reducing camera roll size
what do i need to put into my code here that will reduce the size of the image I load onto my stage from the camera roll? I change the physical dimensions but its just obviously still loading the larger imagine into the bitmapdata. Im finding if the user loads a huge file it totally crashes the app. I want to reduce it to 1024px on the width

launchCamera()
} else {
// permission denied
}

cameraRoll2.requestPermission();
} catch (e: Error) {
// another request is in progress
}

launchCamera()
}
