Update Barcode signatures in document Leave feedback
GroupDocs.Signature provides BarcodeSignature class to manipulate barcode signatures location, size and textual content.
Please be aware that update method modifies the same document that was passed to constructor of Signature class.
Here are the steps to update Barcode signature in the document with GroupDocs.Signature:
- Create new instance of Signature class and pass source document path as a constructor parameter;
- Instantiate BarcodeSearchOptions object with desired properties;
- Call search method to obtain list of BarcodeSignatures;
- Select from list BarcodeSignature object(s) that should be updated;
- Call Signature object update method and pass one or several signatures to it.
This example shows how to update Barcode signature that was found using search method.
Signature signature = new Signature("sampleSigned.pdf");
try
{
BarcodeSearchOptions options = new BarcodeSearchOptions();
List<BarcodeSignature> signatures = signature.search(BarcodeSignature.class,options);
if (signatures.size() > 0)
{
BarcodeSignature barcodeSignature = signatures.get(0);
barcodeSignature.setLeft(100);
barcodeSignature.setTop(100);
boolean result = signature.update("sampleSigned.pdf",barcodeSignature);
if (result)
{
System.out.print("Signature with Barcode '"+barcodeSignature.getText()+"' and encode type '"+barcodeSignature.getEncodeType().getTypeName()+"' was updated in the document ['"+fileName+"'].");
}
else
{
System.out.print("Signature was not updated in the document! Signature with Barcode"+barcodeSignature.getText()+"' and encode type '"+barcodeSignature.getEncodeType().getTypeName()+"' was not found!");
}
}
} catch (Exception e) {
throw new GroupDocsSignatureException(e.getMessage());
}
