Public API Changes

New method GetSubstitutions has been added to the IFontsManager interface

GetSubstitutions, a new method, has been added to the IFontsManager interface and FontsManager class.

The GetSubstitutions method can be used to get information about fonts that will be replaced when a presentation is rendered.

Method declaration:

/// <summary>
/// Gets the information about fonts that will be replaced when the presentation is rendered.
/// </summary>
/// <returns>Collection of all fonts substitution <see cref="FontSubstitutionInfo"/>in the presentation rendering process</returns>
IEnumerable<FontSubstitutionInfo> GetSubstitutions();

/// <summary>
/// This structure represents information about the font replacement when it will be rendered.
/// </summary>
public class FontSubstitutionInfo
{
    /// <summary>
    /// Indicates source font name in presentation.
    /// Read-only <see cref="string"/>
    /// </summary>
    public string OriginalFontName

    /// <summary>
    /// Indicates replacement font name for the original font.
    /// Read-only <see cref="string"/>
    /// </summary>
    public string SubstitutedFontName
}

This C# code shows you how the GetSubstitutions method is used to get all fonts that will be substituted when a presentation is rendered:

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

New Animation Timing properties were added - RepeatUntilEndSlide and RepeatUntilNextClick

These new properties have been added to the Timing class: RepeatUntilEndSlide and RepeatUntilNextClick.

Properties declaration:

/// <summary>
/// This attribute specifies whether the effect will be repeated until the end of the slide.
/// Read/write <see cref="bool"/>.
/// </summary>
/// <example>
/// <code>
/// [C#]
/// 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;
/// }
/// </code>
/// </example>
bool RepeatUntilEndSlide { get; set; }

/// <summary>
/// This attribute specifies whether the effect will be repeated until the next click.
/// Read/write <see cref="bool"/>.
/// </summary>
/// <example>
/// <code>
/// 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 Next Click"
///     effect.Timing.RepeatUntilNextClick = true;
/// }
/// </code>
/// </example>
bool RepeatUntilNextClick { get; set; }

Example that shows how to change an effect Timing/Repeat setting to “Until End of Slide”:

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;
}
