I'm trying to overlay a banner in the header region of each page.

This is the code I'm currently using and it produces the result shown in the image. Please assist me in being able to better position the banner. I couldn't insert the screenshot. I can send an email if having a visual helps.

Code: C#

Copy

MemoryStream stream = new(fileBytes);
            PdfDocument document = new PdfDocument(stream);
            PdfPage page = document.Pages[0];

            HtmlToPdfOptions options = new()
            {
                HeaderHtmls = new string[] { $@"&lt;div id=""aur-watermark"" style=""border: 3px solid black; padding: 4px; width: max-content; font-size: 10px""&gt;
                                        &lt;strong&gt;Aurelia Dormamu Information&lt;/strong&gt;&lt;br&gt;
                                        Controlled by: &lt;span id=""aur-controller""&gt;XXXXXX&lt;/span&gt;
                                        &lt;/div&gt;" },
                //HeaderHtmlPosition = 20.5f
            };

            EO.Pdf.HtmlToPdf.Options.OutputArea = new RectangleF(406f, 785f, 8.5f, 11f);

            var result = EO.Pdf.HtmlToPdf.ConvertHtml($@"", page, options);

Hi,

The header position is determined as follow:

Left: OutputArea.Left. In your case it would 406f;
Top: HeaderHtmlPosition;

As a test, you can set both as 0 and then the header will start immediately from the top left corner of the page. You can then adjust your HeaderHtml to position the actual content. For example, if you want to move the header html to the right, add a padding left to your HTML.

Also why do you have such large Left/Top value for your OutputArea?

Thanks!
