Imager-0.44_01

Changes for version 0.44_01

the plugins Makefile has long produced an error after all tests were complete on Win32, finally tracked down why
Makefile.PL now checks the directories specified by $Config{locincpth} and $Config{loclibpth} for includes and libraries respectively. Resolves: https://rt.cpan.org/Ticket/Display.html?id=2942
we were undefing the wrong macro (used as an include guard) when building the error code translation function for freetype 2. This meant most errors came out as numbers.
add a note to the README on how to get font suitcases and dfont files working on OS X.
add dfont to the list of extensions supported by ft2
document Imager::Font->new()'s index parameter
added concept index to Imager.pm's POD
the gradgen filter now does the same color value conversion that Imager's drawing functions do.
added trivial multiple master support via the FT2 driver
added .pcf and .pcf.gz to the list of extensions supported by ft2
the tiff reader now puts warning messages produced during reading into the i_warning tag. Resolves: https://rt.cpan.org/Ticket/Display.html?id=8722
the i_xres and i_yres tags are now stored in a resolution similar to their source. Resolves: https://rt.cpan.org/Ticket/Display.html?id=8520
added tiff_resolutionunit_name tag when reading tiff files
Makefile.PL now attempts to use freetype-config to configure freetype 2 and pkg-config to configure libpng.
avoid complaining about include/lib directories we pull from perl's config or we have built-in
Makefile.PL now builds imconfig.h with #defines for libraries present (and for the GIF library version) rather than putting them into CFLAGS
scanning for required include files is now down by directory rather than by file, using -e to check for the existence for a file rather than doing an eq against every filename in the directory.
previously we only checked a candidate include directory for freetype.h to consider it a valid FT1.x include directory. We now check if it contains fterrors.h too, if it does, then it's from a FT2 installation and we ignore it.
Makefile.PL now accepts command-line options to set include and library directories and to enable/disable drivers.
added simple examples to most of the filters documented in Imager::Filters
explicitly document there are no PNG specific tags.
more examples in Imager::Draw
minor cleanup of Imager::Fill
eliminate unused variables and static functions
simplify some XS code by adding another typemap entry
the right-side bearing used to adjust the final width wasn't being calculated correctly, this would cause the bounding_box() function for freetype 2.x to return a larger than expected text width. http://rt.cpan.org/NoAuth/Bug.html?id=11291
add scaleX/scaleY to the method index and gives them some examples http://rt.cpan.org/NoAuth/Bug.html?id=11328
call read() instead of open() in the example code in Imager.pm, and mention that open() is an alias for read(). http://rt.cpan.org/NoAuth/Bug.html?id=11431
added reference list of crop() parameters. http://rt.cpan.org/NoAuth/Bug.html?id=11430
reading a tga image with an idstring of 128 or more bytes would result in an allocation error, if the platform char type was signed
tests now check that tga tags are set
calling the read() method for a format not included in the Imager build, for example, JPEG with no libjpeg installed, would crash with an undefined function error (modified by DynaLoaders dependence on AutoLoader.) http://rt.cpan.org/NoAuth/Bug.html?id=9618
some test scripts have been modified to use Test::More, which is now included under the t directory. Eventually all will be modified to use Test::More and the duplicates in t/testtools.pl will be removed
the convert, crop, rotate, copy, matrix_transform, to_paletted, to_rgb8, scaleX and scaleY methods now warn when called in void context. http://rt.cpan.org/NoAuth/Bug.html?id=9672
correct email addresses in the README file, and include bug reporting information there too
added README for samples directory, describes interleave.pl and anaglyph.pl to start.
the XS for the internal i_glin() function wasn't copying the pixel values across to the returned color objects. http://rt.cpan.org/NoAuth/Bug.html?id=11860
Imager::Cookbook wasn't included in the MANIFEST
added samp-form.cgi and samp-image.cgi to the samples directory to demonstrate displaying a generated image on a HTML page.
Makefile.PL now adds rules to generate a suitable META.yml to the generated Makefile.
added sample code for handling images uploaded via a HTML form.
saving a GIMP gradiant file with Imager::Fountain->save has always been broken. Fixed it and added tests.
newer versions of GIMP add a line to gradient files before the segment count giving a descriptive name of the gradient. Imager::Fountain can now read and write such gradient files. The interface is a bit indirect, but I'd like to preserve Imager::Fountain as a blessed array ref for now.
the segments parameter supplied to the fountain filter and the fountain fill contructor now accepts color names or other descriptions as other functions do.
fix a few compiler warnings
document the Imager::Font::BBox advance_width() method
Imager::Font::BBox advance_width() method was falling back to the wrong value when the font driver's low level function didn't return the advance width.
the FT 1.x was comparing versus an uninitialized variable when checking the end of string when calculating the right side bearing used to adjust pos_width for glyphs that overlap the right side of the advance width.
Imager::Font::BBox objects now have right_bearing() and display_width() methods. Hopefully this and the advance_width() method fills out the Imager bounding box interface to a useful state. Implemented for all four font drivers.
Win32 font bounding_box() method now supports the advance width and right bearing values.
Imager::Matrix2d->rotate() would only rotate around the supplied centre point if both 'x' and 'y' were non-zero.
the internal i_tags_get_string() function now acts correctly for integer only tags.
the FT1.x driver now supports the align parameter correctly. Tests were added to each driver to check correct handling of the align parameter.
the Win32 font driver bounding_box() method now puts accurate values in the ascent and descent values, previously they were set to the font ascent/descent rather than the values specific to the string.
supplying align=>0 to the win32 font driver string() function now aligns in the same way as the other drivers.
removed the bug reporting email address to prevent spammers stripping it. The URL is still there and if someone knows how rt.cpan.org works they can still figure out the email.
the internal function used to probe file formats if the type parameter wasn't passed to the read() method would produce diagnostics on stdout, precluding use in web applications. Silenced it.
the setcolors() had a fencepost error making it impossible to use it to set the last color in the palette. http://rt.cpan.org/NoAuth/Bug.html?id=12676
fix the filter examples in Imager::Filter so they don't indicate that a new image is returned (the filter() method works in-place)
add examples for the fountain filter
prevent warnings from Makefile.PL when there's no libraries found
Imager no longer assumes that MSVC is the only native Win32 compiler, MinGW can be used to build Imager.
fixed an inverted condition checking the giflib version, and replaced a manual test skip in t/t105gif.t
add tests to exercise hatch fills for floating images. This code is mis-generated with the gcc 4.0 that ships with OS X 10.4
work around junk that pkg-config sends to stderr on FreeBSD 4.10
testimg/base.jpg was missing from the MANIFEST, causing test failures
use a temp file to avoid messing with echo on Win32 when building META.yml
add some Mac OS X notes to the README
