Apply Exact Phrase Redaction

This code sample demonstrates how to apply exact phrase redaction to a document by replacing a specific phrase with a custom string or a colored rectangle. The example shows how to use GroupDocs.Redaction for Python via .NET to redact sensitive information by identifying and replacing exact phrases.

import groupdocs.redaction as gr
import groupdocs.redaction.options as gro
import groupdocs.redaction.redactions as grr

# Learn how to use GroupDocs.Redaction for Python via .NET to apply exact phrase redaction to documents, replacing sensitive text with custom content or a colored block.

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)
        
        # Save the redacted document
        so = gro.SaveOptions()
        so.add_suffix = True
        so.rasterize_to_pdf = False
        result_path = redactor.save(so)

Redact Metadata in a Document

This example shows how to remove sensitive metadata from a document using regular expressions. It targets specific fields, such as the author’s name, for redaction. The sample uses Python syntax to demonstrate metadata redaction with GroupDocs.Redaction for Python via .NET.

import groupdocs.redaction as gr
import groupdocs.redaction.options as gro
import groupdocs.redaction.redactions as grr

#Redact metadata in a document using GroupDocs.Redaction for Python via .NET. Remove or replace sensitive metadata fields like author names.

def run():

    # Specify the redaction options
    met_red = grr.MetadataSearchRedaction("Company Ltd.", "--company--")

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

        # Apply the redaction
        result = redactor.apply(met_red)
        
        # Save the redacted document
        so = gro.SaveOptions()
        so.add_suffix = True
        so.rasterize_to_pdf = False
        result_path = redactor.save(so)

Redact Specific Areas in Document Images

This example demonstrates how to redact a specific area of an image embedded in a document by overlaying a colored rectangle, using GroupDocs.Redaction for Python via .NET.

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

# Use GroupDocs.Redaction for Python via .NET to redact specific areas of images embedded in documents by overlaying colored rectangles on sensitive regions.

def run():
    
    # Define the position on image
    sample_point = grd.Point(516, 311)
    # Define the size of the area which need to be redacted
    sample_size = grd.Size(170, 35)
    # Define color of redaction
    color = grd.Color.from_argb(255, 220, 20, 60)

    # Specify the redaction options
    repl_opt = grr.RegionReplacementOptions(color, sample_size)
    img_red = grr.ImageAreaRedaction(sample_point, repl_opt)

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

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

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