Public API Changes

Presentation Slide Show Setup Settings support

We implemented support for Presentation Slide Show Settings.

Slide Show Settings

These are the relevant classes and properties:

This C# code shows you how to set the Presented by a speaker parameter for a slide show:

using (Presentation pres = new Presentation())
{
    pres.SlideShowSettings.SlideShowType = new PresentedBySpeaker();
    pres.Save("pres.pptx", SaveFormat.Pptx);
}

Browsed by individual parameter:

using (Presentation pres = new Presentation())
{
    BrowsedByIndividual browsedByIndividual = new BrowsedByIndividual {ShowScrollbar = true};
    pres.SlideShowSettings.SlideShowType = browsedByIndividual;
    pres.Save("pres.pptx", SaveFormat.Pptx);
}

Animation Effect.Sound property added

Support for Embedded sound effect has been implemented through the Effect.Sound property.

using (Presentation presentation = new Presentation("demo.pptx"))
{
    ISlide slide = presentation.Slides[0];
    
    // Gets the effects sequence for the slide
    ISequence effectsSequence = slide.Timeline.MainSequence;
       
    foreach (IEffect effect in effectsSequence)
    {
        if (effect.Sound == null)
            continue;
        
        // Extracts the effect sound in byte array
        byte[] audio = effect.Sound.BinaryData;
    }
}
