- # makefile for PNG (Portable Network Graphics) code.
-
- # This partial makefile compiles the png library for use in the Ghostscript
- # PNG drivers. You can get the source code for this library from:
- # ftp://swrinde.nde.swri.edu/pub/png/src/
- # The makefile is known to work with the following library versions:
- # 0.88, 0.89, 0.90, 0.95, and 0.96. NOTE: the archive for libpng 0.95 may
- # be inconsistent: if you have compilation problems, use an older version.
- # Please see Ghostscript's `make.txt' file for instructions about how to
- # unpack these archives.
- #
- # The specification for the PNG file format is available from:
- # http://www.group42.com/png.htm
- # http://www.w3.org/pub/WWW/TR/WD-png
