Export CGPath as JPG or PNG

Question

Is it possible to take a path draw in an UIView with CGPath and export it as a PNG?

Answer 1

Assuming you want a UIImage, not a png file, you can do something like this:

UIGraphicsBeginImageContext(size); 
CGContextRef context = UIGraphicsGetCurrentContext();

CGContextSetRGBStrokeColor(context, 1.0, 0.0, 0.0, 1.0);
CGContextSetLineWidth(context, 2.0);
CGContextSetLineCap(context, kCGLineCapSquare);

//DRAW YOUR PATH HERE

CGContextStrokePath(context);

myUIImage = UIGraphicsGetImageFromCurrentImageContext();
[myUIImage retain];  

UIGraphicsEndImageContext();
