Issue with UIImagePickerControllerEditedImage

Question

I need edit my Images before they import to the app but after editing the image reduces some quality how can avoid this ?

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    [self dismissModalViewControllerAnimated:YES];
    imgEdited.image = [info objectForKey:UIImagePickerControllerEditedImage];


}

Answer 1

You can crop UIImagePickerControllerOriginalImage manually by using the value provided via UIImagePickerControllerCropRect.

Untested quick and dirty example:

static UIImage *my_croppedImage(UIImage *image, CGRect cropRect)
{
    UIGraphicsBeginImageContext(cropRect.size);
    [image drawAtPoint:CGPointMake(-cropRect.origin.x, -cropRect.origin.y)];
    UIImage *cropped = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return cropped;
}

- (void) imagePickerController:(UIImagePickerController *)picker
 didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    // …

    UIImage *originalImage = info[UIImagePickerControllerOriginalImage];
    CGRect cropRect = [info[UIImagePickerControllerCropRect] CGRectValue];
    UIImage *croppedImage = my_croppedImage(originalImage, cropRect);

    // …
}    

Answer 2

- (void)imagePickerController:(UIImagePickerController *)picker 
                      didFinishPickingMediaWithInfo:(NSDictionary *)info {

  [picker dismissModalViewControllerAnimated:YES];
  [picker release];

          // Edited image works great (if you allowed editing)
  myUIImageView.image = [info objectForKey:UIImagePickerControllerEditedImage];
          // AND the original image works great
  myUIImageView.image = [info objectForKey:UIImagePickerControllerOriginalImage];
          // AND do whatever you want with it, (NSDictionary *)info is fine now
  UIImage *myImage = [info objectForKey:UIImagePickerControllerEditedImage];
}

You can edit ur image. Try this it may work for your application.Thanks!
