Imager release history. Older releases can be found in Changes.old
-Coverity finally finished a build, fix a few problems:
+Imager 1.012 - 14 Jun 2020
+============
+
+ - Imager has moved to github.
+
+ - T1lib support is deprecated
+
+ - added guassian2 filter which allows separate filter radii for vertical
+ and horizontal. Thanks to Leolo.
+ https://rt.cpan.org/Ticket/Display.html?id=129769
+
+ - freetype2 support can now use pkg-config to configure itself.
+
+ - added red, green, blue, alpha methods to color objects.
+
+ - eliminate use vars.
+
+Imager 1.011 - 7 Mar 2019
+============
+
+General changes:
+
+ - correct the type of the data parameter for im_decode_exif().
+
+ - fix the release date listed below for 1.010
+
+ - add missing change entry for RT #128142
+
+ - binmode the correct handle in t/200-file/010-iolayer.t, this may fix some test
+ failures on one CPAN smoker.
+
+ - add the mymeta check (AUTHOR testing only) to MANIFEST
+
+More Coverity fixes:
+
+ - translate_errdiff() could leak memory on failure (introduced in
+ 1.009) CID 185565.
+
+ - i_img_make_palette() could leak memory on failure (introduced in
+ 1.009) CID 185566.
+
+ - DSO_open(), from the original dynamic loading API, could leak
+ dlopen() handles on failure. CID 185309. DSO_close() now releases
+ the memory associated with the internal DSO handle, rather than
+ only releasing the dlopen() handle.
+
+Imager 1.010 - 13 Feb 2019
+============
+
+General changes:
+
+ - added the add_file_magic() class method for adding magic for new
+ file types to Imager's fairly primitive file magic detection.
+
+ - fixed an embarassing documentation typo in Imager::Test.
+
+ - trying to read from a GIF file with no images now sets an error
+ message. Thanks to Peter Sergeant for reporting this.
+ https://rt.cpan.org/Ticket/Display.html?id=128481
+
+ - use undeprecated encoding symbols for FT2. This should fix the
+ build on the badly patched CentOS 7 Freetype 2. Thanks to Slaven
+ Rezic for the report.
+ https://rt.cpan.org/Ticket/Display.html?id=128142
+
+Coverity has come back up read-only, a few more changes:
+
+ - add missing va_end() for bmp.c's write_packed(). CID 185320.
+
+ - similarly for read_packed(). CID 185329.
+
+ - add a NOTREACHED lint comment for pixel_coverage(). Compilers
+ complained about a missing return, Coverity complains about the
+ return. CID 185325.
+
+ - avoid a possible sign extension in imsgi.c. CID 185326.
+
+ - add some FALLTHROUGH lint comments to i_readtga_wiol() where we
+ deliberately fall through switch cases. CID 185328.
+
+ - add assertions in callers to i_new_hatch_low() since Coverity
+ complained about some possible inconsistent NULL checks. CID
+ 185339. I ended up rearranging this function later.
+
+ - remove pointless NULL checks from i_flipxy() and i_img_destroy().
+
+
+Imager 1.009 - 11 Jan 2019
+============
+
+Critical issue:
+
+ - drawing a filled, anti-aliased circle to the left or right of the
+ image (not within the image at all) would cause a buffer overflow.
+ https://rt.cpan.org/Ticket/Display.html?id=128208
+
+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.
+
+ - most numeric parameters to the XS implementation now throw an
+ exception if supplied an unoverloaded reference.
+ https://rt.cpan.org/Ticket/Display.html?id=128208
+
+Coverity finally finished a build[1], fixed several of the problems
+found. Coverity went down before I could finish working through them.
High severity:
i_get_combine() due to a fencepost error in validating the combine
number. CID 185299.
-
+Lower severity (according to Coverity):
- avoid an unneeded EXTEND() call when the FT1 has_chars()
implementation returns 0. CID 185350.
- 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.
- 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 when calculating the glyph
+ for display for FT1. This should be rare. CID 185297.
+
+ - fix a similar bug when calculating whether a glyph is present for
+ has_chars() for FT1. CID 185302.
+
+ - i_img_info() (C API) no longer tries to handle a NULL image object
+ pointer. CID 185298.
+
+ - re-work testing for size_t overflow for circle/random
+ super-sampling for fountain fills. CID 185304.
+
+ - don't check if the unsigned size passed to Imager's malloc wrapper
+ (mymalloc) is negative. Left from when that parameter was signed.
+ CID 185305.
+
+ - make some types larger and add a cast to prevent integer overflows
+ when calculating a palette with median cut for extraordinarily
+ large images. CID 185306.
+
+ - don't check if the unsigned size supplied to
+ im_set_image_file_limits() is negative. CID 185307.
+
+[1] The first two build submissions ended up at the end of a ~400 item
+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
============
- added add_type_extensions() class method
+ - Imager::Files now links to Imager::Install when discussing
+ appropriate libraries.
+ https://rt.cpan.org/Ticket/Display.html?id=127575
+
Imager 1.007 - 24 Nov 2018
============
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
+ - the autolevels filter now works on the luminance of the image
rather then working per channel. The old autolevels filter is
still available as "autolevels_skew".
