Dear Support Team,
We use eo.pdf to generate PDF from HTML and SVG, The result PDF file work perfect if we open it on Mac. 
but on windows pc , some time we saw strange error message "A drawing error occurred." even the file is worked on Mac.
we use following code to convert PDF
            using (StreamReader sr = new StreamReader(@"donuts.html"))
            {
                String line = sr.ReadToEnd();
                HtmlToPdf.ConvertHtml(line, @"donuts.pdf");
            }
and sample file is include in this link
