Aspose.PDF Product Family

Hi,

I am trying to download an HTML file from a URL , this cannot be saved onto disc and therefore after download needs to be converted into PDF.

This is for our customer who is already using Aspose for word and PDF but this time we need to extend this functionality for HTML files.

Please can you tell exactly how we can achieve this.

Regards

Dear Tilal,

I have followed the sample but unfortunately the converted document is un readable. I have attached the Sample HTML document along the output pdf pages. Please help.

Hi Umer,


Thanks for your feed back. I am afraid while testing the scenario with Aspose.Pdf for .NET 9.1.0, we are unable to replicate the issue. Please download and try latest version of Aspose.Pdf for .NET, it will fix the issue.

Best Regards,

Thanks Tilal. that solved the problem but we will also have to update the Aspose.PDF dll on customer environment and hope it doesn't break any thing.

One more question, do you have any example for MHT to PDF conversion using same scenario? i.e. mht files is stored as a URL link and we need to download this, convert to PDF without storing on disc.

Thanks

Hi Tilal,


Our customer has reported one more problem regarding HTML reference file to PDF conversion. The referee comment includes some monetary figures with currency sign such as pound E.g. "£ 2.5 Million" whereas the converted PDF file is not showing £ sign and a box instead. Please see the attached HTML reference and converted PDF file screenshot.

Following is the code lines for HTML document to PDF conversion.


// Create a request for the URL.
WebRequest request = WebRequest.Create(documentURI);
// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Get the response.
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

// Get the stream containing content returned by the server.
Stream dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
reader.Close();
dataStream.Close();
response.Close();

MemoryStream stream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(responseFromServer));
HtmlLoadOptions options = new HtmlLoadOptions(documentURI);

// use the new conversion engine
options.UseNewConversionEngine = true;

// load HTML file
Aspose.Pdf.Document pdfDoc = new Aspose.Pdf.Document(stream,options);
crmAccess.pdfDocuments.Add(pdfDoc);

Please can you help to identify the issue?

Thanks

Hi Umer,

Thanks for your inquiry. I have tested the scenario with Aspose.Pdf for .NET 9.2.1 and unable to replicate the issue. Please download and try the latest version of Aspose.Pdf for .NET and share the results. Hopefully, it will help you to resolve the issue.

HtmlLoadOptions htmloptions = new HtmlLoadOptions();

// use the new conversion engine
htmloptions.UseNewConversionEngine = true;
htmloptions.PageInfo.Width = 900;
htmloptions.PageInfo.Height = 590;

// load HTML file
Document doc = new Document(myDir + "ReferenceSampleCurrency.html", htmloptions);
doc.Save(myDir + "HTMLtoPDFDOM.pdf");

Please feel free to contact us for any further assistance.

Hi Tilal,

Unfortunately the problem is still not resolved. I have downloaded the latest version of Aspose.PDF(9.2.1) and used this in code but this time pound sign is even converted into more strange value.

Please see the attachment. Please can you try downloading HTML file from URI and reading into memory stream and convert into PDF, essentially same way I did and this way you might be able to reproduce the issue!

Thanks
