PDF barcode recognition is a great way to identify and categorize a document. Option 2: Use A Document Processing Software With Built-In PDF Barcode Recognition To see all command line parameters of Zbar, have a look at the Zbar Manpage. Without this parameter, more boilerplate information is returned which you might not need. The parameter –raw makes sure that only the values of your barcodes are returned. Just run the following command to scan all barcodes which are located in your image file: Obviously you can also use the command line version of Zbar which is really easy to use. Several wrappers for different programming languages, including C++, Java, Python and Ruby, exist for ZBar and you can easily integrate it in your system. A wide-spread, and probably the best, library to read Barcodes and QR-codes from images is called Zbar. Once you have your PDF document converted to an image file, it’s time for the next step: scan barcodes from an image file. Without this parameter, the resolution of your image will be too low and the barcode scanning will fail. In case you want to work with ImageMagick on the command line, you can convert your PDF documents with the following command:Īdding the parameter -r 150 is important.

ImageMagick is a command line tool which comes with bindings for many programming languages.

What do we do then? Obviously, we don’t want to print the document just be able to scan the barcode with a physical scanner, right?

The difficulty arises when these codes are in PDF or scanned documents that are stored on your computer. Which means printed on a product or a piece of paper. Usually, reading barcodes and QR Codes is simple if they are in the scannable format. Reading Barcodes and QR Codes From PDFs and Images We will also learn about PDF Barcode Scanners and PDF QR Codes Scanner Software. Image files, such as PNG, JPEG, or TIFF format (e.g. In this blog post, we are going to learn the best way to read barcodes and QR codes from PDFs, images, and scanned documents. How do we read barcodes from PDFs? Or how do we read barcodes from already scanned documents in general? However, reading physical barcodes on items is one thing and reading barcodes or QR codes from the PDFs or documents is completely another. After all, just place the barcode or the QR code under the laser or camera-based scanner and your barcode is scanned. In today’s times when almost every single item comes with its own barcode, reading barcodes and QR codes seems to be the simplest thing to do.
