| 10 | .PP |
| 11 | Get RGB component values from a pixel stored in the specified pixel format\&. |
| 12 | .PP |
| 13 | 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])\&. |
