| // by alex evans, 2011. released into the public domain. | |
| // based on a first ever reading of the png spec, it occurs to me that a minimal png encoder should be quite simple. | |
| // this is a first stab - may be buggy! the only external dependency is zlib and some basic typedefs (u32, u8) | |
| // | |
| // VERSION 0.02! now using zlib's crc rather than my own, and avoiding a memcpy and memory scribbler in the old one | |
| // by passing the zero byte at the start of the scanline to zlib first, then the original scanline in place. WIN! | |
