Peter,

Were you ever able to figure out why SDL doesn't allow you to get the alpha value on on main surface?

Vielen Dank!

Can you explain what this program is doing and the results it gives?

My question is it possible to set a pixel with a known RGB color and alpha value on the main SDL surface and retrieve the same? I have no problem doing this with a new SDL surface I create.

If you ever figure out how to initialize the main surface so the alpha channel is correctly setup, (like I do when creating a new surface) that would be great and much appreciated.
