Older releases can be found in Changes.old -Imager 0.96_01 - 1 Jun 2013 +Imager 1.002 - 3 Apr 2015 +============ + + - drawing anti-aliased filled circles is now 10 to 50 times faster + depending on the size of the circle. + https://rt.cpan.org/Ticket/Display.html?id=101682 + + - enhancements to polygon filling: + + - added a mode parameter to control how overlapping regions behave + + - added a polypolygon() method to fill more than one polygon at a + time + + - polygon filling is now exposed through the API. + + - added colormodel(), alphachannel() and colorchannels() methods. + These were added for two reasons: + + - a future version of Imager may allow the number of channels in + an image to not directly represent the color model of an image. + eg. a greyscale TIFF image with multiple alpha channels. + + - a future version of Imager may allow an image to be read without + translation, for example a TIFF file that contains measurements + from an instrument. Currently Image transforms the samples into + the range 0.0 ... 1.0 which may means the user has to translates + the value back. + + An untranslated image would be unusable as image data, so + colormodel() would return "unknown" in this case. + + Similarly a CMYK image might be returned as an "unknown" color + model image, if the caller chooses to disable translation to + RGB. + +Imager 1.001 - 2 Jan 2015 +============ + + - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict + Thanks to Slaven Rezic for the report and the patch. + https://rt.cpan.org/Public/Bug/Display.html?id=98234 + + - GIF: clean-up a test file if the test for the giflib 4.2.0 file + version bug fails. + + - fix Imager::Matrix2d::rotate()'s centre point handling + https://rt.cpan.org/Public/Bug/Display.html?id=99959 + + - ICO: don't apply the icon mask to images with an alpha channel by + default + https://rt.cpan.org/Public/Bug/Display.html?id=99507 + + - make verbose probing output more verbose + + - use Imager::Probe to probe for freetype 1.x + https://rt.cpan.org/Ticket/Display.html?id=100502 + + - The --enable and --disable parameters to the top-level Makefile.PL + work again. + + - update the bundled/modified Devel::CheckLib to handle the gcc-4 + symlink on Cygwin + +Imager 1.000 - 28 Jul 2014 +============ + +There's nothing special about Imager 1.000, it's just another release. + + - fix the skip check for the iolayer qr// buffer test + + - improve error reporting for the iolayer test failing on a small + number of Win32 CPAN testers + +Imager 0.99_02 - 21 Jul 2014 +============== + + - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize + the blue channel in the generated palette, and allow each color + component to be in the range 100..255 instead of just 100..254. + Thanks to Ralf Neubauer. + https://rt.cpan.org/Ticket/Display.html?id=97086 + + - revert "improved the XS for i_io_read() and i_io_raw_read()" + This caused problems with older perls and didn't provide much of a + performance improvement. + + - support Inline 0.57 and later. + Inline 0.57 changed the "with" interface. + https://rt.cpan.org/Ticket/Display.html?id=97108 + + - don't define our own MAXINT macro, it conflicts with windows header + files and in a few places it was the wrong value to use anyway. + https://rt.cpan.org/Ticket/Display.html?id=96425 + +Imager 0.99_01 - 29 Jun 2014 +============== + + - GIF: add support for giflib 5.1.0, which added error code pointer + parameters to EGifCloseFile() and DGifCloseFile(). + https://rt.cpan.org/Ticket/Display.html?id=96756 + + - GIF: avoid a double-free when do_write() fails. + + - fix SV type probing to work on perl before 5.12. Broken in 0.99. + https://rt.cpan.org/Ticket/Display.html?id=96761 + + - PNG: skip the benign error test before libpng 1.6.0, since the + error we're testing didn't exist before 1.6.0. + https://rt.cpan.org/Ticket/Display.html?id=94717 (continued) + +Imager 0.99 - 25 Jun 2014 +=========== + + - Imager::IO->new_buffer() (and hence Imager->read()'s data + parameter) now accepts a reference to a scalar as well as just a + plain scalar. + https://rt.cpan.org/Ticket/Display.html?id=92785 + + - Imager::IO->new_buffer() now always makes a copy of the passed in + buffer to avoid problems with temporary objects used for the return + value of SvPVbyte(). + https://rt.cpan.org/Ticket/Display.html?id=92785 + + - improved the XS for i_io_read() and i_io_raw_read() + https://rt.cpan.org/Ticket/Display.html?id=92738 + + - load plugins from absolute paths on Android + Thanks to Brian Fraser. + https://rt.cpan.org/Ticket/Display.html?id=93272 + + - added the jpeg_optimize parameter for writing JPEG files. This can + significantly reduce file sizes, but uses more memory and time. + https://rt.cpan.org/Ticket/Display.html?id=94292 + + - the autolevels filter now works on the luminosity of the image + rather then working per channel. The old autolevels filter is + still available as "autolevels_skew". + https://rt.cpan.org/Ticket/Display.html?id=94413 + + - Imager::File::PNG now supports libpng 1.6.10. + 1.6.10 changed CRC errors from benign errors to normal errors, + which broke the test which used CRC errors to check for benign + error support. Switched to using a 1-bit grey-scale image with a + palette to test for benign errors. + https://rt.cpan.org/Ticket/Display.html?id=94717 + +Imager 0.98 - 3 Jan 2014 +=========== + +Incompatible changes: + + - the return value of setpixel() has changed. + + Previously the return values for undrawable pixels vs caller errors + changed depending on whether you used the multiple pixel calling + mechanism, or the single pixel mechanism. + + Now: + + - for an invalid parameter, such as an unknown colour, or missing + parameter, an empty list (or undef in scalar context) is + returned, and errstr() is set, + + - otherwise the number of pixels drawn is returned. If none of + the pixels could be drawn (they were all outside the image), "0 + but true" is returned. + + https://rt.cpan.org/Ticket/Display.html?id=87650 + +Other changes: + + - when drawing on an image with an alpha channel where the source + minimum is greater than zero, Imager would read from beyond the end + of a malloc() allocated buffer. In rare circumstances this could + lead to some of the source image not being written to the target + image, or possibly to a segmentation fault. + I don't believe this has any security concerns beyond that. + + - if the first text drawn with Imager::Font::T1 is not anti-aliased, + text drawn would be nonsense. This would also read beyond the end + of a malloced buffer. + + - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be + truncated early. + https://rt.cpan.org/Ticket/Display.html?id=88993 + + - Imager::Font::Wrap no longer requires the image parameter. + https://rt.cpan.org/Ticket/Display.html?id=87338 + + - a documentation typo fix in Imager::Transformations + Thanks to Adrian Yee. + https://rt.cpan.org/Ticket/Display.html?id=88598 + + - Image::Probe, Imager's internal module for probing library + locations now searches the directories specified by LD_RUN_PATH, + LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries, + and the corresponing s/\blib$/include/ directories for header + files. + https://rt.cpan.org/Ticket/Display.html?id=86428 + +Imager 0.97 - 15 Jul 2013 +=========== + +No changes from 0.96_02. + +Imager 0.96_02 - 8 Jul 2013 +============== + + - PNG: treat a version mismatch between headers and library as a + probe failure. + https://rt.cpan.org/Ticket/Display.html?id=86659 + + - PNG: the check for benign error support is more complex than a + simple library version check, check for the appropriate macro. + Thanks for Slaven Rezic for following up on my CPAN Testers result + queries. + https://rt.cpan.org/Ticket/Display.html?id=86659 + + - W32: add a missing head1 AUTHORS to the old Win32.pm + https://rt.cpan.org/Ticket/Display.html?id=86658 + +Imager 0.96_01 - 1 Jul 2013 ============== - TIFF: handle SampleFormat = 2 by translating the signed integer
