Cannot scan vertical barcodes

[vkjrite]

The app in which we have integrated this library is locked in landscape mode.
We have a 1D barcode which is being scanned vertically. This bar code does not get scanned when kept vertically.
But if we rotate the barcode by 90 degrees or make it horizontal then the camera scanner is able to scan it correctly
So my question is -

• can the scanner scan vertical bar codes ?
• Is there a setting that we are missing that we need to set for the vertical and horizontal scans?
