We were unable to notice any issue while using following code snippet with Aspose.PDF for .NET 20.3:

var objLoadOptions = new Aspose.Pdf.HtmlLoadOptions(dataDir);
// Set Page Margins
objLoadOptions.PageInfo.Margin = new MarginInfo(0, 0, 0, 0);
var doc = new Aspose.Pdf.Document(dataDir + "reviewLetter.html", objLoadOptions);
doc.Save(dataDir + "out20.3.pdf");

out20.3.pdf (128.7 KB)

Would you please try using latest version with shared code snippet and in case you still face any issue, please feel free to let us know.

Thanks for quick response on this. Yes the recommended code worked for file from disk!

Now, what do we need to make it work with loading from stream? We got blank file when we tried.

Thanks.

Would you please share the code snippet with which you are converting HTML to PDF using streams. We will test the scenario in our environment and address it accordingly.

The original problem was that we I did not set HtmlLoadOptions, it is working by given it:

public byte[] GenerateByFile(string fileName)
{
var objLoadOptions = new Aspose.Pdf.HtmlLoadOptions(fileName);
// Set Page Margins
objLoadOptions.PageInfo.Margin = new Aspose.Pdf.MarginInfo(0, 0, 0, 0);
Document pdfDocument = new Document(fileName, objLoadOptions);

        var outStream = new MemoryStream();

        pdfDocument.Save(outStream);
        var bytes = outStream.ToArray();
        return bytes;
    }

However, for our production requirement we have stream/data generated on the fly and in memory. The below code did not work when we tried to load it from stream. We understand the HtmlLoadOptions can load from file only and there must be another way.

public byte[] Generate(string bodyHtml)
{
var stream = new MemoryStream();
var writer = new StreamWriter(stream);
writer.Write(bodyHtml);
writer.Flush();
var objLoadOptions = new Aspose.Pdf.HtmlLoadOptions();
// Set Page Margins
objLoadOptions.PageInfo.Margin = new Aspose.Pdf.MarginInfo(0, 0, 0, 0);
Document pdfDocument = new Document(stream, objLoadOptions);

        var outStream = new MemoryStream();

        pdfDocument.Save(outStream);
        var bytes = outStream.ToArray();
        return bytes;

}
//This will result a blank file.

We tested the scenario using streams as well and were unable to notice the issue. Please check the code snippet that we used:

StringBuilder htmlPage = new StringBuilder();
htmlPage.Append(File.ReadAllText(dataDir + "reviewLetter.html"));
byte[] bytes = Encoding.UTF8.GetBytes(htmlPage.ToString());
var streamHtml = new MemoryStream(bytes);
var objLoadOptions = new Aspose.Pdf.HtmlLoadOptions();
// Set Page Margins
objLoadOptions.PageInfo.Margin = new MarginInfo(0, 0, 0, 0);
var doc = new Aspose.Pdf.Document(streamHtml, objLoadOptions);
doc.Save(dataDir + "out20.3.pdf");

The HtmlLoadOptions takes an argument of the path where those resources are located which are being used in HTML content e.g. images.

Would you kindly share a sample console application which is able to replicate the issue. We will again test the scenario in our environment and address it accordingly.

Thanks for prompt responses and inputs!

The recommended code snippet worked.

Hi,

Please find attached the sample html and pdf generated from it. Why do we see the gray background above the name “Alexander Burgess TEST!” Is it because of the unlicensed version or due to some css/html not supported? Is there a list of non-supported css attributes?Documents.zip (645.5 KB)

Thanks.

@samCDAY

We were able to notice the background issue even with licensed version of the API. The issue seems related to positioning of DIV elements in HTML. However, we need to investigate it further to determine the reasons of issue and rectify them. For the purpose, we have logged an issue as PDFNET-47933 in our issue tracking system. We will look into details of it and keep you posted with the status of its resolution. Please be patient and spare us some time.

We are sorry for the inconvenience.
