Ok ok, sorry for double posting. Honestly I'm thinking I'm trying to do
something that simply isn't possible though.
I'll try my question again. Ok, I have a UIImageView. I am trying to draw a
shadow under the UIImage it holds. Now if I make the UIImageView's bounds some
ungodly size, like the size of the screen it draws shadows perfectly but
obviously this is not acceptable. So I don't understand what I am doing wrong.
I've tried turning off the clipstobounds but that doesn't help unless the
context I am drawing is is clipping in which case I do not know how to turn it
off. But at least in the UIImageView it is not clipping.
So the first question: How do I turn of clipping in the context I'm drawing too?
Second, is the problem something else in my code? Like I said before I get a
perfect shadow unfortunately it is clipped to the edges of the view so it's
useless.
I have tried to enlarge the view by the amount of the offset but this does
nothing except make the view bigger. The image still draws in the same upper
right location rather than the center as I thought I had set it to with the
content mode. I've also tried using the CG draw image method but it draws
upside down and since I don't want to go through flipping the image every time
I add a shadow I gave up on that. It didn't give me any better results though
otherwise I'd have used it. Do I need to do some kind of Affinetransform to
translate the context?
Lastly if I am wasting my time with this please let me know. I've spent hours
now on Google and cannot find any examples of adding a shadow to a UIImage, at
least not this way.
-(void)addShadow:(CGSize)myShadowOffset darkness:(CGFloat)darkness
spread:(CGFloat)spread
{
UIGraphicsBeginImageContext(rotatingView.bounds.size);
CGContextRef myContext = UIGraphicsGetCurrentContext();
float myColorValues[] = {0, 0, 0, darkness};
CGColorRef myColor;
CGColorSpaceRef myColorSpace;
myColorSpace = CGColorSpaceCreateDeviceRGB ();
myColor = CGColorCreate (myColorSpace, myColorValues);
CGContextSetShadowWithColor (myContext, myShadowOffset, spread,
myColor);
[rotatingView.image drawInRect:rotatingView.bounds
blendMode:kCGBlendModeNormal
alpha:1.0];
CGColorRelease (myColor);
CGColorSpaceRelease (myColorSpace);
UIImage *imageCopy = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
rotatingView.image = imageCopy;
