- Returns the corresponding format.
- auto type() const -> GLenum
- Returns the corresponding pixel data type.
- auto isCompressed() const -> bool
- Returns
trueif the format holds compressed data. - auto numChannels() const -> unsigned int
- Returns the number of color channels.
- void bgrFormat()
- Converts the external format to the corresponding BGR one.
