Search area in page coordinates. If this value is Empty, then the whole page is searched for barcodes.

Barcode symbologies to search for. If this value is null or an empty array, then all barcode symbologies are used.
This method uses the engine set in the service. If this value is null then no barcodes are read and this method will return an empty array.
This method calls getImageUrl and then reads the barcodes found.
Since the search area and options used can differ greatly from one call to the another, the document will never save the barcodes found in the cache. Each call to ReadBarcodes will re-read all the barcodes from the page image.
For an example, refer to DocumentBarcodes.
