Package: Direct_Access

Description

package Allegro.Bitmaps.Direct_Access is
The procedures in this package are not part of Allegro but are helper routines for providing direct access to memory bitmaps. Warning: No checking is done for the type of bitmap- it MUST be a memory bitmap- and no bounds checking is done on the pixel coordinates. Be sure you know what you're doing!
