Changes for version 0.45_02
- some test scripts weren't fixing @INC correctly
- t/t101jpeg.t wasn't skipping enough when there was no jpeg support
- bump version to 0.45_02
- For latest versions check the Imager-devel pages: http://imager.perl.org/
Changes for version 0.45_01
- give the colorcount() and maxcolors() methods their own entries and add them to the method index.
- added tiff_bitspersample and tiff_photometric tags to tiff images when read
- loading filter DLLs/DSOs had an off-by-one error allocating a buffer for the filename of the library (does anyone use this functionality?)
- remove old #if 0 code from Imager.xs
- convert t/t15color.t to Test::More
- prevent warnings when looking up a GIMP color with no palette parameter and $ENV{HOME} not set. Resolves: http://rt.cpan.org/NoAuth/Bug.html?id=13143
- added VERSION numbers to most .pms
- convert t/t104ppm.t to Test::More
- convert t/t107bmp.t to Test::More
- convert t/t108tga.t to Test::More
- error messages generated reading JPEG or PNG images are now available via errstr()
- implement/test/document set_file_limits()/get_file_limits() methods, which allow limits on the size of image files read.
- new example for convert() method based on Leolo's query
- implement getscanline(), setscanline() and getsamples() methods. These are low level methods for fast access to image data, based on existing C functions that Imager uses internally.
- limit limits.c to C89
- the gif tests weren't skipping enough when there was no gif support
- move include t1lib out of image.h to font.c, since nothing it provides is needed elsewhere.
- minor POD fixes
- added a brief tutorial
- Imager::Font->new() for the tt (Freetype 1.x) driver now correctly handles errors from i_tt_new(), and passed error messages now generated by i_tt_new(). Resolves: http://rt.cpan.org/NoAuth/Bug.html?id=14804
- renamed lib/Imager/Cookbook.pm to lib/Imager/Cookbook.pod - CPANTS complains about it not having 'use strict;'
- add samples/replace_color.pl
- you can now supply a page parameter to read() to read a given page from a TIFF file.
- added samples/border.pl, and notes on adding a border in Imager::Cookbook.
- added sampled/slant_text.pl, and notes on shearing/rotating text in Imager::Cookbook.
- INCOMPATIBLE CHANGE: reading a gif file will now read the first image from the file rather than the a consolidated image. If you want the old behaviour supply C<< gif_consolidate=>1 >> to the read() method. Older versions of Imager will accept this parameter and produce the same result.
- you can now supply a page parameter to read() to read a given page from a GIF file.
- reading a multi-image GIF was leaking memory (a line buffer per file)
- maxcolors now must be at least 1 when creating a paletted image.
- converted t/t022double.t to use Test::More
- t1 library re-initialization modified to support T1Lib 5.1.0
- setmask() now returns true on success and reports a missing mask parameter.
- double per sample images were ignoring the channel mask.
- converted t/t021sixteen.t to use Test::More
- 16-bit per sample images were ignoring the channel mask
- added t/t91pod.t
- expand Imager::ImageTypes:
- make all methods into =items
- document parameters
- more examples
- add AUTHOR/REVISION/SEE ALSO
- add samples/tk-photo.pl
- fixes to verbose mode in Makefile.PL, also added a -v switch so you can enable it via the command-line Resolves: http://rt.cpan.org/NoAuth/Bug.html?id=16094
- arc(..., fill=> ...) wasn't handling concave areas correctly
- arc(..., color=>...) wasn't properly filling it's area
- added experimental antialiased support to arc()
- the order of the returned values for Imager::Font's align() method was incorrect.
- check the correct directory when adding the cygwin Win32 API include path (Makefile.PL). This was a later response to #16094 Resolves: http://rt.cpan.org/NoAuth/Bug.html?id=16094
- add --nolog command-line switch to Makefile.PL to disable logging
- filled polygons using a complex fill with combine != 0 (none) didn't correctly handle polygons that crossed a given scanline more than once.
- the straight edges of filled arcs weren't being drawn correctly, causing minor artifacts at the inner and external corners
- implemented valign=>'end' for Imager::Font->align
- added $img->align_string() as a way to call Imager::Font->align
- added samples/align-string.pl
- improved missing argument handling a little for the string() method
- linkify Imager.pm a bit more
- expand Imager::Draw:
- make all methods items
- document parameters
- more examples
- add AUTHOR, REVISION.
- add smoke test for nearest_color filter
- added integer overflow checks to many memory allocation calls
- added experimental EXIF decoding when reading JPEG files.
- read/write i_xres, i_yres, i_aspect only tage with JPEG files, and read/write jpeg_density_unit (+_name) tag
- save the jpeg_comment tag when writing
- the has_chars() method now checks the font objects utf8 flag as well as the utf8 parameter.
- clean up Imager::Font documentation:
- string now documented in Imager::Draw
- add parameter list documentation
- document the utf8 parameter for bounding_box(), has_chars() Resolves: http://rt.cpan.org/NoAuth/Bug.html?id=13508
- decode the EXIF GPS IFD as well
- minor documentation touchups
- bump version 0.45_01
