Hello, I am trying to add a watermark to the blank section of my document, not the entire page. So I need to generate the .pdf first to determine if I have white space first. This is my code:

HtmlToPdfResult convertResult = EO.Pdf.HtmlToPdf.ConvertHtml(printOutHtml, doc);

// add watermark if enough blank space on last page
if (convertResult.LastPosition > 2)
{
PdfPage page = doc.Pages[convertResult.LastPageIndex];

HtmlToPdf.ConvertHtml("DO NOT WRITE IN THIS SPACE!", page);
}

This puts "DO NOT WRITE IN THIS SPACE!" at the top of the page. What I want is the diagonal traditional watermark in my blank space. I found an example on your website but it renders it before the content is created. I do like the layout of the watermark though. Is there some way to salvage this code without having to create an event? I guess I'm just trying to add the textLayer object back onto my existing .pdf page.

private void BeforeRenderPage(object sender, AcmPageEventArgs e)
{
//Create a new text layer
EO.Pdf.Contents.PdfTextLayer textLayer = new EO.Pdf.Contents.PdfTextLayer();

//Use a big font, light text color and also
//rotate the text 45 degrees
textLayer.Font = new EO.Pdf.Drawing.PdfFont("Arial", 50);
textLayer.NonStrokingColor = Color.LightGray;
textLayer.GfxMatrix.Rotate(45);

//Create the text object
EO.Pdf.Contents.PdfTextContent textContent = new EO.Pdf.Contents.PdfTextContent("CONFIDENTIAL");
textContent.PositionMode = EO.Pdf.Contents.PdfTextPositionMode.Offset;
textContent.Offset = new EO.Pdf.Drawing.PdfPoint(350, 150);

//Add the text object into the text layer object
textLayer.Contents.Add(textContent);

//Add the text layer into the page
e.Page.Contents.Add(textLayer);
}
