I used that trick for almost all graphics in the CODA intro, otherwise it would have not been possible in 64k. |
The chunky compression trick freed almost 7kb.
For coders here some compression stats comparing LZ compression for a detailed pixeled image in planar or 8bit chunky format:
Source:
256 x 224 (5 Planes, interleaved)
Size: 35840 bytes
Doynax compressed
Ratio: 36% reduction
8bit Chunky
Doynax compressed
Ratio: 55% reduction
tldr:
Use 8bit chunky for compressing planar images if you need ~50% better compression ratio. Non interleaved may yield differerent results.
