| 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. |
