| Summary: Optimizer for PNG Files that can also insert or delete specified Chunks | |
pngcrush is an excellent batch-mode compression utility for PNG images. Depending on the application that created the original PNGs, it can improve the file size anywhere from a few percent to 40% or more (completely losslessly). The utility also allows specified PNG chunks (e.g. text comments) to be inserted or deleted, and it can fix incorrect gamma info written by Photoshop 5.0 as well as the erroneous iCCP chunk written by Photoshop 5.5.

* Thu Mar 21 2024 Christophe Marin <[email protected]>
- Add patch to fix build with png >= 1.6.42:
* 0001-Check-for-defined-PNG_IGNORE_ADLER32.patch
- Spec cleanup
* Sun Nov 05 2017 [email protected]
- Update to new upstream release 1.8.13:
* Made "-reduce" the default behavior. Removed obsolete options
"-plte_len", "-cc", "-nocc", "-double_gamma", "-already_crushed",
and "-bit_depth".
* Added "-speed" option; it avoids using the AVG or PAETH filters
which are slower to decode.
* Made "-force" force output even when the IDAT is larger, and
added "-noforce" option; "-noforce" is now the default behavior.
* Added "-warn" option, to show only warnings.
* Changed default verbosity from 1 (normal) to 0 (quiet). Use "-v"
to get the previous default behavior and "-v -v" to get the
previous "verbose" behavior. The "-s" (silent) and "-q" (quiet)
options behave as before.
- Remove pngcrush-systemlib.diff: not needed anymore.
- Add package source verification.
* Mon Aug 22 2016 [email protected]
- Add pngcrush-systemlib.diff
Allow building with system libpng where possible, this fixes
build errors on Aarch64 due to incomplete bundled libpng source
- Drop pngcrush-makefile-add-optflags.diff
Supply optflags via CFLAGS, supported by current Makefile
* Sun Jan 17 2016 [email protected]
- Update to new upstream release 1.7.92
* Fixed segfault while writing a -loco MNG
* Eliminated a potential overflow while adding iTXt chunk
* Fixed a double-free bug (CVE-2015-7700). There was a "free" of
the sPLT chunk structure in pngcrush and then again in png.c.
* Increased some buffer sizes in an attempt to prevent possible
overflows.
* Increased maximum size of a text chunk input from 260 to 2048
(STR_BUF_SIZE) bytes, to agree with the help screen
* Fixed bug that caused text chunks after IDAT to be written only
when the "-save" option is used.
* Wed Mar 25 2015 [email protected]
- updated to 1.7.85
- Improved reporting of invalid chunk names. Does not try to put
non-printable characters in STDERR; displays hex numbers instead.
- Fixed include path for utime.h on MSVC (Louis McLaughlin).
- Eliminated "FAR" memory support (it was removed from libpng at version 1.6.0).
- Disabled the "-already_crushed" option which does not really work well.
* Mon Mar 02 2015 [email protected]
- updated to 1.7.84
- pngcrush-1.7.84 fixes more Coverity-scan defects (none are reported
now), so it should be more resistant to crashes due to malformed
input files.
- license adjusted to meet spdx.org, legal says "Zlib"
- run spec-cleaner
* Sat Oct 25 2014 [email protected]
- update to 1.7.78
* Mon Sep 03 2012 [email protected]
