ios - Image size is taken as (0,0) even though it's not

[ad_1]

I am using GPUImage with Swift 3.0. And I am trying to filter an image but GPUImage crashes saying image size should be more than 0.

My code-

let pixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer)
let ciImage = CIImage(cvPixelBuffer: pixelBuffer!)
var image = UIImage(ciImage: ciImage)

if image.size.height > 0 && image.size.width > 0 
 let contrastfilter = GPUImageContrastFilter()
 image = contrastfilter.image(byFilteringImage: image)

Error-

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException',
reason: 'Passed image must not be empty - it should be at least 1px tall and wide'

Question is-
I have already checked if the height is greater than zero and then only called the function but still, it gives an error.
