This command will let you draw a rectangular PORTION of an image to the designated location on the screen. The transparent/masked portions of the original image will be drawn transparent, just as you normally would draw an image. This is handy if you are doing something like revealing part of a screen when the player uncovers something (think QIX). You could load the 'picture' into an image, then when the player clears a rectangular region, you could paste that portion of the final image onto the playfield. If you want to draw the image portion with no transparency or mask, use DrawBlockRect instead. |
