- Get RGB component values from
- a pixel stored in the specified pixel format. <p>
- This function uses the entire
- 8-bit [0..255] range when converting color components from pixel formats with
- less than 8-bits per RGB component (e.g., a completely white pixel in 16-bit
- RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8]).
