Question

In my application I capture image from camera. At that time sharpness of my image is fantastic but with the following lines of code my image is moved to next view.

- (UIImage *) imageFromView:(UIView *)view {

    UIGraphicsBeginImageContext(view.bounds.size);
    [view.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return viewImage;
}

When I see the image in next view at that time it is less sharper than before.

I want to mention, on both screens height and width of image view is same.

then what should be the problem with sharpness of image?

Answer 1

Use this Line

UIGraphicsBeginImageContextWithOptions(view.bounds.size, NO, 0.0);

instead of
UIGraphicsBeginImageContext(view.bounds.size);
