            /*
             If you are reading barcodes from PDF then you may reduce CPU and RAM load using the following approach:
                - instead of using All1D or All2D barcode types, set it to the specific types you have in your documents like PDF417 or Code 39. You may set multiple barcode types if you need to
                - reduce PDF rendering resolution to 200-150 dpi (depends on your document)
                - set specific pages to read barcodes from. If you have barcodes on 2 first pages only then change the code to read barcodes from first 2 pages only.
                - if barcodes are always located / printed in the same corner then also specify the area to read from instead of whole page for scanning
