| This demonstrates the use of PNG_USER_CONFIG and pngusr.h | |
| To build a minimal write-only encoder with embedded libpng and zlib, run | |
| gather.sh # to collect needed files from pngminus, libpng, and zlib | |
| make | |
| If you prefer to use the shared libraries, go to contrib/pngminus | |
| and build the pnm2png application there. |
