Get Font List of Unknown Fonts

This PPT API release offers the ability to fetch the list of all unknown fonts. This lets you know the fonts which need to be substituted or replaced for the correct rendering of presentation slides.

using (Presentation pres = new Presentation("pres.pptx"))
{
    foreach (var fontSubstitution in pres.FontsManager.GetSubstitutions())
    {
        Console.WriteLine("{0} -> {1}", fontSubstitution.OriginalFontName, fontSubstitution.SubstitutedFontName);
    }
} 

Configure Slide Effect Repetition Behavior

Couple of new properties have been added to the Timing class. These properties let you configure if the slide effect will be repeated till the next click or the effect should be repeated till the end of slide.

The following C# sample code demonstrates:

1. How to fetch the effects sequence of the desired slide
2. Get the desired effect that you want to repeat
3. Set the slide effect repeat timing till the end of slide via API

using (Presentation presentation = new Presentation("demo.pptx"))
{
    // Gets the effects sequence for the first slide
    ISequence effectsSequence = presentation.Slides[0].Timeline.MainSequence;

    // Gets the first effect of the main sequence.
    IEffect effect = effectsSequence[0];

    // Changes the effect Timing/Repeat to "Until End of Slide"
    effect.Timing.RepeatUntilEndSlide = true;
}
