To create an animation bitmap you need to place the different frames in a horizontal layout. Each frame must be the same size. I included the original gears.xcf file which can be edited with 'The Gimp' imaging program. This demo includes two animation examples. gears.bmp - which contains 4 frames with transparency. wanda.bmp - which contains 8 frames and no transparency. Wanda the fish originates from the Gnome project. Regards, - Graeme -
