GroupDocs.Signature provides a powerful engine to search for any digital signatures within PDF files. Java developers can easily enhance their applications with our solution.
// Create an instance of Signature with the document path
final Signature signature = new Signature("input.pdf");
// Instantiate TextSearchOptions to cover all pages
TextSearchOptions options = new TextSearchOptions();
options.setAllPages(true);
// Search for text signatures within the document
List<TextSignature> signatures = signature.search(TextSignature.class, options);
System.out.print("\nSource document contains following text signature(s).");
// List the found signatures for further analysis
for (TextSignature textSignature : signatures) {
System.out.print("Found Text signature at page " + textSignature.getPageNumber()
+ " with type [" + textSignature.getSignatureImplementation() + "] and
text '" + textSignature.getText() + "'.");
}
We are proud to introduce our document signing solution, compatible with all major document formats. Add a wide range of signatures to enhance your documents or secure their content.
Insert digital signatures at any position on any page of a document. Use a variety of signature types, such as text, images, barcodes, metadata, stamps, or digital certificates.
After signing, documents may require further processing. Search for all available signatures, and update or delete them whenever necessary.
Manage hidden metadata embedded in the document. Add new metadata or remove existing entries. Use corporate digital certificates to safeguard the document’s content from unauthorized alterations.
// Pass the source document as a constructor parameter
final Signature signature = new Signature("input.pdf");
// Search for any signatures with a text type
List<ImageSignature> signatures = signature.search(ImageSignature.class, SignatureType.Image);
System.out.print("\nSource document contains following image signature(s).");
// Display the results with the properties of the found signatures
for (ImageSignature imageSignature : signatures)
{
System.out.print("Image signature found at page "+imageSignature.getPageNumber()+
" with size "+imageSignature.getSize()+". Created "+imageSignature.getCreatedOn()+
", modified "+imageSignature.getModifiedOn());
