!!DESCRIPTION |

| |
|
24 |
Get RGBA component values from a pixel stored in the |
| |
|
25 |
specified pixel format. |
| |
|

|

|

This function uses the entire 8-bit [[0..255] range when |
| |
|
29 |
converting color components from pixel formats with less |
| |
|
30 |
than 8-bits per RGB component (e.g., a completely white |
| |
|
31 |
pixel in 16-bit RGB565 format would return [[0xff, 0xff, |
| |
|
32 |
0xff] not [[0xf8, 0xfc, 0xf8]). |
| |
|
33 |
|
| |
|
34 |
|
| |
|
35 |
If the surface has no alpha component, the alpha will be |
| |
|
36 |
returned as 0xff (100% opaque). |
