1 | This demonstrates the use of PNG_USER_CONFIG, pngusr.h and pngusr.dfa | ||
2 | |||
3 | The makefile builds a minimal read-only decoder with embedded libpng | ||
4 | and zlib. | ||
5 | |||
6 | Specify the location of the zlib source (1.2.1 or later) as ZLIBSRC | ||
7 | on the make command line. | ||

9 | If you prefer to use the shared libraries, go to contrib/pngminus | ||
