Retargetable graphics

Retargetable graphics (abbreviated as RTG) is a device driver API mainly used by third-party graphics hardware to interface with AmigaOS via a set of libraries. The software libraries may include software tools to adjust resolution, screen colors, pointers, and screenmodes. It will use available hardware and will not extend the capabilities in any way.

The Amiga OS 3.x intuition.library is limited to 8-bit display depths, but RTG libraries make it possible to handle higher depths such as 24 bits; on Amiga there are two common APIs: Picasso 96 and CyberGraphX, which are almost compatible with each other. Both Picasso 96 and CyberGraphX require at least 4 MB RAM and a 68020 CPU to operate.
