Extract barcodes from document Leave feedback
On this page
GroupDocs.Parser provides the functionality to extract barcodes from documents by the getBarcodes() method:
parser.getBarcodes() // returns Iterable<PageBarcodeArea>
This method returns a Java Iterable collection of PageBarcodeArea objects:
| Member | Description |
|---|---|
getPage() | The page that contains the barcode. |
getRectangle() | The rectangular area on the page that contains the barcode. |
getValue() | A string value that represents a value of the barcode page area. |
getCodeTypeName() | A string value that represents a type name of the barcode. |
Here are the steps to extract all barcodes from the whole document:
- Instantiate the
Parserobject for the initial document; - Check if the document supports barcodes extraction;
- Call the
getBarcodes()method and obtain the collection ofPageBarcodeAreaobjects; - Iterate through the collection and get a barcode value.
The following example shows how to extract barcodes from a document:
const groupdocs = require('@groupdocs/groupdocs.parser');
// Create an instance of Parser class
const parser = new groupdocs.Parser('Barcodes.pdf');
try {
// Check if the document supports barcodes extraction
if (!parser.getFeatures().isBarcodes()) {
console.log("Document doesn't support barcodes extraction.");
} else {
// Extract barcodes from the document
const it = parser.getBarcodes().iterator();
// Iterate over barcodes
while (it.hasNext()) {
const barcode = it.next();
// Print the page index
console.log('Page: ' + barcode.getPage().getIndex());
// Print the barcode value
console.log('Value: ' + barcode.getValue());
}
}
} finally {
parser.close();
}
process.exit(0);
The output for Barcodes.pdf:
