| * will most likely use a color palette. The color appearance |
| 184,11 → 184,19 |
|---|
| * will be pretty random and depend on the default installed |
| * palette. This could be fixed by supporting custom palette |
| * and setting it to simulate the 8-bit truecolor. |
| * |
| * Currently we set the palette on the sparc64 port. |
| * |
| * Note that the byte is being inverted by this function. The reason is |
| * that we would like to use a color palette where the white color code |
| * is 0 and the black color code is 255, as some machines (SunBlade 1500) |
| * use these codes for black and white and prevent to set codes |
| * 0 and 255 to other colors. |
