Hello,

The RPG im working on allows you to draw your own maps. However, im not sure how i can save the drawn picture. Basicly, i think what is needed is a function that allows me to draw ON the image for real. Or make it virtual, and render the lines, then only on save merge the 2. Also, the maps should be small in filesize. Basicly they have to be shared with other players, so i guess its better to use monochrome bitmaps or even a custom format. Any ideas?
