| Can anyone explain to me what a pixMap is? Or perhaps give me an example of how to use it? |

| Pixmaps provide storage for rectangular regions of pixels. You can create a new pixmap using the CreatePixmap command, or load a pixmap using LoadPixmap. Basically a list in system memory describing each pixel in an image. The image *can* be drawn directly to the backbuffer buit it is slower than drawimage which converts the pixmap to a textured surface kept in video memory. However, with a pixmap, you have access to the pixels so are able to change them. |

| Just tested this. Works really good! Looks like it's still a little slow, but nearly as bad as blitz3d. |

| I hope you're not going to start using them for game sprites...that's what TImage is for. |

| No, I wanted to write a utility that moves parts of the image around. |
