OK - I've just run a test here where a small DiskMemImage is created having 4 tiles, using a DiskMemTileCache that can only hold a single tile in memory. The test gets a Graphics object for the image and draws into each tile in turn It then draws into the tiles again, in the same order as before. This means that each tile will have been flushed to disk with the result of the first draw, then restored to memory to be drawn into again.
The result (just displayed on screen by the test at the moment) looks fine to me. So it seems that a tile remains writable after being disk-cached. I actually thought it would be OK since both DiskMemImage and DiskMemTileCache received a lot of testing by several users when first released. Tomorrow (Sydney time) I'll tidy up the unit test and commit it to the jaitools repo. Meanshile, Akos - I'm not sure I understand your idea about the graphics transformations ? is this something else we can add a test for ?
