Public API Changes

Support of Presentation to XAML export

To support Presentation export to XAML, we added new API members.

IXamlOptions interface and XamlOptions class. IXamlOptions definition:

/// <summary>
/// Options that control how a XAML document is saved.
/// </summary>
/// <example>
/// <code>
/// [C#]
/// using (Presentation pres = new Presentation("pres.pptx"))
/// {
/// 	pres.Save(new XamlOptions { ExportHiddenSlides = true });
/// }
/// </code>
/// </example>    
public interface IXamlOptions : ISaveOptions
{
    /// <summary>
    /// Determines whether hidden slides will be exported.
    /// </summary>
    /// <example>
    /// <code>
    /// [C#]
    /// using (Presentation pres = new Presentation("pres.pptx"))
    /// {
    /// 	pres.Save(new XamlOptions { ExportHiddenSlides = true });
    /// }
    /// </code>
    /// </example>        
    bool ExportHiddenSlides { get; set; }
    
    /// <summary>
    /// Represents an implementation of IOutputSaver interface.
    /// </summary>
    IXamlOutputSaver OutputSaver { get; set; }
}

For Presentation export to XAML, a new Save method overload got added to the Presentation class:

public void Save(IXamlOptions options);

This code sample demonstrates the exporting of a Presentation to a set of XAML files:

using (Presentation pres = new Presentation("pres.pptx"))
{
    pres.Save(new XamlOptions { ExportHiddenSlides = true });
}

The XAML files get saved in a newly created folder—“pres”.

The IXamlOutputSaver interface allows you to define your own output-saving service. IXamlOutputSaver definition:

/// <summary>
/// Represents an output saver implementation for transfer data to the external storage.
/// </summary>
public interface IXamlOutputSaver
{
    /// <summary>
    /// Saves a bytes array to a destination location.
    /// </summary>
    /// <param name="path">The destination path.</param>
    /// <param name="data">A binary data for saving to a destination location.</param>
    void Save(string path, byte[] data);
}

IEffect.TargetShape property has been added

The Aspose.Slides.Animation.IEffect.TargetShape property has been added. It returns the shape affected by the effect.

Property declaration:

/// <summary>
/// Returns target shape for effect.
/// Read-only <see cref="IShape"/>.
/// </summary>
IShape TargetShape { get; }

This code sample demonstrates the output of information for all animated shapes in the main sequence for all slides in a presentation.

using (Presentation pres = new Presentation("SomePresentation.pptx"))
{
    foreach (ISlide slide in pres.Slides)
        foreach (IEffect effect in slide.Timeline.MainSequence)
            Console.WriteLine(effect.Type + " animation effect is set to shape#" + effect.TargetShape.UniqueId + " on slide#" + slide.SlideNumber);
}

Aspose.Slides.Export.Web.* interfaces were removed

These interfaces were removed from the Aspose.Slides.Export.Web namespace:

string Compile<TModel>(string key, TModel model);

Was replaced with

string Compile(string key, object model);

Storage.ContainsKey method has been added

The Aspose.Slides.Export.Web.Storage.ContainsKey method has been added. It allows you to check whether some value with a certain key was added to the storage.

Method declaration:

/// <summary>
/// Determines whether the storage contains an element with the specified key.
/// </summary>
/// <param name="key">Key of the value.</param>
/// <returns>True if the storage contains an element with the specified key, false otherwise.</returns>
public bool ContainsKey(string key)
{
   ...
}

A sample code—an example of Aspose.Slides.WebExtensions template—that shows you how to use the new method:

@model TemplateContext<AutoShape>

@{
    AutoShape contextObject = Model.Object;

    string id = "slide-" + contextObject.Slide.SlideId + "-shape-" + contextObject.UniqueId;

    string animationAttributes = "";
    if (Model.Local.ContainsKey("animationAttributes"))
    {
        animationAttributes = Model.Local.Get<string>("animationAttributes");
    }
}

@{
    <div class="shape" id="@id" @Raw(animationAttributes)>
        @{
            var subModel = Model.SubModel((TextFrame)contextObject.TextFrame);
            @Include("textframe", subModel)        
        }
    </div>
}

WebDocumentOptions.AnimateShapes property has been added

The Aspose.Slides.Export.Web.WebDocumentOptions.AnimateShapes property has been added. When the property is set to true, shape animations get added to exported HTML results.

This code sample demonstrates how the property can be used in a project based on Aspose.Slides.WebExtensions:

using (Presentation pres = new Presentation(@"SomePresentation.pptx"))
{
    WebDocumentOptions opts = new WebDocumentOptions() { EmbedImages = false , AnimateTransitions = true, AnimateShapes = true };
    pres.ToSinglePageWebDocument(opts, @"templates\single-page", @"single-page-presentation").Save();
}
