Reads the barcodes found on this page.
DocumentPage.prototype.readBarcodes = function(
bounds,
maximumBarcodes,
symbologies
)
readBarcodes(
bounds: LeadRectD,
maximumBarcodes: number,
symbologies: BarcodeSymbology[]
): JQueryPromise<BarcodeData[]>;
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 the barcodes found.
symbologies
Barcode symbologies to search for. If this value is null or an empty array, then all barcode symbologies are searched for.
A Promise object that may resolve successfully to an array of objects of type BarcodeData containing the data for each barcode found. An empty array is returned if no barcodes were found on the page.
This method uses the engine set in the service. If the engine value is null then no barcodes are read and this method returns an empty array.
The readBarcodes 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.
