Delete Image signatures from documents Leave feedback

GroupDocs.Signature provides ImageSignature class to manipulate image signatures and delete them from the documents over Delete method.
Please be aware that Delete method modifies the same document that was passed to constructor of Signature class.

Here are the steps to delete Image signature from the document with GroupDocs.Signature:

• Create new instance of Signature class and pass source document path as a constructor parameter;
• Instantiate ImageSearchOptions object with desired properties;
• Call Search method to obtain list of ImageSignature;
• Select from list ImageSignature 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 Image signature that was found using Search method.

import groupdocs.signature as signature
from groupdocs.signature.options import ImageSearchOptions

# Initialize signature
with signature.Signature("signed.pptx") as sign:
    # Create search options
    options = ImageSearchOptions()
    
    # Search for image signatures in the document
    signatures = sign.search(options)
    
    if len(signatures) > 0:
        image_signature = signatures[3]
        result = sign.delete(image_signature)
        
        if result:
            print(
                f"Image signature at location {image_signature.left}x{image_signature.top} "
                f"and size {image_signature.size} was deleted from document ['{fileName}']."
            )
        else:
            print(
                f"Signature was not deleted from the document! "
                f"Signature at location {image_signature.left}x{image_signature.top} "
                f"and size {image_signature.size} was not found!"
            )
