The following example demonstrates Barcode.getAlignment in a practical document-editing workflow. It gets the alignment of the barcode image inside the control.

function onTxError(error) {
    console.error("TX Text Control error:", error.msg);
    error.handled = true;
}

function inspectAlignment(barcode) {
    barcode.getAlignment(
        function(alignment) {
            if (!alignment) {
                console.warn("No barcode alignment was returned.");
                return;
            }
            
            console.log("get alignment result:", alignment);
        },
        onTxError
    );
}
