I'm trying to create JPG thumbnails from my PDFs for use on a website.

When I use the RenderDocumentToFile method I get about a 50% ratio of blank JPGs - a valid file, but it's completely blank. I did read about RenderToStream but that's only valid in Delphi. I need to get this working in VBA if possible please.

Cheers

public partial class Test : System.Web.UI.Page

    protected void Page_Load(object sender, EventArgs e)
    {
        SEDTech.iSED.QuickPDF iQPDF = new QuickPDF();
        iQPDF.UnlockKey("key");//Please enter your key!
        string PgcFilePath = @Request.PhysicalApplicationPath + "iSEDQuickPDF 5.11 Reference Guide.pdf";
        int result = iQPDF.LoadFromFile(PgcFilePath);
        int pages = iQPDF.PageCount();
        if (result == 1)
        {
            if (iQPDF.Encrypted() == 0)
            {
                iQPDF.RenderDocumentToFile(72, 1, pages, 1, @Request.PhysicalApplicationPath + "Images\\Image" + pages + ".jpg");
            }
            else
            {
                iQPDF.Unencrypt();
                iQPDF.RenderDocumentToFile(72, 1, pages, 1, @Request.PhysicalApplicationPath + "Images\\Image" + pages + ".jpg");
            }
