It's been a good start into 2011 so far, a brand new chapter about SDL_GFX has been released today on Freepascal meets SDL.
It may sound surprising but native SDL doesn't support rotation and zooming of images in a nice way. Also drawing of primitives (e.g. circles, lines, squares, polygons) isn't supported in a simple way. This gap is closed by Andreas Schiffler's library SDL_GFX which is capable of doing these things properly and more.
The new chapter describes how to compile your own SDL_gfx.dll with the free MinGW C compiler, how to rotate and zoom images, how to draw primitives (including B?©zier curves) and how to setup and use the SDL_GFX framerate manager.
