Delete Text signatures from documents
GroupDocs.Signature provides TextSignature class to manipulate text signatures and delete them from the documents.
Please be aware that delete method modifies the same document that was passed to constructor of Signature class.
Here are the steps to delete Text signature from the document with GroupDocs.Signature:
- Create new instance of Signature class and pass source document path as a constructor parameter;
- Instantiate TextSearchOptions object with desired properties;
- Call search method to obtain list of TextSignatures;
- Select from list TextSignature object(s) that should be removed from the document;
- Call Signature object delete method and pass one or several signatures to it.
This example shows how to delete Text signature that was found using search method.
Signature signature = new Signature("signed.pptx");
try
{
TextSearchOptions options = new TextSearchOptions();
// search for text signatures in document
List<TextSignature> signatures = signature.search(TextSignature.class,options);
if(signatures.size() > 0)
{
TextSignature textSignature = signatures.get(0);
boolean result = signature.delete("signed-output.pptx",textSignature);
if(result)
{
System.out.print("Signature with Text " + textSignature.getText() + " was deleted from document [signed-output.pptx].");
}
else
{
System.out.print("Signature was not deleted from the document! Signature with Text " + textSignature.getText() + " was not found!");
}
}
} catch (Exception e) {
throw new GroupDocsSignatureException(e.getMessage());
}
