Imager release history. Older releases can be found in Changes.old
+General changes:
+
+ - to_paletted() and make_palette() now fail (with an error in
+ errstr()) if invalid quantization parameters are supplied.
+
+ - map() would corrupt a channel if there was a gap in the arrayref of
+ channels. Detected by Coverity. CID 185300.
+
+Coverity finally finished a build[1], fix a few problems:
+
+High severity:
+
+ - reading a color-mapped TGA file with an id string would cause a
+ double-free if the palette was truncated. CID 185317.
+
+ - mixing scaling to sizes where the accumulator row, the working
+ output row or the working input row didn't fit into the address
+ space could result in memory leaks. This can probably only be
+ reproduced on very wide floating-point sample images. CID 185318.
+
+ - convert an array style function parameter pointer to pointer style
+ to prevent confusing Coverity in the T1 bounding box implementation.
+ CID 185343.
+
+ - Similarly in the FT1 bounding box implementation. CID 185338.
+
+ - Similarly for the i_tt_rasterize() function in the FT1
+ implementation. CID 185303.
+
+ - initialize a pointer to prevent Coverity complaining in polygon
+ drawing (it should always end up being set.) CID 185341.
+
+ - addi style makemap could potentially read one past the end of an
+ array. CID 185337.
+
+ - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
+ would result in read beyond the end of the built-in hatch array.
+ Negative values (which Coverity didn't complain about) could also
+ cause problems. CID 185331.
+
+ - the Imager::Color set_internal() interal method no longer
+ calls the over-complicated ICL_set_internal() (which is retained
+ only for the old API.) Coverity complained that this leaked, but
+ this could only occur with an invalid (NULL pointer) color object.
+ CID 185323.
+
+ - the underlying implementation of the map() method could read before
+ the beginning on an allocated array if supplied with inconsistent
+ parameters, which Coverity complained about. No Imager code calls
+ that function with inconsistent parameters, but a
+ belt-and-suspenders check was added. CID 185315.
+
+ - Coverity complained a call to i_getcolors(), used by the
+ implementation of the is_bilevel() method could leave the fetched
+ colors uninitialized. Added a return value check. CID 185308.
+
+ - a numeric combining mode of 13 (eg. as a parameter to
+ Imager::Fill->new())could cause an invalid array read in
+ i_get_combine() due to a fencepost error in validating the combine
+ number. CID 185299.
+
+
+
+ - avoid an unneeded EXTEND() call when the FT1 has_chars()
+ implementation returns 0. CID 185350.
+
+ - avoid accessing a possibly NULL map from MakeMapObject() in a
+ logging call. (GIF) CID 185296.
+
+ - gradgen() allocated the wrong amount of space (always too much) for
+ the color array. CID 185291.
+
+ - avoid dead code in i_tt_glyph_names(). CID 185321.
+
+ - avoid dead code in i_get_anonymous_color_histo(), which is the
+ implementation of getcolorusage(). CID 185327.
+
+ - avoid dead code in i_ft2_glyph_name(), which is the implementation
+ of glyph_names() for FT2. CID 185342.
+
+ - avoid dead code in i_t1_glyph_names(), which is the implementation
+ of glyph_names() for T1. CID 185322.
+
+ - avoid an unneeded EXTEND() call when the FT2 has_chars()
+ implementation returns 0. CID 185292.
+
+ - the unpack code for ICO/CUR file handling could extend 32-bit
+ unsigned values to 64-bit signed. I believe this is harmless. CID
+ 185319.
+
+ - remove an unneeded check when terminating the stream for JPEG
+ writing. CID 185347.
+
+ - skip an unneeded check when freeing the combine temp buffer in the
+ fountain filter. CID 185286.
+
+ - check the combine function pointer consistently rather than the
+ combine code in one place in the fountain filter.
+
+ - error diffusion now validates a custom error diffusion map and reports
+ an error if it's bad. CID 185288.
+
+ - avoid discarding the value of i_io_getc() when scanning numbers in
+ pnm.c. CID 185293.
+
+ - handle failure to clone the log filehandle when cloning the Imager
+ context object on thread creation. CID 185294.
+
+ - fix an unsigned comparison when converting character code to a
+ glyph index with a NULL character map. This should be rare. CID
+ 185297.
+
+ - i_img_info() (C API) no longer tries to handle a NULL image object
+ pointer. CID 185298.
+
+[1] The first two build submissions ended up at the end of a ~400
+build queue, and seemed to have been cancelled by Coverity. A build
+submitted on NYE went through in minutes.
+
+Imager 1.008 - 31 Dec 2018
+============
+
+ - moved EXIF handling from Imager::File::JPEG to core Imager
+ This allows file formats that store EXIF data as blobs similarly
+ to JPEG to re-use this code. (such as Imager::File::WEBP)
+
+ - added some more file extensions to image file type mappings
+
+ - added add_type_extensions() class method
+
+Imager 1.007 - 24 Nov 2018
+============
+
+ - add png_compression_level tag for writing PNG files.
+
+ - avoid flooring a second time in matrix transform interpolation.
+ https://rt.cpan.org/Ticket/Display.html?id=124001
+
+ - produce v2 metadata.
+ Includes change from the ticket and updates to sub-modules.
+ https://rt.cpan.org/Ticket/Display.html?id=127216
+
+ - improve error reporting for the polygon() method
+
+Imager 1.006 - 26 Aug 2017
+============
+
+ - the internal i_errors() function now correctly allocates the stack
+ space needed for its result.
+ https://rt.perl.org/rt3/Ticket/Display.html?id=131938
+
+ - t/100-base/020-color.t now uses Imager::Test's test functions
+ instead of its own.
+ https://rt.cpan.org/Ticket/Display.html?id=111993
+
+ - write_multi() now returns an error result (a false value) if called
+ with a non-(Imager image object). Previously it would typically
+ crash.
+ https://rt.cpan.org/Ticket/Display.html?id=117878
+
+ - improve the documentation of the jpegquality parameter when
+ writing JPEG files.
+
+ - add code to mitigate CVE-2016-1238, Imager will no longer search the
+ default current directory entry in @INC when searching for file
+ format support modules.
+
+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.

- 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 Imager transforms the samples into
- the range 0.0 ... 1.0 which may means the user has to translates
+ the range 0.0 ... 1.0 which may means the user has to translate
the value back.
An untranslated image would be unusable as image data, so
- avoid static variables when capturing IPTC data from JPEG files
- - match Imager::Font;:T1's error message translations to those from
+ - match Imager::Font::T1's error message translations to those from
later versions of T1Lib.
- for libtiff versions that support extended warning handlers (3.8.0
