Background images not showing in pdf (sometimes)

[danm]

I have an hrtml page that I am converting to a pdf like

Code: Select all

Spire.Pdf.PdfDocument pp = new Spire.Pdf.PdfDocument();
        Spire.Pdf.PdfPageSettings pst = new Spire.Pdf.PdfPageSettings();
        PdfHtmlLayoutFormat format = new PdfHtmlLayoutFormat();

        format.FitToPage = Clip.Both;
        format.Layout = PdfLayoutType.OnePage;

        pst.Size = Spire.Pdf.PdfPageSize.Letter;
        pst.Orientation = Spire.Pdf.PdfPageOrientation.Portrait;
        pst.SetMargins(0);

        string testUrl = theDestUrl;

        Thread thread = new Thread(() =>
        {
            pp.LoadFromHTML(testUrl, true, true, false, pst, format);
        });

        thread.SetApartmentState(ApartmentState.STA);
       
            thread.Start();
            thread.Join();
       
        string path = pathToSaveFile;
        pp.SaveToFile(path, Spire.Pdf.FileFormat.PDF);


The page has some background images that are set and configured in css. Sometimes the background images appear in the generated pdf, sometimes they don't, and sometimes some of the background images appear while others do not.

I am using the Spire.Pdf dll version 3.2.31.5040.

If I bring the html page up in IE it appears fine with all the background images.

Dear damn,

Thanks for your inquiry.

After some investigation, I guess the problem is the page don't load at all sometimes, please set

Code: Select all

format.IsWaiting = true;


to wait the page load completely.
