Changing bounds origin of UIView has no effect

Question

I try to pan/scroll a big image(500x500) in a small frame (200,200) like in Google Maps. Changing bounds origin of UIImageView has no effect. The same part of image is displayed by the view.
IBOutlet UIImageView *image;
-(void)touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event
CGRect bounds=[image bounds];
bounds.origin.x=bounds.origin.x+10;
bounds.origin.y=bounds.origin.y+10;
[image setBounds:bounds];
Does anyone have any idea what is wrong?

Ok, I found out what's wrong.
To "pan" an image you have to change bounds origin of PARENT view.
- (void)applicationDidFinishLaunching:(UIApplication *)application {
CGRect viewRect = CGRectMake(50, 50, 100, 100);
UIView* myView = [self createView:viewRect withColor:[UIColor redColor]];
UIView* childView = [self createView:CGRectMake(0, 0, 50, 50) withColor:[UIColor blueColor]];
[myView addSubview:childView];
[window addSubview:myView];
myView.clipsToBounds=TRUE;
myView.bounds=CGRectMake(45, 45, 100, 100);
[myView release];
[childView release];
[window makeKeyAndVisible];
-(UIView*) createView:(CGRect)viewRect withColor:(UIColor*)color
UIView* myView = [[UIView alloc] initWithFrame:viewRect];
myView.backgroundColor=color;
return myView;
}
