PNMTOPNG / PNGTOPNM
version 2.0, August 1995

The utilities pnmtopng and pngtopnm are based on other pbm tools and
require the libraries included in the pbmplus package. Also required are
the png library and the zlib compression library.

These can be found at:
	ftp://ftp.x.org/R5contrib/netpbm-1mar1994.tar.gz
	ftp://ftp.uu.net/graphics/png/code/libpng-*.zip
	ftp://ftp.uu.net/graphics/png/code/zlib-*.zip

To compile and install a makefile is provided. Do check the directories
where you have put the required libraries.

Note that if you use previous versions of zlib and libpng, you may have to
change the library names in addition to the version numbers. The makefile
assumes that zlib is 0.95 and libpng is 0.80.

For testing purposes, have a look at the test-set png32x32.tar.gz, which
should be available at the same place you found this. It contains for all
PNG color-types a small test-image.
