  24. <p>The glBitmap is a Delphi/FPC unit that contains several wrapper classes to manage OpenGL texture objects. Below you can find a list of the main functionality of this classes: - load texture data from file (e.g. BMP, TGA, DDS, PNG, JPEG, ...) - load texture data from several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface) - save texture data to file (e.g. BMP, TGA, DDS, PNG, JPEG, ...) - save texture data to several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface) - support for many texture formats (e.g. RGB8, BGR8, RGBA8, BGRA8, ...) - manage texture properties (e.g. Filter, Clamp, Mipmap, ...) - upload texture data to video card - download texture data from video card - manipulate texture data (e.g. add alpha, remove alpha, convert to other format, switch RGB, ...)</p>
