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 declaration:

/// <summary>
/// Options that control how a XAML document is saved.
/// </summary>
class IXamlOptions : public virtual Aspose::Slides::Export::ISaveOptions
{
public:
    /// <summary>
    /// Determines whether hidden slides will be exported.
    /// </summary>
    virtual bool get_ExportHiddenSlides() = 0;
    /// <summary>
    /// Determines whether hidden slides will be exported.
    /// </summary>
    virtual void set_ExportHiddenSlides(bool value) = 0;
    /// <summary>
    /// Represents an implementation of IOutputSaver interface.
    /// </summary>
    virtual System::SharedPtr<IXamlOutputSaver> get_OutputSaver() = 0;
    /// <summary>
    /// Represents an implementation of IOutputSaver interface.
    /// </summary>
    virtual void set_OutputSaver(System::SharedPtr<IXamlOutputSaver> value) = 0;
};

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

void Save(System::SharedPtr<Export::Xaml::IXamlOptions> options);

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

auto pres = System::MakeObject<Presentation>(u"pres.pptx");
SharedPtr<IXamlOptions> options = System::MakeObject<XamlOptions>();
options->set_ExportHiddenSlides(true);
pres->Save(options);

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

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

/// <summary>
/// Represents an output saver implementation for transfer data to the external storage.
/// </summary>
class IXamlOutputSaver : public System::Object
{
public:
    /// <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>
    virtual void Save(System::String path, System::ArrayPtr<uint8_t> data) = 0;
};

IEffect::get_TargetShape() method has been added

The IEffect::get_TargetShape() method has been added. It returns the shape affected by the effect.

Method declaration:

/// <summary>
/// Returns target shape for effect.
/// Read-only <see cref="IShape"></see>.
/// </summary>
virtual System::SharedPtr<IShape> get_TargetShape() = 0;

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

auto pres = System::MakeObject<Presentation>(u"SomePresentation.pptx");
for (auto slide : System::IterateOver(pres->get_Slides()))
{
    for (auto effect : System::IterateOver(slide->get_Timeline()->get_MainSequence()))
    {
        System::Console::WriteLine(u"{0} animation effect is set to shape #{1} on slide #{2}", 
            effect->get_Type(), effect->get_TargetShape()->get_UniqueId(), slide->get_SlideNumber());
    }
}
