Public API Changes

IAudioFrame.PlayAcrossSlides and IAudioFrame.RewindAudio properties have been added

New properties PlayAcrossSlides and RewindAudio have been added to the IAudioFrame interface and AudioFrame class.

The PlayAcrossSlides property allows determining whether audio is playing across the slides.

Property declaration:

/// <summary>
/// Determines whether audio is playing across the slides.
/// Read/write <see cref="bool"/>.
/// </summary>
bool PlayAcrossSlides { get; set; }

The RewindAudio property allows determining whether audio is automatically rewinded to start after playing.

Property declaration:

/// <summary>
/// Determines whether audio is automatically rewinded to start after playing.
/// Read/write <see cref="bool"/>.
/// </summary>
bool RewindAudio { get; set; }

The code snippet below demonstrates adding the AudioFrame and changing its properties:

using (Presentation pres = new Presentation())
{
    ISlide slide = pres.Slides[0];

    // Add Audio Frame
    IAudioFrame audioFrame = slide.Shapes.AddAudioFrameLinked(50, 50, 100, 100, "sampleaudio.wav");

    // Set Audio to play across the slides
    audioFrame.PlayAcrossSlides = true;

    // Set Audio to automatically rewind to start after playing
    audioFrame.RewindAudio = true;

    pres.Save("AudioFrame_out.pptx", SaveFormat.Pptx);
}

InClickSequence value has been added to AudioPlayModePreset enumeration

InClickSequence value has been added to AudioPlayModePreset enumeration. It represents In Click Sequence audio start play mode.

The code snippet below demonstrates adding the AudioFrame and changing its play mode:

using (Presentation pres = new Presentation())
{
    ISlide slide = pres.Slides[0];

    // Add Audio Frame
    IAudioFrame audioFrame = slide.Shapes.AddAudioFrameLinked(50, 50, 100, 100, "sampleaudio.wav");

    // Set audio play mode to In Click Sequence
    audioFrame.PlayMode = AudioPlayModePreset.InClickSequence;

    pres.Save("AudioFrame_out.pptx", SaveFormat.Pptx);
}

InClickSequence value has been added to VideoPlayModePreset enumeration

InClickSequence value has been added to VideoPlayModePreset enumeration. It represents In Click Sequence video start play mode.

The code snippet below demonstrates adding the VideoFrame and changing its play mode:

using (Presentation pres = new Presentation())
{
    ISlide slide = pres.Slides[0];

    // Add Video Frame
    IVideoFrame videoFrame = slide.Shapes.AddVideoFrame(50, 50, 200, 150, "samplevideo.wmv");

    // Set video play mode to In Click Sequence
    videoFrame.PlayMode = VideoPlayModePreset.InClickSequence;

    pres.Save("VideoFrame_out.pptx", SaveFormat.Pptx);
}

IOleObjectFrame.SetEmbeddedData method and IOleObjectFrame.EmbeddedData property have been added

A new method SetEmbeddedData and a new property EmbeddedData have been added to the IOleObjectFrame interface and OleObjectFrame class.

These method and property allow to get, set and change an embedded data and its type of OLE object.

Property declaration:

/// <summary>
/// Gets information about OLE embedded data.
/// Read only <see cref="IOleEmbeddedDataInfo"/>.
/// </summary>
IOleEmbeddedDataInfo EmbeddedData { get; }

Method declaration:

/// <summary>
/// Sets information about OLE embedded data.
/// </summary>
/// <remarks>
/// This method changes the properties of the object to reflect the new data and 
/// sets the IsObjectLink flag to false, indicating that the OLE object is embedded.
/// </remarks>
/// <param name="embeddedData">Embedded data <see cref="IOleEmbeddedDataInfo"/></param>
/// <exception cref="ArgumentNullException">When embeddedData parameter is null.</exception>
void SetEmbeddedData(IOleEmbeddedDataInfo embeddedData);

The code snippet below demonstrates getting and changing OLE embedded data in existing OLE object:

using (Presentation pres = new Presentation("pres.pptx"))
{
    OleObjectFrame oleFrame = null;

    // Get first slide of a presentation
    ISlide slide = pres.Slides[0];

    // Traversing all shapes for OLE frame
    foreach (IShape shape in slide.Shapes)
    {
        if (shape is OleObjectFrame)
        {
            oleFrame = (OleObjectFrame)shape;
        }
    }

    if (oleFrame != null)
    {
        // Create a file name with type of an embedded data
        string embeddedFile = "EmbeddedData." + oleFrame.EmbeddedData.EmbeddedFileExtension;

        // Save embedded data to a file
        File.WriteAllBytes(embeddedFile, oleFrame.EmbeddedData.EmbeddedFileData);

        // Create new data for embedding in OLE object
        byte[] data = File.ReadAllBytes("book1.xlsx");
        IOleEmbeddedDataInfo newData = new OleEmbeddedDataInfo(data, "xlsx");
        
        // Change embedding data in OleObjectFrame
        oleFrame.SetEmbeddedData(newData);
    }

    pres.Save("OleEdit_out.pptx", SaveFormat.Pptx);
}

Please note that properties ObjectData, EmbeddedFileExtension and EmbeddedFileData of IOleObjectFrame interface marked as obsolete now so please use IOleObjectFrame.SetEmbeddedData method and IOleObjectFrame.EmbeddedData property instead of them. These obsolete properties will be removed after the release of version 21.11.

New overloadings for the SlideUtil.AlignShapes method have been added

Method SlideUtil.AlignShapes (ShapesAlignmentType alignmentType, bool alignToSlide, IBaseSlide slide) has been added.

This overloading allows aligning all shapes within IBaseSlide.

using (Presentation pres = new Presentation())
{
   ISlide slide = pres.Slides[0];
   IAutoShape shape1 = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 100, 100, 100, 100);
   IAutoShape shape2 = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 200, 200, 100, 100);
   IAutoShape shape3 = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 300, 300, 100, 100);
   SlideUtil.AlignShapes(ShapesAlignmentType.AlignBottom, true, pres.Slides[0]);
   pres.Save("output.pptx", SaveFormat.Pptx);
}

Method SlideUtil.AlignShapes (ShapesAlignmentType alignmentType, bool alignToSlide, IGroupShape shapes) has been added.

This overloading allows aligning all shapes within IGroupShape.

using (Presentation pres = new Presentation())
{
   ISlide slide = pres.Slides[0];
   IGroupShape groupShape = slide.Shapes.AddGroupShape(); 
   groupShape.Shapes.AddAutoShape(ShapeType.Rectangle, 350, 50, 50, 50);
   groupShape.Shapes.AddAutoShape(ShapeType.Rectangle, 450, 150, 50, 50);
   groupShape.Shapes.AddAutoShape(ShapeType.Rectangle, 550, 250, 50, 50);
   groupShape.Shapes.AddAutoShape(ShapeType.Rectangle, 650, 350, 50, 50);
   SlideUtil.AlignShapes(ShapesAlignmentType.AlignLeft, false, groupShape);
   pres.Save("output.pptx", SaveFormat.Pptx);
}

Method SlideUtil.AlignShapes (ShapesAlignmentType alignmentType, bool alignToSlide, IGroupShape shapes, int[] shapeIndexes) has been added.

This overloading allows aligning shapes with specified indexes within IGroupShape.

using (Presentation pres = new Presentation())
{
   ISlide slide = pres.Slides[0];
   IGroupShape groupShape = slide.Shapes.AddGroupShape(); 
   groupShape.Shapes.AddAutoShape(ShapeType.Rectangle, 350, 50, 50, 50);
   groupShape.Shapes.AddAutoShape(ShapeType.Rectangle, 450, 150, 50, 50);
   groupShape.Shapes.AddAutoShape(ShapeType.Rectangle, 550, 250, 50, 50);
   groupShape.Shapes.AddAutoShape(ShapeType.Rectangle, 650, 350, 50, 50);
   SlideUtil.AlignShapes(ShapesAlignmentType.AlignLeft, false, groupShape, new int[] { 0, 2 });
   pres.Save("output.pptx", SaveFormat.Pptx);
}
