Aspose.PDF Product Family

Hi,
I am try to generate a pdf from html string or a html file but the CSS is not rendering consistent through out the PDF. My Html has table and the border for table are dark for some rows and column while lite for others. I have used two approach for this and i am getting same result from both approach.

My First Approach:

StringBuilder html = new StringBuilder();

string PdfHtmlTemplateHead = @"";
html.Append(PdfHtmlTemplateHead);
html.Append(File.ReadAllText(“E:\CSS\PdfCOOPPremManulifeCss.css”));
string PdfHtmlTemplateBody = @" HTML TABLE HERE ";
html.Append(PdfHtmlTemplateBody);

  		HtmlLoadOptions objLoadOptions = new HtmlLoadOptions();
            objLoadOptions.PageInfo.Margin.Bottom = 10;
            objLoadOptions.PageInfo.Margin.Top = 30;
            objLoadOptions.PageInfo.Margin.Left = 10;
            objLoadOptions.PageInfo.Margin.Right = 10;
            objLoadOptions.PageInfo.Width = Aspose.Pdf.PageSize.A4.Width;

            Document doc = new Document(new MemoryStream(Encoding.UTF8.GetBytes(html.ToString())), objLoadOptions);
            string FileName = "Sample_" + DateTime.Now.ToString("dd-MM-yyyy") + ".pdf";
            //Save PDF file on local hard drive or database or as you wish          
            doc.Save(@"E:\Aspose\" + FileName);

My Second approach:

String basePath = @“E:\CSS2”;
HtmlLoadOptions objLoadOptions = new HtmlLoadOptions(basePath);
objLoadOptions.PageInfo.Margin.Bottom = 10;
objLoadOptions.PageInfo.Margin.Top = 30;
objLoadOptions.PageInfo.Margin.Left = 10;
objLoadOptions.PageInfo.Margin.Right = 10;
objLoadOptions.PageInfo.Width = Aspose.Pdf.PageSize.A4.Width;

            //Load HTML string into MemoryStream using Aspose document class
            Document doc = new Document(@"E:\CSS2\testqc.html", objLoadOptions);
            string FileName = "Sample_" + DateTime.Now.ToString("dd-MM-yyyy") + ".pdf";
            //Save PDF file on local hard drive or database or as you wish          
            doc.Save(@"E:\Aspose\" + FileName);

I am using this piece of CSS to apply border in my table:

table, tr{
border: 1px solid black;
border-collapse: collapse;
}

But the output is not consistent. I am attaching screenshot of the output.aspose_output.PNG (62.1 KB)

So as per my understanding there is nothing to do from your end in this issue. Right?
Also can you please share the version of Adobe in which the scaling is perfect, so that we can use that version.

Thanks
