How to Convert UIImage to CIImage and vice versa

Question

I\'m trying to get CIImage from ImageView that display on the screen.

UIImage *image = myImageView.image;

convert image

Answer 1

When converting UIImage to CIImage, I had 2 separate cases where it's sometimes nil and sometimes not. Below code solved it:

CIImage *ciImage;
ciImage=[[CIImage alloc] initWithImage:imageToConvert];
if (ciImage==nil)
    ciImage=imageToConvert.CIImage;
