+ 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, ...)

+
+
+type that describes the format of the data stored in a texture. the name of formats is composed of the following constituents: - multiple channels: - channel (e.g. R, G, B, A or Alpha, Luminance or X (reserved)) - width of the chanel in bit (4, 8, 16, ...) - data type (e.g. ub, us, ui) - number of elements of data types
