Precompression Filterhttps://www.w3.org/TR/PNG-Filters.html |
|
Improve the compressibility of your data by filtering it in this way. Improve compression further by arranging data in a way that it precompresses better, too! e.g. rather than do this: For each tile WriteInt(tileType) WriteInt(tileColor) WriteInt(tileSomethingElse) Next where each written int is going to vary widely, Do this: For each tile WriteInt(tileType) Next For each tile WriteInt(tileColor) Next For each tile WriteInt(tileSomethingElse) Next Where each block is going to be full of values with little difference. |

Again, good stuff, Ben. I feel stupid from not considering this sooner.
