View Full Version : Graphics32 1.7 Beta

23-12-2004, 05:39 PM
A beta of the new version of the Graphics32 1.7 library has been released.

Graphics32 is a fast graphics library, optimized for 32-bit pixel formats that provides quick operations with pixels and graphic primitives. It is designed for Delphi and Kylix under CLX. It is not a replacement for OpenGL or DirectX, instead it is a replacement for your standard graphics manipulation objects like TBitmap and TCanvas and in most cases outperforms the standard methods offered by Borland.

You can get more information about Graphics32 at www.graphics32.org/wiki/ ('http://graphics32.org/wiki/')
