This more a question than a suggestion.
If you use drawpicture, you can scale one picture as it's drawn onto
another.
Perhaps, if you inverted the source range (x1>x1 or y1>y2) you would
get an inverted image?
Drawpicture shoould be much faster than going thru pixel-by-pixel.
Does this work?

Hi,
Okay, I have a thread that reverses an image. Heres the code:
for i=0 to p.width-1
for j=0 to p.height-1
c=r1.pixel(i,j)
r2.pixel(i,j)=rgb(255-c.red,255-c.green,255-c.blue)
progress.prog.value=progress.prog.value+1
next
progress.prog.value=progress.prog.value+1
next
The problem is, that takes over 8 seconds. Other programs, such as
Seashore, do it instantly. I'm using RGBSurfaces, which is supposed
to be faster, but is there a faster way? I'm on RB 5.2.4, Mac OS X
10.4.3. Thanks,
