Reading and decoding PDF-417 barcodes stored in an image or PDF file from within a .NET application

Question

I am looking for a .NET library that is able to decode data from a PDF-417 barcode that is embedded either in an image file or PDF. At this point, I have only been able to find a Java version and a C version.

Ideally, this library would be both open-source and free of charge, but I doubt such a decoder exists.

I am open to trying out demos of existing products that you may have had experience with - which leads me to the question - have you had any experience reading PDF-417 barcodes embedded in images or PDFs using .NET, and which of the available products would you recommend to do so?

Answer 1

We use components (not free) from IDAutomation for PDF417. They are very good. We use them for encoding, as opposed to reading and decoding.

Haven't used this component of theirs, but have a look it is C#, and you can obtain the source code, but again, not free.

Answer 2

try PDF417 encode SDK at http://www.aipsys.com to find another solution.

Answer 3

Aspose has a PDF417 encoder/decoder for both .NET and Java, but it is not open source: http://www.aspose.com/categories/.net-components/aspose.barcode-for-.net/default.aspx

Answer 4

The clear image SDK for .NET is probably the easiest way to decode PDF 417 and many other barcodes. I use it in many projects... although it is not free

         var bitmap = WpfImageHelper.ConvertToBitmap(_BarcodeCam.BitmapSource);

        _ImageEditor.Bitmap = bitmap;
        _ImageEditor.AutoDeskew();
        _ImageEditor.AdvancedBinarize();

        var reader = new BarcodeReader();
        reader.Horizontal = true;
        reader.Vertical = true;
        reader.Pdf417 = true;

        //_ImageEditor.Bitmap.Save("c:\\barcodeimage.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

        var barcodes = reader.Read(_ImageEditor.Bitmap);

        if (barcodes.Count() > 0)

Morovia provides a free pdf417 decoder.
