This library is intended to make it easy to perform blt operations on a GOP framebuffer without using the GOP Blt function. There can be two main forms of implementations of this library: 1) A library which interfaces directly with a framebuffer, and has no dependence on the GOP protocol. Once configured with the framebuffer parameters, it can operate directly on the framebuffer. 2) A library which interfaces with the GOP protocol. In this case this library provides a convenience layer and allows blt code to look cleaner. Potential uses for this library: * Video driver with a framebuffer will not need to implement GOP Blt function itself. Instead it can utilize an implementation of this library as described in #1 above. * OS Loader code which would like to easily use the GOP framebuffer after Exit Boot Services. This would use a library instance as described in #1 above. * Any other code which would like to call GOP blt, but simplify the code with the more convenient functions provided by this library interface. (Using a library as described in #2 above.) git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11520 6f19259b-4bc3-4df7-8a09-765794883524 |
