I wish I can use gdk_draw_polygon....However I need to plug in my own custom flood fill algorithm. (its actually a texture synthesis method!) I basically need to iterate thorough the pixel array and detect what color the pixel is and decide weather to continue to fill or stop (hit a boundary). I'm just not sure how to detect the color of a pixel on a drawable widget?
