I just installed Slide and PDF .net trial. I compiled and tested the console app "ppt2pdf" and tested it with a simple presentation. The app crash at the line :
System.Drawing.Bitmap bitmap =(System.Drawing.Bitmap)slide.GetThumbnail(1.0,1.0);
I decided to test the webform ppt2pdf and I got thi message :
I'm sorry, PPT2PDF demo couldn't open your presentation
The PPT document was created with PPT 2007 but saved to a 2003 file. The ppt contains images, 3D objects, animation. I simple prensentation of 14 slides.
Is there some restrictions on the slide content.
