Pre-rasterize

In some cases, you might need to pre-rasterize the document before opening it and applying redactions.

For instance, you might need to use an ImageAreaRedaction for a whole page of a document with search-able text and images. In order to do that, you will need to pass the Boolean flag to the LoadOptions class constructor.

The following example demonstrates how to pre-rasterize a Microsoft Word document:

Python

import groupdocs.redaction as gr
import groupdocs.redaction.redactions as grr
import groupdocs.pydrawing as grd

def run():
    
    # Specify the redaction options
    repl_opt = grr.ReplacementOptions("[personal]")
    ex_red = grr.ExactPhraseRedaction("John Doe", repl_opt)

    # Load the document to be redacted
    with gr.Redactor("source.docx") as redactor:

        # Apply the redaction
        result = redactor.apply(ex_red)

        if (result.status != gr.RedactionStatus.FAILED):
            # By default, the redacted document is saved in PDF format
            result_path = redactor.save()
        else:
            print(f"Redaction failed!")
