| >Get RGBA component values from a pixel stored in the specified pixel format.</P |
| ><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]).</P |
| ><P |
| >If the surface has no alpha component, the alpha will be returned as 0xff |
| (100% opaque).</P |
