GroupDocs.Signature simplifies the task for .NET developers to remove electronic signatures in PPTX files by implementing a few straightforward steps.
// Pass the document containing signatures to the Signature instance
using (Signature signature = new Signature("input.pptx"))
{
// Retrieve the digital signatures present within the document
DigitalSearchOptions options = new DigitalSearchOptions();
List<DigitalSignature> signatures = signature.Search<DigitalSignature>(options);
// Remove the first identified digital signature
if(signatures.Count > 0)
{
DigitalSignature digitalSignature = signatures[0];
bool result = signature.Delete(digitalSignature);
// Remove the first identified digital signature
if(result)
{
Console.WriteLine($"Digital signature in PPTX was deleted successfully");
}
}
}
