To load an Office document for conversion from a stream, use the LoadFromStream method from the GdPictureDocumentConverter class.

LoadFromStream accepts:

  • Stream — The input stream containing the document data.
  • DocumentFormat (optional) — A member of the DocumentFormat enumeration.

For example, DocumentFormat can be:

  • Word — DocumentFormat.DocumentFormatDOCX
  • Excel — DocumentFormat.DocumentFormatXLSX
  • PowerPoint — DocumentFormat.DocumentFormatPPTX

LoadFromStream returns a GdPictureStatus, which should always be checked before conversion.

To load and convert an Office document from a stream (example: Word to PDF), use the following code:

using GdPicture14;
using System;
using System.IO;


// Create a stream object from a Word file.
using Stream streamFile = new FileStream(@"C:\temp\source.docx", FileMode.Open, FileAccess.Read);
using GdPictureDocumentConverter converter = new GdPictureDocumentConverter();


GdPictureStatus status = converter.LoadFromStream(streamFile, DocumentFormat.DocumentFormatDOCX);
if (status != GdPictureStatus.OK)
{
    Console.WriteLine($"LoadFromStream failed: {status}");
    return;
}


status = converter.SaveAsPDF(@"C:\temp\output.pdf");
if (status != GdPictureStatus.OK)
{
    Console.WriteLine($"SaveAsPDF failed: {status}");
}
