I've created an example app with fake drivers license images, and my implementation of this library. I have also played around a bit with changing the images to greyscale and decreasing the brightness too, but no luck getting this to work. I have ran these same barcode images through the zxing cli tool and it detects and decodes them with no issues. However even though the images seem like great quality to me and scans perfectly with browser/phone based barcode scanners, this javascript implementation of zxing wont detect or decode the barcodes. I've got the library working and done lots of tests with various pdf417 barcode images from a bunch of drivers licenses for an app im trying to build. I'm wondering if anyone has had this same issue when trying to use this library for scanning PDF417 barcodes from images in nodejs.
