I asked a version of this question earlier, but I'm in need of other solutions, so this is a more pointed question.
I'm in need of a server-based solution for converting ppt
files to pdf
files.
This solution can either sit on the current web server as a console command-triggered service, it can be integrated into the C# code of the web all, or it can be it's own server.
It also can't be based off of Libreoffice or Openoffice, as those two have problems converting SmartArt. I'm currently using Libreoffice.
I've tried Powerpoint console commands (/pt
) combined with a PDF print driver (PDFCreator
) but I can't get that to work from C#. The related question for that issue is here
I've tried a .vbs script, but that briefly opens the powerpoint window.
The script, from this answer, is here.
Option Explicit
Sub WriteLine ( strLine )
WScript.Stdout.WriteLine strLine

Another method I tried has this: The problem with this is similar, it opens a (smaller) window briefly.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
namespace ConsoleApplication4
{
class Program
{
static void Main(string[] args)
{
String sourceFilename = args[0];
String destinationFileName = args[1];
if (!File.Exists(sourceFilename))
{
throw new FileNotFoundException(string.Format("The specified file {0} does not exist.", sourceFilename), sourceFilename);
}
try
{
Microsoft.Office.Interop.PowerPoint.Application app = new Microsoft.Office.Interop.PowerPoint.Application();
app.Presentations.Open(sourceFilename,Microsoft.Office.Core.MsoTriState.msoFalse,Microsoft.Office.Core.MsoTriState.msoFalse,Microsoft.Office.Core.MsoTriState.msoFalse).SaveAs(destinationFileName, Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPDF);
app.Quit();
}
catch (Exception e)
{
throw new Exception(string.Format("Unable to convert {0} to {1}", sourceFilename, destinationFileName), e);
}
}
}
}
