Public API Changes

New GetSubstitutions() method 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 on the presentation's rendering.
/// </summary>
/// <returns>Collection of all fonts substitution <see cref="Aspose::Slides::FontSubstitutionInfo">FontSubstitutionInfo</see>.</returns>
/// <example>
System::SharedPtr<System::Collections::Generic::IEnumerable<System::SharedPtr<FontSubstitutionInfo>>> GetSubstitutions();

FontSubstitutionInfo class declaration:

/// <summary>
/// This class represents information about the font replacement when it will be rendered.
/// </summary>
class FontSubstitutionInfo : public System::Object
{
public:
    /// <summary>
    /// Indicates source font name in presentation.
    /// Read-only <see cref="System::String"></see>
    /// </summary>
    System::String get_OriginalFontName();
	
    /// <summary>
    /// Indicates the replacement font name for the original font.
    /// Read-only <see cref="System::String"></see>
    /// </summary>
    System::String get_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:

auto pres = System::MakeObject<Presentation>(u"pres.pptx");

for (auto fontSubstitution : pres->get_FontsManager()->GetSubstitutions())
{
    System::Console::WriteLine(u"{0} -> {1}", fontSubstitution->get_OriginalFontName(), fontSubstitution->get_SubstitutedFontName());
}

New Animation Timing properties have been added

These new methods have been added to the Timing class - get_RepeatUntilEndSlide(), set_RepeatUntilEndSlide(), get_RepeatUntilNextClick() and set_RepeatUntilNextClick().

Methods declaration:

/// <summary>
/// This attribute specifies if the effect will repeat until the end of the slide.
/// Read <see cref="bool"></see>.
/// </summary>
bool get_RepeatUntilEndSlide();

/// <summary>
/// This attribute specifies if the effect will repeat until the end of the slide.
/// Write <see cref="bool"></see>.
/// </summary>
void set_RepeatUntilEndSlide(bool value);

/// <summary>
/// This attribute specifies if the effect will repeat until the next click.
/// Read <see cref="bool"></see>.
/// </summary>

bool get_RepeatUntilNextClick();

/// <summary>
/// This attribute specifies if the effect will repeat until the next click.
/// Write <see cref="bool"></see>.
/// </summary>
void set_RepeatUntilNextClick(bool value);

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

auto presentation = System::MakeObject<Presentation>(u"demo.pptx");

// Gets the effects sequence for the first slide
System::SharedPtr<ISequence> effectsSequence = presentation->get_Slides()->idx_get(0)->get_Timeline()->get_MainSequence();

// Gets the first effect of main sequence.
System::SharedPtr<IEffect> effect = effectsSequence->idx_get(0);

// Changes effect Timing/Repeat to "Until End of Slide"
effect->get_Timing()->set_RepeatUntilEndSlide(true);
