Redaction issue when too close to bottom of page

Aspose.PDF Product Family

Hi,

The following code with the attached single page PDF fails if the Lower Left Y is anything less than 16 but it works with 16:

        var pageDoc = new Aspose.Pdf.Document(@"C:\temp\redaction\887649.pdf");
        pageDoc.PageInfo.Margin.Bottom = 20;
        pageDoc.PageInfo.Margin.Top = 0;
        pageDoc.PageInfo.Margin.Left = 0;
        pageDoc.PageInfo.Margin.Right = 0;
        pageDoc.PageInfo.Height = pageDoc.Pages[1].TrimBox.Height;
        pageDoc.PageInfo.Width = pageDoc.Pages[1].TrimBox.Width;

        // Change lly from 16 to 15 and the redaction fails with "Index was outside the bounds of the array" exception
        Rectangle redactionArea = new Rectangle(543,15,611,33);

        var redaction = new RedactionAnnotation(pageDoc.Pages[1], redactionArea);
        redaction.FillColor = Color.White;
        redaction.BorderColor = Color.White;
        redaction.Color = Color.White;

        pageDoc.Pages[1].Annotations.Add(redaction);
        // This line will fail if lly is 15 or less
        redaction.Redact();

        pageDoc.Save(@"C:\temp\redaction\887649_redacted.pdf");

I have a similar example on a landscape page but that works when the redaction is in the bottom right corner so very confusing!

Using 19.7 of Aspose.PDF but also just tested with 19.8, same issue
