Graphics Intrinsics 110- 139

GRAPHIC INTRINSICS. The follow intrinsics provide a device independent method of accessing graphic functions on the computer. Here are the general concepts:

a. Bitmaps are allocated and defined by handles which uniquely identify individual bitmaps.

b. The Screen is also treated as a bitmap, so all graphics routines work on both the screen and bitmaps. The screen is identified by the unique handle of -1.

c. All bitmaps are 32-bits per pixel, RGB images. XPL supports special RGB modes make them compatible with pervious VGA color palettes and versions of XPL.
