Convert CGPoint from CGRect to other CGRect

Question

I have placed one label on view and view\'s frame is CGRectMake(0,0,270,203). Now I have to take screen shot of view with CGRectMake(0,0,800,600)

Answer 1

You could do something like this:

-(CGPoint) convertPoint: (CGPoint) point fromRect: (CGRect) fromRect toRect: (CGRect) toRect {
    return (CGPoint){
        (toRect.size.width/fromRect.size.width) * point.x,
        (toRect.size.height/fromRect.size.height) * point.y
    };
}
