Has anyone had any success reading barcodes from PDFs or images in a Cache/IRIS application? I've been looking at some possible solutions for this, including the open source ZXing libraries. I know we have the ability to create them in Zen and Intersystems Reports, but as far as I know, there's nothing built in to actually read data from a barcode. If anyone has suggestions on how to go about this, I'd love to hear them.
