Imager

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
