bounds
Search area in page coordinates. If this value is Empty, then the entire page is searched for barcodes.
maximumBarcodes
Maximum number of barcodes to read. Use -1 to read all barcodes found.
symbologies
Barcode symbologies to search for. If this value is null or an empty array, then all barcode symbologies are searched for.
Array containing the data for each barcode found. An empty array is returned if no barcodes are found on the page.
Refer to BarcodeEngine, BarcodeReader and BarcodeReader.ReadBarcodes for more information on reading barcodes using LEADTOOLS.
This method uses the engine set in DocumentBarcodes.BarcodeEngine. If this value is null then no barcodes are read and this method returns an empty array.
This method calls GetImage and then BarcodeReader.ReadBarcodes to read the barcodes.
Since the search area and options used can differ greatly from one call to the another, the document never saves the barcodes found in the cache. Each call to ReadBarcodes re-reads all the barcodes from the page image.
