* Upgraded libpng to version 1.2.15-optipng [private]
* Used a previously-missed RGB-to-palette reduction opportunity
for images containing 256 distinct colors.
* Fixed conversion of bKGD info during rgb-to-palette reductions.
* Fixed pre-computation of iterations.
* Eliminated a false alarm when processing RGB images with tRNS
in Unix-secure mode.
* Fixed behavior of -out and -dir when changing interlacing.
* Fixed behavior of "-dir [DRIVE]:" on Windows.
* Added user options -out and -dir, to specify the name of
the output file or directory.
* Added support for builds based on the system-supplied libpng.
* Upgraded libpng to version 1.2.12-optipng [private]
* Implemented basic support for TIFF (grayscale, RGB and RGBA, uncompressed).
* Avoided the redundant trial when the search space is singular
(e.g. when running "optipng -o1 example.tif").
* Prevented accidental file corruption when using option "-log".
* Fixed (again) a small typo in the online help.
* Implemented bit depth reduction for palette images.
* Upgraded libpng to version 1.2.10-optipng [private]
* Improved the BMP support.
* Added a Unix man page.
* Allowed abbreviation of command-line options.
* Changed user option -log to accept a file name as an argument.
* Changed user option -no to -simulate.
* Fixed an error in handling .bak files on Unix.
* Fixed a small typo in the help screen.
* Added the GUIDE and THANKS documents.
* Converted some text document files to HTML.
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
++ Added pngxtern, a libpng add-on for external image format
support: BMP (uncompressed), GIF, PNM.
(This was incorporated from OptiPNG-Plus.)
++ Implemented RGB(A)-to-palette reductions.
+ If trials are ended prematurely, detailed progression is only
reported under the user option -v.
- Removed reporting of some IDAT sizes that exceeded the optimum.
(This was NOT a bug, but a "feature" that confused some users.)
! Fixed an RGB-to-gray reduction problem that occured under some
specific background colors.
+ Added support for builds based on the system-supplied zlib.
* Modified LICENSE. It is now a verbatim spell of the zlib license.
without losing any information. The idea has been inspired from pngcrush, and
is explained in detail in the PNG-Tech article: "A Guide to PNG optimization"
<http://www.cs.toronto.edu/~cosmin/pngtech/optipng.html>. The implementation
is carried forward in OptiPNG, which offers a faster execution per trial, and
a wider search space.
