Hi all, Hope that someone who knows a bit about /src/display/sodipodi-ctrl can help me with these lines:

              for (y = 0; y < side; y++){
                  px = reinterpret_cast<guint32*>(data + y * r);
                  for (x = 0; x < side; x++) {
                      *p++ = *px++;
                  }
              }

The "px++" is not necessary right? Should just be "px" the way I see it.

No, the increment is necesary, because this line is copying an image row by row. Otherwise it would fill p with copies of the first pixel in the row.

The only thing to do here is to perhaps move the declaration of px inside the loop.

Ah, lol, getting late :-) Missed the for loop completely, doh! Thanks for paying attention better than me.

Cheers, Johan
