Image taken in Portrait is distorted when viewed in Landscape

Question

I created a view that has a capture button. When I click on this button, the camera screen opens. but the image taken in Portrait is distorted when viewed in Landscape. How to get the actual image without distortion?

if you are working on ios 5, then you must manually call this function when u capture the image and save it to the photo.

- (UIImage *)fixOrientation : (UIImage *)img { if (img.imageOrientation == UIImageOrientationUp) return img; CGAffineTransform transform = CGAffineTransformIdentity; switch (img.imageOrientation) { case UIImageOrientationDown: case UIImageOrientationDownMirrored: transform = CGAffineTransformTranslate(transform, img.size.width, img.size.height); transform = CGAffineTransformRotate(transform, M_PI); break; case UIImageOrientationLeft: case UIImageOrientationLeftMirrored: transform = CGAffineTransformTranslate(transform, img.size.width, 0); transform = CGAffineTransformRotate(transform, M_PI_2); break; case UIImageOrientationRight: case UIImageOrientationRightMirrored: transform = CGAffineTransformTranslate(transform, 0, img.size.height); transform = CGAffineTransformRotate(transform, -M_PI_2); break; } switch (img.imageOrientation) { case UIImageOrientationUpMirrored: case UIImageOrientationDownMirrored: transform = CGAffineTransformTranslate(transform, img.size.width, 0); transform = CGAffineTransformScale(transform, -1, 1); break; case UIImageOrientationLeftMirrored: case UIImageOrientationRightMirrored: transform = CGAffineTransformTranslate(transform, img.size.height, 0); transform = CGAffineTransformScale(transform, -1, 1); break; } CGContextRef ctx = CGBitmapContextCreate(NULL, img.size.width, img.size.height, CGImageGetBitsPerComponent(img.CGImage), 0, CGImageGetColorSpace(img.CGImage), CGImageGetBitmapInfo(img.CGImage)); CGContextConcatCTM(ctx, transform); switch (img.imageOrientation) { case UIImageOrientationLeft: case UIImageOrientationLeftMirrored: case UIImageOrientationRight: case UIImageOrientationRightMirrored: // Grr... CGContextDrawImage(ctx, CGRectMake(0,0,img.size.height,img.size.width), img.CGImage); break; default: CGContextDrawImage(ctx, CGRectMake(0,0,img.size.width,img.size.height), img.CGImage); break; } CGImageRef cgimg = CGBitmapContextCreateImage(ctx); UIImage *img1 = [UIImage imageWithCGImage:cgimg]; CGContextRelease(ctx); CGImageRelease(cgimg); return img1; } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { self.image = [info objectForKey:UIImagePickerControllerOriginalImage]; snapimage.image = [self fixOrientation:self.image]; } - (void)imagePickerController:(UIImagePickerController *)picker1 didFinishPickingImage:(UIImage *)image1 editingInfo:(NSDictionary *)editingInfo { [picker1 dismissModalViewControllerAnimated:YES]; snapimage.image = [self fixOrientation:image1]; }

You need to adjust the image in landscape orientation to the center of the view, in the shouldAutorotateToInterfaceOrientation method

try like this:

 if(interfaceOrientation == UIInterfaceOrientationLandscapeRight || UIInterfaceOrientationLandscapeLeft) { here customize the rect of your image }
