The current allowed combinations are: Internal Format External Format Type Bytes per Pixel --------------- --------------- ---- --------------- RGBA RGBA UNSIGNED_BYTE 4 RGB RGB UNSIGNED_BYTE 3 RGBA RGBA UNSIGNED_SHORT_4_4_4_4 2 RGBA RGBA UNSIGNED_SHORT_5_5_5_1 2 RGB RGB UNSIGNED_SHORT_5_6_5 2 LUMINANCE_ALPHA LUMINANCE_ALPHA UNSIGNED_BYTE 2 LUMINANCE LUMINANCE UNSIGNED_BYTE 1 ALPHA ALPHA UNSIGNED_BYTE 1 This table is extended to include format BGRA_EXT and type UNSIGNED_BYTE: Internal Format External Format Type Bytes per Pixel --------------- --------------- ---- --------------- BGRA_EXT BGRA_EXT UNSIGNED_BYTE 4 BGRA8_EXT BGRA_EXT UNSIGNED_BYTE 4 RGBA RGBA UNSIGNED_BYTE 4 RGB RGB UNSIGNED_BYTE 3 RGBA RGBA UNSIGNED_SHORT_4_4_4_4 2 RGBA RGBA UNSIGNED_SHORT_5_5_5_1 2 RGB RGB UNSIGNED_SHORT_5_6_5 2 LUMINANCE_ALPHA LUMINANCE_ALPHA UNSIGNED_BYTE 2 LUMINANCE LUMINANCE UNSIGNED_BYTE 1 ALPHA ALPHA UNSIGNED_BYTE 1 This format is renderable in versions of OpenGL ES from 2.0 onwards.
