    Hi,

    I’m trying to use Get Barcode in WDG Automation.  It doesn’t error, but it doesn’t return anything for the code of image or the type of barcode.  I’m using a format of All_1D with a source of image.

    Please help!

    Johnathon,

    The trick with the Get Barcode command is to use the Retry mechanism with the proper zoom amount.  My bot will fail to read the barcode with no retry, and it will also fail to read it with too much zoom.  Also, it’s not just with the All_1D; it’s an issue with all types, including QR Codes, which are notoriously easy for most applications to read.

    In the image below, I have Retry turned on, and I’m zooming in 10% each time (Step), until I reach 500% zoom (Max zoom).  If I use a 20% Step it fails.  It’s finicky.  Try playing around with the numbers & let me know what happens.
