Using redaction filters Leave feedback

GroupDocs.Redaction lets you set a page-based scope for a redaction, of two kinds:

• Page range — a number of pages at a given offset from the beginning or the end of the document;
• Page area — a top-left-based rectangle applied on each page.

All filters inherit from RedactionFilter and are passed as an array to the filters property of ReplacementOptions. Combine both kinds in one set to scope a redaction to an area on specific pages.

Redaction filters apply to PDF documents. Support for additional formats is planned for future releases of GroupDocs.Redaction.

• Use PDF Redaction Filters — a runnable example that combines a page-range filter and a page-area filter to scope a redaction in a PDF.
