Hi! I have generated PDF from HTML using PDFSharp, all images are from stream

Code:
   
        var pngBinaryDataLogoLeft = File.ReadAllBytes(folderPath + "logo.png");
        var ImgDataURILogoLeft = @"data:image/png;base64," + Convert.ToBase64String(pngBinaryDataLogoLeft);
        html = html.Replace("[logoLeft]", ImgDataURILogoLeft);

        var pngBinaryDataBGImg = File.ReadAllBytes(folderPath + "background.png");
        var ImgDataURIBGImg = @"data:image/png;base64," + Convert.ToBase64String(pngBinaryDataBGImg);
        html = html.Replace("[BGImg]", ImgDataURIBGImg);

        var config = new PdfGenerateConfig();
        config.PageOrientation = PageOrientation.Landscape;
        config.PageSize = PdfSharpPageSize.A4;

        string cssStr = File.ReadAllText(folderPath + "1.css");
        CssData css = PdfGenerator.ParseStyleSheet(cssStr);

        PdfSharp.Pdf.PdfDocument pdf = PdfGenerator.GeneratePdf(html, config, css);

        MemoryStream stream = new MemoryStream();
        pdf.Save(stream, false);
        byte[] bytes = stream.ToArray();

        File.WriteAllBytes(folderPath + "document.pdf", bytes);


In my HTML the img get replaced by stream are working fine

Code:
<img class="logo-left" src="[logoLeft]" />



But the background image doesn't work:

Code:
<body style="background: url('[BGImg]')">



I don't have the image from a URL as it's from database (saved as stream)

I also tried to add the background image first to a new PDF page like below:

Code:
XGraphics gfx = XGraphics.FromPdfPage(pdf.Pages[0]);
XImage image = XImage.FromFile(bgImgPath);
gfx.DrawImage(image, x, y, width, height);


But then I couldn't add the content from HTML to the same page

If someone could please help thanks!!

You do not use PDFsharp, you use HTML Renderer. Not our product, but maybe someone here can help.
