width=width of the new image (or its frames) height=height of the new image frames= optional number of frames (assumed to be a single frame) |
| Sometimes you want to create a completely new graphic on the fly (using other images, drawing commands, etc.) instead of loading one. This command will let you create a new image with a single frame or multiple frames for animation. You specify the width, height, and optional number of frames. The example should be pretty self-explainatory. |
