Overview of Deleting Text Signatures

Deleting text signatures involves identifying them using their unique SignatureId and then removing them from the document. This feature is essential for updating or revoking electronic signatures as needed.

Step 1: Import Required Classes

First, ensure you have imported all necessary classes:

import com.groupdocs.signature.Signature;
import com.groupdocs.signature.domain.DeleteResult;
import com.groupdocs.signature.domain.signatures.BaseSignature;
import java.io.File;
import java.util.ArrayList;
import java.util.List;

Step 2: Set Up File Paths

Define the input and output file paths. Replace placeholders with your actual document paths.

String filePath = "YOUR_DOCUMENT_DIRECTORY";
File inputFile = new File(filePath);
String fileName = inputFile.getName();
String outputFilePath = new File("YOUR_OUTPUT_DIRECTORY\
