BLIT IMAGE

The “BLITTING” is a data operation used in computer graphics in which several bitmaps are combined into one using a boolean (or mathematical) function. The operation involves at least two bitmaps: a “source” (or “foreground”) and a “destination” (or “background”), and other fields, called “masks” or something like that. The result may be written to a final bitmap, though often it replaces the “destination” field.

To draw, the BLIT IMAGE(S) command will be used. The syntax of this command will be identical to that of PUT IMAGE (therefore with management of images and sequences), with two main differences. The first is the ability to indicate multiple images (separated from each other by a comma) and the second is to be able to indicate which blitting operation you want to use.
