Returning an NSRectangle with Equal width and height

Question

I use the following code to return an NSRectangle

  let ciimage = ciImage.cropped(to: $0.bounds.insetBy(dx: -$0.bounds.width/1.6, dy: -$0.bounds.width/1.6) )

But the returned rectangle has unequal width and height.How can i make it a square?

let width = $0.bounds.width; let height = $0.bounds.height
let widthInset = (width > height) ? (width - height) / 2 : 0
let heightInset = (height > width) ? (height - width) / 2 : 0
let croppedBounds = $0.bounds.insetBy(dx: widthInset, dy: heightInset)
ciImage = ciImage.cropped(to: croppedBounds)

Something like that?

Thanks .... but this produces a white border at the bottom of the image. – techno Apr 05 '20 at 13:47
Please take a look at the bottom of this image https://imgur.com/a/FgNcCjv – techno Apr 05 '20 at 13:56
Hmm, it seems like a rounding issue (half-pixel sizes get round up). Also, the image isn't square... – Frank Rupprecht Apr 05 '20 at 13:58
