Answer 1

Hello,

for PowerPoint 2010:

in GUI: File -> Save As... -> Choose File-Type (e.g. jpg). You will be prompted if you want to save the current or all slides

in Code: If you have the 'Slide' Instance (e.g. Application.ActivePresentation.Slides[1]), you can use the 'Export' Method:

slide.Export("C:\\temp\\slide.jpg", "JPG");

OK?

Hey Günter!

 

Thanks for your reply (Grüße von einem ehemaligen WD-Mitarbeiter)! I already found the solution.

For others: You need the following Refernces for the project:

Microsoft.Office.Core and Microsoft.Office.Interop.PowerPoint

        ApplicationClass appPowerpoint = new ApplicationClass();
        Presentation pres = appPowerpoint.Presentations.Open(ppFilePath, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);
        foreach (Slide s in pres.Slides)
        {
          string id = Guid.NewGuid().ToString();
          s.Export(Path.Combine(destinationPath, id.ToString() + ".jpg"), "jpg", imageWidth, imageHeight);

        }

That easy!
