Hi @iOSleep , thats very easy:

fileprivate func setupSlider() {
self.angleSlider?.minimumValue = -Float(IGRRadianAngle.toRadians(90))
self.angleSlider?.maximumValue = Float(IGRRadianAngle.toRadians(90))
self.angleSlider?.value = 0.0
}

@IBAction func onChandeAngleSliderValue(_ sender: UISlider) {
let radians: CGFloat = CGFloat(sender.value)
self.changedAngle(value: radians)
}

please see example

...when you rotate to 90/-90, cropMaskView can't change the size.
