Part of the iPhone General/UIKit framework.
Instatiates the image from the application directory.
- (void)compositeToPoint:(General/CGPoint)p operation:(int)operation;
Composites the image into the current drawing context. Is operation same as General/NSCompositingOperation?
I’ve been trying to find out how to draw an General/UIImage rotated 90�/-90�, but since you can’t use (i think) General/AppKit you can’t use whole of General/NSAffineTransform which makes it difficult. Any ideas on how to draw an General/UIImage rotated?
I think you should be able to just go down into General/CoreGraphics and do this: http://developer.apple.com/documentation/General/GraphicsImaging/Reference/General/CGAffineTransform/Reference/reference.html
Prolly not the answer you were looking for, but that’s about the only thing I can come up with.
The simplest method to rotate a General/UIImage is to use a General/CGAffineTransform and rotate its view. The nice thing is on the iPhone OS there are some convenience methods to do this, so the result looks something like this:
General/CGAffineTransform rotate = General/CGAffineTransformMakeRotation(1.57079633); [myImageView setTransform:rotate];
The General/CGAffineTransformMakeRotation takes a float in radians, so this example will rotate the image 90˚ clockwise.
Better to use M_PI_2, no?
