- 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().
-
-0.44
- refer the user to appropriate documents in the example in
Imager.pm
- change the list of documents in Imager.pm to move the document
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.

- 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)
+- 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
