Branch: CURRENT, Version: 1.8.10, Package name: pngcrush-1.8.10, Maintainer: pkgsrc-users

Pngcrush is an optimizer for PNG (Portable Network Graphics) files.
It can be run from the commandline. Its main purpose is to reduce the
size of the PNG IDAT datastream by trying various compression levels
an PNG filter methods. It also can be used to remove unwanted
ancillary chunks, or to add certain chunks including gAMA, tRNS, and
textual chunks.

Pngcrush is open source and may be used by anyone without fee.

The author of pngcrush is Glenn Randers-Pehrson, randeg@alum.rpi.edu

Log message:
Version 1.8.10:
* Changed ADLER32 checksum handling to only use inflateValidate()
  during IDAT chunk handling; it broke iCCP chunk handling.

Log message:
Version 1.8.8 (built with libpng-1.6.26beta06 and zlib-1.2.8.1)
  Fixed "nolib" build (bug report by Hanspeter Niederstrasser).
    Make sure we use system-png.h, and not the local file.  It is now
    possible to build either the regular pngcrush or the "nolib"
    pngcrush in the complete pngcrush source directory (use
    "make clean" before rebuilding!)
  Fixed timing when using "clock()". Sometimes an additional second
    was added when the timer crossed a one-second boundary, since
    version 1.8.5.
  Upgrade libpng to version 1.6.26beta06 and zlib to 1.2.8.1.
  Use zlib-1.2.8.1 new "inflateValidate()" function to avoid checking
    ADLER32 checksums. Version 1.8.7 did not work when the "-fix"
    option was used.

Log message:
Version 1.7.85 (built with libpng-1.6.16 and zlib-1.2.8)
  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.

Log message:
Changes 1.7.73:
* Restored calls to png_set_crc_action() which had been removed from
  version 1.7.72 for some testing and inadvertently not restored.
* Changed "fix" internal variable name to "salvage" (still \ 
set with "-fix")
* Added code to fix/salvage PNG with "bad adaptive filter value" error.
* Avoid calculating CRC during compression trials except for the last trial,
  when the output is actually written.
* Fixed a bug with reducing 16-bit images to 8-bit using "-reduce" option.
