I am working on a new map and also I have mixed some tilesets I had in the CS2D folder into a big one. Then I saved the big tileset as PNG and went in-game to start mapmaking.
The problem : It takes a bit too long for CS2D to load the PNG tileset and almost 0 seconds to load a BMP tileset.
The PNG tileset helped me with some transparent spots, but if I save to BMP, the transparent spots turn into white or black (this happends if I save it to a 4,8,16,24 - bit image) , if I save the BMP as 32-bit, all tiles turn transparent.
Please explain this thing to me. How I can turn a PNG into BMP, without loss of transparency?
Thank you,
