Use advanced rasterization options Leave feedback
On this page
In order to use the advanced rasterization options you have to pass one of the options to Save method. In this case the document will be rasterized to PDF, but the scan-like effects will be applied to its pages.
The following example demonstrates how to apply the AdvancedRasterizationOptions with default settings.
from groupdocs.redaction import Redactor
from groupdocs.redaction.options import SaveOptions, AdvancedRasterizationOptions
from groupdocs.redaction.redactions import ExactPhraseRedaction, ReplacementOptions
def use_advanced_rasterization_options():
# Specify the redaction options
repl_opt = ReplacementOptions("[personal]")
ex_red = ExactPhraseRedaction("John Doe", repl_opt)
# Load the document to be redacted
with Redactor("./sample.docx") as redactor:
# Apply the redaction
redactor.apply(ex_red)
# Save the document with advanced options (convert pages into images, and save PDF with scan-like pages)
so = SaveOptions()
so.rasterization.enabled = True
so.redacted_file_suffix = "_scan"
so.rasterization.add_advanced_option(AdvancedRasterizationOptions.BORDER)
so.rasterization.add_advanced_option(AdvancedRasterizationOptions.NOISE)
so.rasterization.add_advanced_option(AdvancedRasterizationOptions.GRAYSCALE)
so.rasterization.add_advanced_option(AdvancedRasterizationOptions.TILT)
result_path = redactor.save(so)
print(f"Document redacted successfully.\nCheck output in {result_path}")

The following example demonstrates how to apply the grayscale advanced rasterization option.
from groupdocs.redaction import Redactor
from groupdocs.redaction.options import SaveOptions, AdvancedRasterizationOptions
def use_grayscale_rasterization_option():
# Load the document to be redacted
with Redactor("./sample.docx") as redactor:
# Save the document with the custom grayscale effect
so = SaveOptions()
so.rasterization.enabled = True
so.redacted_file_suffix = "_scan"
so.rasterization.add_advanced_option(AdvancedRasterizationOptions.GRAYSCALE)
result_path = redactor.save(so)
print(f"Document redacted successfully.\nCheck output in {result_path}")
