1This demonstrates the use of PNG_USER_CONFIG and pngusr.h
2
3The makefile builds a minimal read-only progressive decoder with
4embedded libpng, zlib and your system's X library.
5
6Specify the location of the zlib source (1.2.1 or later) as ZLIBSRC
7on the make command line.
8
9Edit makefile if required, to find your X library and include files,
10then
11
12 make ZLIBSRC=directory
13
14If you prefer to use the shared libraries, go to contrib/gregbook
15and build the rpng2-x application there.
