted and empty color map
+ and set make_colors to 'none', quant_translate() would segfault.
+ This was because it was making the reasonable assumption that
+ you'd have colors to map to. quant_translate() now checks there
+ is at least one color and return NULL if there isn't.
+ - i_img_to_pal() now does error checking of the value returned by
+ quant_translate().
+ - Imager::to_paletted() now checks for success/failure of
+ i_img_to_pal() correctly and does appropriate error handling.
+ - i_writegif_low() did no error checking on the result of
+ quant_translate(), it now does
+ - we now test that trying to write a GIF image with no palette
+ allowable by the quant options is a failure.
+ - Imager::write() was doing nothing with the result of the call
+ to i_writegif_gen(), in particular it wasn't returning () on
+ failure.
+ - added tests for paletted image handling and the methods
+ specific to those images
+ - the XS for i_setcolors() was missing the OUTPUT clause for
+ RETVAL, and hence wasn't returning failure on failure.
+ - supplying a sufficiently small scaling value could make the
+ scale() method return an image with zero height or width.
+ Several of the above together resolve
+ https://rt.cpan.org/Ticket/Display.html?id=7467
+ - the void context warning for scale() now includes the callers
+ filename/line (instead of the default of Imager.pm line 15xx)
+ - Imager->new will now return undef if the dimensions or number of
+ channels specified for an image are out of range. An error
+ message can be retrieved with Imager->errstr.
+ - added the C<builtin> color specifier and the
+ Imager::Color::Table class which defines those colors.
+ Resolves https://rt.cpan.org/Ticket/Display.html?id=2593
+ - added the equals() method to Imager::Color.
+ Resolves https://rt.cpan.org/Ticket/Display.html?id=2238
+ - prevent a test warning introduced by the above
+ - the rotate() and matrix_transform() methods now accept a 'back'
+ parameter specifying a background color. This is only used
+ where there is no source data (think of the corners around an
+ image rotated 45 degrees) and it not combined with transparent
+ pixels from the source image.
+ Resolves https://rt.cpan.org/Ticket/Display.html?id=6140
+ - removed a warning generated by the new matrix_transform() test
+ - added a method index to Imager.pm
+ - corrected "flood fill" to "flood_fill" in Imager/Draw.pod
+ - removed compose() method from Imager/Transformations.pod since
+ it isn't implemented yet
+ - the image resulting from a crop is now the same type as the
+ source image (paletted vs direct, bits/sample)
+ Resolves https://rt.cpan.org/Ticket/Display.html?id=7578
+ - the parameters to crop() weren't handled correctly in most
+ cases other than supplying left,top,right,bottom.
+ - clarified the documentation for crop() providing more detail
+ and more examples
+ - the edges of the cropped area are now cropped against the
+ edges of the source image
+ - cropping to zero width/height is treated as an error (no
+ image is returned and $src->errstr has a message)
+ Resolves https://rt.cpan.org/Ticket/Display.html?id=7581
+ - built 0.43_01 for testing
+
+0.43_02 Mon 26 Oct 2004
+
+- the changes to scale() had some problems with integer vs floating point
+ calculations (only caught in tests under perl 5.8.5 <sigh>)
+- the FT2 glyph_names() method didn't do correct error handling
+ when the string parameter wasn't supplied
+- i_ft2_glyph_name() accepted only an unsigned char as the
+ character code to get the name for, which meant it
+ didn't work for unicode characters \x{100} or above
+- the XS for i_ft2_glyph_name() had a similar problem
+- added NameTest.ttf to be used in checking unicode glyph
+ names
+- added reliable_only optional parameter to the glyph_names()
+ method so you can ignore theresult of FT_Has_PS_Glyph_Names()
+- handle errors given by i_ft2_glyph_name() a bit more
+ correctly
+- the FT1 glyph_names() method didn't do correct error handling
+ when the string parameter wasn't supplied
+- some memory allocated when creating a callback IO object (io_new_cb)
+ wasn't being released (detected with valgrind)
+- the testtools.pl match[nx]() functions escapes the test string on
+ test failure a bit better
+- the XS code for i_tt_glyph_name() used unsigned char to store a
+ unicode character when it should have used unsigned long.
+- the XS code for i_t1_glyph_name() used unsigned char to store a
+ unicode character when it should have used unsigned long.
+- resolves https://rt.cpan.org/Ticket/Display.html?id=7949
+- the type 1 glyph_names() method didn't do correct error handling
+ when the string parameter wasn't supplied
+- renamed io.h to imio.h to prevent problems building under cygwin.
+ resolve https://rt.cpan.org/Ticket/Display.html?id=7948
+- i_writegif_low() wasn't setting the returned global palette, which
+ meant a rubbish palette was returned to the user (detected with valgrind)
+
+0.43_03
+
+- change the "double-include" protection macro that imio.h uses.
+- updated download locations for the various libraries that Imager
+ depends on. Added some advice for cygwin.
+- more information on gif library versions in README and Makefile.PL
+- creating an image where the size of the allocated image buffer would
+ overflow an integer would cause too small a buffer to be allocated.
+ This could potentially be a security hole.
+ partly resolves https://rt.cpan.org/Ticket/Display.html?id=8213
+- set i_format to jpeg for jpeg files and test for it
+- set i_format to png when reading png files and test for it
+- i_yres was being set to the xres when reading a png file
+- added many bad BMP files to test various code paths in bmp.c, and
+ made many minor fixes to bmp.c to make them work:
+ - it was possible for various types of read failures to SEGV, both
+ as NULL pointer dereferences and buffer overflows
+ - some errors, like palettes being too large for the number of bits
+ per pixel, were not being caught
+ - failing to read all of a packed data structure would not cause
+ a read failure
+ - invalid compression types were not always caught
+ - error messages are more consistent (still not always great messages,
+ but one step at a time)
+- added bmp_compression_name, bmp_used_colors, bmp_filesize, bmp_bit_count
+ tags on reading a BMP file
