Saving as PDF - no images when deployed to IIS

Aspose.Words Product Family
1

We are currently using Aspose.Words for .NET version 18.9.0. We use embedded Word Templates and use replace to replace values on the templates. We then save it as PDF using:

var physicalFile = Path.Combine(_configuration[“LettersFolder”], Guid.NewGuid().ToString());
doc.Save(physicalFile, SaveFormat.Pdf);

Everything is working fine when debugging using Visual Studio 2017, but when deployed to IIS, the saved PDF loses the Word images.

We are using .NET Core 2.1. Target runtime when publishing is Win-x64

Attached template and sample output.

Additional Information:

I installed IIS on my desktop and it is working fine as well. Images are not showing when deployed on IIS of server which is Windows Server 2016 Standard with IIS 10.

Also created a .NET Core Console App using .NET Core version 2.1.4 - images appear fine when console app was run on my desktop. But running it on server generates PDF with no images as well.

Could you please execute the following code at your server and share the list of warnings that you will receive? Thanks for your cooperation.

Document document = new Document(MyDir + "input.docx");
document.WarningCallback = new DocumentWarnings();
document.Save(MyDir + "18.10.pdf");

public class DocumentWarnings : IWarningCallback
{
    public void Warning(WarningInfo info)
    {
        Console.WriteLine(info.WarningType + " :: " + info.Description.ToString());
    }
}

Hi @tahir.manzoor

Sorry for the late response but we have resolved the issue by installing Visual C++ redistributable.

We did not know that this is needed even though we are using .NET Core. Thanks.
