Is it possible to optimize the tiles using pngquant? Example: I create a PNG atlas and the output is about 120 MB. After calling "pngquant 15 -v --nofs --speed 1 map.png" the whole thing shrinks to 15 MB - even though the resolution is >10000 px per edge. Apparently the tiles are saved with 24 bit true color - which certainly makes sense for aerial images, but for a map I would like to limit the number of colors to a reasonable palette size. Does anyone have an idea how I could unleash pngquant on...
