Older releases can be found in Changes.old +Imager 1.005 - 16 Apr 2016 +============ + +It's now been ten years since I switched to the new Changes file in +release 0.55. + + - revert the ivdformat probes, they don't work as is and trying to + fix them is too much work for now. + +Imager 1.004_004 - 15 Apr 2016 +================ + + - test that the ivdformat from Config is correct and look for a valid + one if it isn't. + For the strange Win32 failures. + + - fix a copy and paste error in pod in samples/samp-form.cgi + +Imager 1.004_003 - 23 Mar 2016 +================ + + - add some extra error reporting to the I/O layers tests, this might + help catch a failure seen on Win32. + http://cpantesters.org/cpan/report/99781689-6bf5-1014-897a-75cb4eee1325 + +Imager 1.004_002 - 20 Mar 2016 +================ + + - don't use the seek() method on opened() handles in + t/200-file/400-basic.t. In older versions of perl such handles are + only IO::Handle objects, not IO::File, and don't have a seek() + method. + +Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday) +================ + + - re-work the t/200-file/400-basic.t to correctly handle failures + It's custom ok() function didn't have a prototype and didn't use scalar(). + This caused ok() to use the note instead of the value being tested when + the method called returned an empty list. For an example of the problem + caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093 + + - remove some noise from when Imager tried to work with bugs in old + versions of giflib. I can't do much about the new bugs. + + - the new autolevels filter (Imager 0.99) used an integer for the + sample scaling factor which caused the top output level to be too + low (depending on the scaling required.) It now uses a double. + https://rt.cpan.org/Ticket/Display.html?id=111871 + + - the new autolevels filter had off-by-one errors calculating the + minimum and maximum luminance from the histogram. This slightly + reduced the contrast of the output image. + https://rt.cpan.org/Ticket/Display.html?id=111871 + + - the new autolevels filter now uses a lookup table for 8-bit images + to avoid a floating point multiply for each sample. + https://rt.cpan.org/Ticket/Display.html?id=111871 + + - fixed several memory leaks detected by valgrind: + + - addcolors() leaked the temporary array of colors supplied to the + internal API + + - make_palette() leaked the temporary image array (not the images + themselves) passed to the internal API. + + - combine()/i_combine() leaked its working row buffers + + - getcolorusage()/i_get_anonymous_color_histo() leaked the sample + buffer if there were too many colors + + - getcolorcount()/i_count_colors() leaked the sample buffer if + there were too many colors. + + - the nearest_color filter (undocumented until I find a use for it) + leaked both temporaries passed to the API and internal buffers + + - the internal process of upgrading a paletted image to a direct + color image would leak a context object reference count. + + - a write failure when writing to a GIF file could leak memory. + + - failing to write to a 1-bit/pixel ICO image could leak memory. + + - Imager no longer deliberately leaks the context object from the + initial thread. This was done to ensure there was always a context + object available, but the code that needed that now handles the + lack correctly, + + - fixed some uninitialized memory usage detected by valgrind: + + - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/ + i_matrix_transform_bg() didn't initialize a working color value + if there was zero pixel coverage. + + - i_ft2_cp() didn't initialize the complete color when producing an + intermediate image. This caused uninitialized value usage when + logging the color. + +Imager 1.004 - 8 Nov 2015 +============ + + - Imager::Color::Table is now pre-loaded by the preload() method. + https://rt.cpan.org/Ticket/Display.html?id=104896 + + - fix an assertion triggered under perl 5.23.4. + Thanks to A.

Currently Imager 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 @@ -22,6 +191,9 @@ Imager release history.
