GroupDocs.Signature makes it easy for Java developers to delete e-signatures in PDF files using their applications by following a few simple steps.
// Pass the document containing the signatures to be deleted to Signature
Signature signature = new Signature("input.pdf");
// Retrieve the digital signatures present in the document
DigitalSearchOptions options = new DigitalSearchOptions();
List<DigitalSignature> signatures = signature.search(DigitalSignature.class, options);
// Delete the first located digital signature
if(signatures.size() > 0)
{
DigitalSignature digitalSignature = signatures.get(0);
boolean result = signature.delete("output.pdf", digitalSignature);
// Process the result of the deletion
if(result)
{
System.out.print("\nDigital PDF signature was deleted successfully");
}
}
GroupDocs.Signature for Java is designed for signing and managing business file formats, allowing you to add, modify, verify, or delete signatures as needed.
Easily add text, image, barcode, QR code, or stamp signatures to any page of supported documents. Utilize hidden metadata like EXIF in images or secure document content from unauthorized modifications with digital certificates.
Maximize the potential of signed documents by verifying signatures to ensure their validity. You can also retrieve a comprehensive list of all signatures within a document through a simple search.
Most previously added signatures can be adjusted. You can easily modify text, reposition the signature, or change its color.
Our solution fully supports CRUD operations for signatures, allowing you to delete various types of signatures from a document as needed.
// Provide a document that contains barcode signatures
Signature signature = new Signature("input.pdf");
// Delete all barcode signatures
DeleteResult result = signature.delete("output.pdf", SignatureType.Barcode);
// Process the result of the deletion
if (result.getSucceeded().size() > 0)
{
System.out.print("\nFollowing PDF barcode signatures were deleted:");
int number = 1;
for (BaseSignature temp : result.getSucceeded())
{
System.out.print("Signature #"+number++ +
": Type: "+temp.getSignatureType()+" Id:"+temp.getSignatureId()+
", Text: "+((BarcodeSignature)temp).getText());
}
}
