image mirrored and turned after takeing from cam

[robin1508]

Hi guys,

I have a kind of funny problem..

What my program does:
first I can take a pic with the camera --> then it gets gropped --> after that it sould be displayed correctly on a UIImageView

The problem is that the image displayed on the imageview is mirrored and turned.. I dont know why but I hope someone does ^^

If I delete the part where it gets cropped, the image gets displayed correctly on the imageview. It seems that my cropping method is turning the image around.
Here is my code:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
	[self.view addSubview:mainView];
	
	UIImage *camImage = [info objectForKey:UIImagePickerControllerOriginalImage];	
	
	UIImage *croppedImage = [self imageByCropping:camImage toRect:CGRectMake(1, 1,150, 160)];
	
	[mainView.imageView setImage:croppedImage];
	
	
	NSLog([NSString stringWithFormat:@"%f°", croppedImage.size.height]);
	//NSLog("Cropped Image size y %.02f", croppedImage.size.height);
	
	[[picker parentViewController] dismissModalViewControllerAnimated:YES];
	
	//[croppedImage release];
	//[camImage release];
	
}



- (UIImage*)imageByCropping:(UIImage *)imageToCrop toRect:(CGRect)rect	{
	
	
	
	
	UIGraphicsBeginImageContext(rect.size);
	
	CGContextRef currentContext = UIGraphicsGetCurrentContext();

	CGRect clippedRect = CGRectMake(0, 0, rect.size.width, rect.size.height);
	CGContextClipToRect( currentContext, clippedRect);

	CGRect drawRect = CGRectMake(rect.origin.x,
								 rect.origin.y,
								 imageToCrop.size.width,
								 imageToCrop.size.height);
	
	CGContextDrawImage(currentContext, drawRect, imageToCrop.CGImage);

	UIImage *cropped = UIGraphicsGetImageFromCurrentImageContext();

	UIGraphicsEndImageContext();

	return cropped;
	[cropped release];
	//CGContextRelease(currentContext);
	 
	 
}

I took two screenshots so that you can get into my problem..

Thats the cam view, exactly this pic will be shot by the camera:



With the cropping method, the imageview looks like that:



Without cropping:




By the way, do you see the little black gap between the cameraview an the black toolbar?
How can i get that away?

You may excuse any mistakes in my english language..


Thanx,
