Here are the steps to delete Barcode signature from the document with GroupDocs.Signature:
- Create new instance of Signature class and pass source document path as a constructor parameter;
- Instantiate BarcodeSearchOptions object with desired properties;
- Call Search method to obtain list of BarcodeSignature;
- Select from list BarcodeSignature 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 Barcode signature that was found using Search method.
using (Signature signature = new Signature("signed.docx"))
{
BarcodeSearchOptions options = new BarcodeSearchOptions();
// search for Barcode signatures in document
List<BarcodeSignature> signatures = signature.Search<BarcodeSignature>(options);
if (signatures.Count > 0)
{
BarcodeSignature barcodeSignature = signatures[0];
bool result = signature.Delete(barcodeSignature);
if (result)
{
Console.WriteLine(
$"Signature with Barcode '{barcodeSignature.Text}' and " +
$"encode type '{barcodeSignature.EncodeType.TypeName}' " +
$"was deleted from document ['{fileName}']."
);
}
else
{
Console.WriteLine(
$"Signature was not deleted from the document! " +
$"Signature with Barcode '{barcodeSignature.Text}' and " +
$"encode type '{barcodeSignature.EncodeType.TypeName}' " +
$"was not found!"
