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:(UI         


        

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);

    // …
}
