Extract barcodes from document page area

GroupDocs.Parser provides the functionality to extract barcodes from documents by the GetBarcodes method:

Iterable<PageBarcodeArea> getBarcodes(PageAreaOptions options)

This method returns a collection of PageBarcodeArea objects:

MemberDescription
PageThe page that contains the text area.
RectangleThe rectangular area on the page that contains the text area.
ValueA string value that represents a value of the barcode page area.
CodeTypeNameA string value than represents a type name of the barcode.

Here are the steps to extract all barcodes from the whole document:

  • Instantiate Parser object for the initial document;
  • Check if the document supports barcodes extraction;
  • Instantiate¬†PageAreaOptions with the rectangular area;
  • Call GetBarcodes method and obtain collection of PageBarcodeArea objects;
  • Iterate through the collection and get a barcode value.

The following example shows how to extract barcodes from the upper-right corner:

// Create an instance of Parser class
try (Parser parser = new Parser(Constants.SamplePdfWithBarcodes)) {
	// Check if the document supports barcodes extraction
	if (!parser.getFeatures().isBarcodes()) {
		System.out.println("Document doesn't support barcodes extraction.");
		return;
	}

	// Create the options which are used for barcodes extraction
	PageAreaOptions options = new PageAreaOptions(new Rectangle(new Point(590, 80), new Size(150, 150)));
	// Extract barcodes from the upper-right corner.
	Iterable<PageBarcodeArea> barcodes = parser.getBarcodes(options);

	// Iterate over barcodes
	for (PageBarcodeArea barcode : barcodes) {
		// Print the page index
		System.out.println("Page: " + barcode.getPage().getIndex());
		// Print the barcode value
		System.out.println("Value: " + barcode.getValue());
	}
}
