A new function is exported, glCopyTextureCHROMIUM, that performs the same copy operation as glCopyTexImage2D, while respecting the pixel-storage modifiers - UNPACK_FLIP_Y_CHROMIUM and GL_UNPACK_PREMULTIPLY_ALPHA_CHROMIUM. + UNPACK_FLIP_Y_CHROMIUM, GL_UNPACK_PREMULTIPLY_ALPHA_CHROMIUM and + GL_UNPACK_UNPREMULTIPLY_ALPHA_CHROMIUM. + + If GL_UNPACK_PREMULTIPLY_ALPHA_CHROMIUM and + GL_UNPACK_UNPREMULTIPLY_ALPHA_CHROMIUM are enabled. Then no alpha + processing occurs. This is the equivalent of having neither flag set. The extension also supports copying BGRA textures, which is not explicitly granted by EXT_texture_format_BGRA8888. |
