- Qouting the autodoc for cybergraphics.library:
-
- PURPOSE
- cybergraphics.library is meant to be a gfx board extension for the
- native graphics.library. Because C= never developed a rtg compliant
- graphics.library (up to OS3.1 there are no possibilities to add custom
- boards into the display database in a system friendly fashion), it
- patches some of the original graphics functions in order to integrate
- custom graphics boards into the system.
- It also features some new functions which are not available in the
- standard graphics.library. Currently graphics.library v39 and v40 is
- supported.
- Additionally it is possible to open screens deeper than 256 colours
- which are completely intuition compatible. Nearly every function may
- be used on such screen except some special blits which rely on planar
- bitmap graphics. Also, this screens are 8bit backwards compatible.
- Nearly every standard 8bit application will work on this 15/16/24 bit
- screen. But it only can use the additional features, if it knows of
- CyberGraphX, of course.
- Maybe in a future release of graphics, CyberGraphX will be
- obsolete. But until then, cybergraphics.library is the only way to
- add truecolour features to your application under an intuition
- environment with minimum effort.
- So, CyberGraphX is not meant to be a replacement for the original
- graphics/intuition system (just like EGS is for example), e.g. there
- is no ECS/AGA native chipset CyberGraphX driver, because all the
- functionality of the original chipset is already given in the
- original graphics.library.
- Because of the different goal CyberGraphX spots in comparison to
- EGS for example, it still may lack some features other systems have
- already but it is perhaps the most system friendly graphics extension
- the amiga computer family has seen so far.
-
-
- OVERVIEW
- This part only describes how to use the extended features of
- CyberGraphX. Anything else about programming graphics can be found
- in the original graphics.library documentation.
