Extract barcodes from document page area Leave feedback
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:
| Member | Description |
|---|---|
| Page | The page that contains the text area. |
| Rectangle | The rectangular area on the page that contains the text area. |
| Value | A string value that represents a value of the barcode page area. |
| CodeTypeName | A 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());
}
}
