Understanding Parameters and Methods

  • “John Doe” is the text you want to find.
  • ReplacementOptions defines what replaces the redacted text.

Step 3: Save as PDF

After applying necessary redactions, save the document in PDF format with default settings:

redactor.Save(new PdfSaveOptions());

Key Configuration Options The PdfSaveOptions class allows you to define how your document is saved, including page ranges and image quality.

Troubleshooting Tips

Common issues might include file path errors or unsupported formats. Ensure your document paths are correct, and consult the GroupDocs documentation for format support.
