Public API Changes

Animation timing settings: Rewind when done playing - ITiming.Rewind has been added

The ITiming.Rewind attribute has been added to specify whether an effect will rewind after playing.

Example:

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];
    
    // Turns the effect Timing/Rewind on.
    effect.Timing.Rewind = true;
}

Trim Video Settings: IVideoFrame TrimFromEnd and TrimFromStart have been added

IVideoFrame.TrimFromEnd and IVideoFrame.TrimFromStart have been added to manage Trim Video settings.

Example:

using (Presentation pres = new Presentation())
{
    ISlide slide = pres.Slides[0];
    IVideo video = pres.Videos.AddVideo(File.ReadAllBytes("video.mp4"));
    var videoFrame = slide.Shapes.AddVideoFrame(0, 0, 100, 100, video);

    // sets the trimming start time to 1sec
    videoFrame.TrimFromStart = 1000f;

    // sets the triming end time to 2sec
    videoFrame.TrimFromEnd = 2000f;
}

IChartDataPoint.Index property has been added

To allow you determine what parent’s children collection this data point applies to, the IChartDataPoint.Index property has been added.

Example:

using (Presentation presentation = new Presentation("pres.pptx"))
{
    Chart chart = (Chart)presentation.Slides[0].Shapes[0];
    foreach (IChartDataPoint dataPoint in chart.ChartData.Series[0].DataPoints)
    {
        Console.WriteLine($"Point with index {dataPoint.Index} is applied to {dataPoint.Value}");
    }
}
