Thanks

Thank you for contacting support.

You can redact any area of a page, as explained in Redact certain page region with RedactionAnnotation.

We hope this will be helpful. Please feel free to contact us if you need any further assistance.

Redaction will not work for me.
Redaction removes all the text in a rectangle.
But I have set of string that would be searched from the Rectangular area. Thereafter, remove that text OR replace with some other string.

You can search and replace text by specifying Rectangular coordinates in below code snippet and replace or remove that word as per your requirements.

// load PDF file
Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document((dataDir + "Test.pdf"));
foreach (Aspose.Pdf.Page page in pdfDocument.Pages)
{
    // instantiate TextFragment Absorber object
    Aspose.Pdf.Text.TextFragmentAbsorber TextFragmentAbsorberAddress = new Aspose.Pdf.Text.TextFragmentAbsorber("SEARCH");
    // search text within page bound
    TextFragmentAbsorberAddress.TextSearchOptions.LimitToPageBounds = true;
    // specify the page region for TextSearch Options
    TextFragmentAbsorberAddress.TextSearchOptions.Rectangle = new Aspose.Pdf.Rectangle(0, 0, page.PageInfo.Width, page.PageInfo.Height);
    // search text from first page of PDF file
    page.Accept(TextFragmentAbsorberAddress);
    // iterate through individual TextFragment
    foreach (Aspose.Pdf.Text.TextFragment tf in TextFragmentAbsorberAddress.TextFragments)
    {
        // Replace text
        tf.Text = "REPLACE";

        // Remove text
        // tf.Text = "";
    }
}
// save updated PDF file after text replace
pdfDocument.Save(dataDir + "TextReplaced_18.10.pdf");
