pip install groupdocs-redaction-net

If you already have the package installed and want to update to the latest version, run:

pip install --upgrade groupdocs-redaction-net

Here are some common use cases to get started.

Example 1: Redact a Phrase in a Document

The following example shows how to redact a phrase in a DOCX file:

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

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)

Example 2: Redact Using Regular Expressions

This example demonstrates how to redact in PDF sensitive patterns like credit card numbers:

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

def run():
    # Specify the redaction options
    color = grd.Color.from_argb(255, 220, 20, 60);
    repl_opt = grr.ReplacementOptions(color)
    reg_red = grr.RegexRedaction(r"\b\d{4}-\d{4}-\d{4}-\d{4}\b", repl_opt)

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

        # Apply the redaction
        result = redactor.apply(reg_red);
        
        # Save the redacted document
        redactor.save()

Example 3: Redact Metadata from a Document

The following example demonstrates how to clean all metadata in a document:

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

def run():
    # Specify the redaction options
    met_red = grr.EraseMetadataRedaction(grr.MetadataFilters.ALL)

    # 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
        redactor.save()
