Dear Chris,

I just tried the new version you sent me. It works perfectly, thank you so much. Will this be in an upcoming release of MRICroGL?
- Images are in native resolution
- BMPZOOM scales them correctly, no black bars any more!
- SHARPEN works in a script
- The exported pngs look much crisper, even without sharpen!
- Retina-Display option does not alter the images (I guess because I don't have a retina screen :-))

All the best, and thank you again, this boosts my workflow,
Lars
