Barcode Processing with the Document Library


The Document library supports searching for and reading the data of all barcodes found on a DocumentPage.

To do so, call DocumentPage.ReadBarcodes to search for and read the data of any barcode found on the page. Different parameters allow you to specify the area of the page to search (or search the entire page), the number of barcodes to read (or read all barcodes), and the barcode symbologies to read (or read all symbologies). DocumentPage.ReadBarcodes calls DocumentPage.getImageUrl and then reads the barcodes found.

DocumentPage.ReadBarcodes returns an array of BarcodeData objects containing the bounding rectangle, data, and type (symbology) for each barcode found. An empty array is returned if no barcodes are found.
