Hi!

I'm not familiar with the GL stuff but i had a chance to do screenshots very easily with a code found on this forum:

UIGraphicsBeginImageContext(self.frame.size);
	[self.window.layer renderInContext:UIGraphicsGetCurrentContext()];
	UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
	UIGraphicsEndImageContext();
	
	UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

My question is, how can I render the drawings of the GLPaint example without the background, just the stroke.
I implemented the code above in the touchEnded method in PaintingView and it works fine, but only renders the background with the segmented bar.

Any ideas please?

Edit: I tried various layers in the red marked code

Edit 2: sry. had no idea whats happening in the first post. Now I have. Thank you for this great example.
