Hmmm... I've run across a problem with the tileset loader I'm working on... My tile reader views an image with the colors RGB 0,0,0 to RGB 0,0,255, to give me 256 possible tiles to load as a map (That's a considerable amount! But they don't ALL have to be used...). While the map loads, however, the user can see the map file for a aecond or two. I don't want this!!! How can I get the screen to be blank ( or at least a small "Loading" image ) without messing up the dbPoint(X,Y) command?!?

Tunnel vision yet? Have a carrot!

Turn on sync and don't call use dbSync() while loading.
Having dbSyncOff causes it to sync on its own at regular intervals.

Also you can paste a sprite (or just an image) over the entire screen while loading, for example a loading animation (in which case you will have to sync to update that, but it will cover whatever is behind it).

You don't need to use dbPoint to read the contents of an image. Convert it to a memblock and then you can read the values of pixels without ever putting the image on the screen. Here is a post which explains the structure of an image memblock. If you type "memblock" into the search field of the Dark GDK help, you will find the commands related to it.

Oh shoot, didn't read your post properly.
Mireben is right and that would be the preferred way of doing it. If you still want to use the dbPoint function you should be able to paste the image either off-screen (ie. at negative coordinates) or to another bitmap (dbCreateBitmap(), dbSetCurrentBitmap()). Point is way slower than memblocks though
