RTF Conversion

Hi GroupDocs,

We’re running into an issue that seems to occur when converting .RTF documents with tiny left/right margins to PDF. Part of the document gets cut off when you try to view it in Adobe Reader after conversion. The same does not happen if you convert the .RTF to .PDF via Microsoft Word.

Here is our code:

public async Task<Stream> RenderDocumentAsPdfAsync(Stream document, string documentName)

Guard.ArgumentNotNullOrEmpty(documentName, “documentName”);

var config = GetViewerConfig();
var imgHandler = new ViewerImageHandler(config);
var pdfOptions = GetPdfOptions();
var fileContainer = new FileContainer();

    var memoryStream = new MemoryStream();
    await document.CopyToAsync(memoryStream); 
    fileContainer = await Task.Run(() => imgHandler.GetPdfFile(memoryStream, pdfOptions));

catch (Exception ex)
    ApplicationLogger.LogError(string.Format("Conversion of document {0} to PDF failed.  Exception: {1}", documentName, ex.ToString()), 
        MethodBase.GetCurrentMethod(), exception: ex);
    return null;
return fileContainer.Stream;

private static ViewerConfig GetViewerConfig()


var config = new ViewerConfig()
    UseCache = false,
return config;
