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