 |
|
| When using GuCopyImage(), can the source and destination overlap if the destination's address is greater than the sources? In theory this should work, aslong as there are nospecial checks for an overlap, or something I'm missing. I'm not at a point where it'd be easy for me to test yet, getting there, but thought I'd ask for now, anyway. |

I think you meant "if the destination's address is lower", because else you will always overwrite source pixels which were not yet copied and thus the copy will produce false results.
And yes, it works. |
