If GL_MAP_COLOR is TRUE, glColorTableEXT scales each color component by the size of lookup table GL_PIXEL_MAP_c_TO_c, then replaces the component by the value that it references in that table; c is R, G, B, or A, respectively. The glColorTableEXT function converts the resulting ...
GL_BGR_EXT provides a format that matches the memory layout of Windows device-independent bitmaps (DIBs). Thus your applications can use the same data with Windows function calls and OpenGL pixel function calls. GL_BGRA_EXT Each pixel is a group of four components in this order: blue, green...
