Active Scanning Area

[Gerst20051]

I can't seem to figure out why the barcodes are only scanned when it's in the top half of the camera feed. This is true in portrait and landscape orientation. Is this expected behavior?

The frame of the camera feed takes the bounds of the root view of RSCodeReaderViewController, maybe you should add a print in RSCodeReaderViewController's viewDidLoad()

if let videoPreviewLayer = self.videoPreviewLayer {
    videoPreviewLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
    print(self.view.bounds)
    videoPreviewLayer.frame = self.view.bounds
    self.view.layer.addSublayer(videoPreviewLayer)
}

Hey, I forgot I created this issue but I figured it out. It only scans when it's directly in the center of the screen. I can be anywhere horizontally along the vertical center (equator) of the screen. If you extend the red line all the way to the edges of the screen.

@Gerst20051 how did you get the scanning area guides to display? I would like to add something similar to help users understand the scan area.

The scan area is the horizontal red line. you can create them yourself.
