+ - 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

+ - 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

+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)
+- built 0.43_02 for testing
+
+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
+- added tools/imager to the distribution. This is still very
+ experimental and untested. Patches welcome, if you write tests to go
+ with them.
+- the BMP reader now validates the bfOffBits value from the BMP header
+ and skips to that offset before reading image data. Previously this
+ value was read but otherwise ignored.
+- added --palette action to tools/imager
+- i_img_pal_new() now releases the image object memory if creation
+ fails.
+- set i_format to gif when reading gif files and test for it
+- set i_format to pnm when reading pnm files and test for it
+- set i_format to tga when reading tga files and test for it
+- handle image creation failures when reading tga files
+- set i_format to tiff when reading tiff images and test for it
+- handle image creation failures when reading tiff files
+- test t/t35ttfont.t no longer requires TTFONTTEST to be set (and
+ hasn't for a long time,) removed that requirement from README
+- updated home page URLs throughout the .pods
+- added information on reporting bugs to the SUPPORT section of Imager.pm
+- regops.perl now sorts the dumped data structure to produce minimal diffs
+- quant.c now checks for integer overflow allocating its image data
+- i_readraw_wiol() now checks for image creation failure
+- i_readrgb_wiol() now checks for image creation failure
+- i_writergb_wiol() was an empty stub, it now pushes an error message
+ and explicitly returns failure.
+- i_readrgb_wiol() now sets i_format to rgb.
+- set i_format to raw when reading tga files and test for it
+- document i_format tag
+- some tests were using $Config{ivsize} when they should have been
+ using $Config{intsize}
+ Resolves: https://rt.cpan.org/Ticket/Display.html?id=8645
+- tools/imager has been removed from the MANIFEST, it's way too late
+ to test/debug for 0.44.
+- image.h had no prototype for i_ft2_bbox_r() and it was being called
+ from Imager.xs
+- giflib 4.1.3 still doesn't have all the bugs fixed, update the notes
+ in README and in the buggy_giflib.txt file that t105gif.t produces
