Regex-Based Text Redaction

Developers using Python can apply regex-based rules to find and cover sensitive text with image masks:

Redact Word Documents Using Regular Expressions

from groupdocs.redaction import Redactor
from groupdocs.redaction.redactions import RegexRedaction, ReplacementOptions
from groupdocs.pydrawing import Color

# Define redaction rules using a regular expression
color = Color.from_argb(255, 220, 20, 60)
repl_opt = ReplacementOptions(color)
reg_red = RegexRedaction("\\d{2}\\s*\\d{2}[^\\d]*\\d{6}", repl_opt)

# Create an instance of the Redactor class
with Redactor("source.docx") as redactor:

    # Mask all matching text with blue square overlays
    result = redactor.apply(reg_red)

    # Save the redacted Word document
    redactor.save()

Remove Metadata

Use the API to erase metadata across multiple file types in just a few steps:

Remove All Metadata from Presentations

from groupdocs.redaction import Redactor
from groupdocs.redaction.redactions import EraseMetadataRedaction, MetadataFilters

# Configure the redaction options
red = EraseMetadataRedaction(MetadataFilters.ALL)

# Provide the path of the presentation to Redactor
with Redactor("source.pptx") as redactor:

    # Erase all metadata from the presentation
    result = redactor.apply(red)

    # Save the cleaned presentation file
    redactor.save()

Image-Area Redaction

Cover a rectangular region of a scanned page or image with a solid color box:

Black Out an Image Area in a PDF

from groupdocs.redaction import Redactor
from groupdocs.redaction.redactions import ImageAreaRedaction, RegionReplacementOptions
from groupdocs.pydrawing import Color, Point, Size

# Define the page area and the color of the box
options = RegionReplacementOptions(Color.from_argb(255, 0, 0, 0), Size(200, 80))
red = ImageAreaRedaction(Point(50, 60), options)

# Provide the document path to Redactor
with Redactor("sample.pdf") as redactor:

    # Black out the selected image region
    result = redactor.apply(red)

    # Save the redacted document
    redactor.save()
