    In This Topic

    This demo application is designed as an online barcode recognition web application where you can open your own documents and read several barcode symbologies from them.

    When a barcode is found, a semi-transparent text annotation will be added over the detected barcode with its symbology and its value.

    Symbologies that are recognized are: QR Code, Micro QR Code, PDF417, Datamatrix, Aztec, Code 39, Codeabar, Code 128, Code 93, EAN 8, EAN 13, Patch Code, UPC Version A & E and more. You will find the exhaustive list on GdPicture.NET dedicated website.

    This demo application also demonstrate how to build and use a Custom Snap-In. It is a powerful UI/UX component where you can add your own content and business logic so we took advantage of it to list the available symbologies to detect.
