Methods

MethodDescription
void Dispose() overrideDisposes the instance of the PresentationAnimationsGenerator.
virtual bool Equals(ptr)Compares objects using C# Object.Equals semantics.
static std::enable_if<IsSmartPtr<T1>::value&&IsSmartPtr<T2>::value, bool>::type Equals(T1 const&, T2 const&)Compares reference type objects in C# style.
static std::enable_if<!IsSmartPtr<T1>::value&&!IsSmartPtr<T2>::value, bool>::type Equals(T1 const&, T2 const&)Compares value type objects in C# style.
static bool Equals(float const&, float const&)Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN.
static bool Equals(double const&, double const&)Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN.
virtual bool FastCast(const Details::FastRttiBase&, void **) constFor internal purposes only.
int32_t get_DefaultDelay() constGets default delay time [ms].
int32_t get_ExportedSlides() constGet the number of the exported slides count.
bool get_IncludeHiddenSlides() constGet or sets if hidden slides should be included.
Detail::SmartPtrCounter * GetCounter()Gets reference counter data structure associated with the object.
virtual int32_t GetHashCode() constAnalog of C# Object.GetHashCode() method. Enables hashing of custom objects.
virtual const TypeInfo& GetType() constGets actual type of object. Analog of C# System.Object.GetType() call.
virtual bool Is(const TypeInfo&) constCheck if object represents an instance of type described by targetType. Analog of C# ‘is’ operator.
void Lock()Implements C# lock() statement locking. Call directly or use LockContext sentry object.
virtual ptr MemberwiseClone() constAnalog of C# Object.MemberwiseClone() method. Enables cloning custom types.
Object()Creates object. Initializes all internal data structures.
Object(Object const&)Copy constructor. Doesn’t copy anything, really, just initializes new object and enables copy constructing subclasses.
Object& operator=(Object const&)Assignment operator. Doesn’t copy anything, really, just initializes new object and enables copy constructing subclasses.
PresentationAnimationsGenerator(System::SharedPtr<Presentation>)Creates a new instance of the PresentationAnimationsGenerator.
PresentationAnimationsGenerator(System::Drawing::Size)Creates a new instance of the PresentationAnimationsGenerator.
static bool ReferenceEquals(ptr const&, ptr const&)Compares objects by reference.
static std::enable_if<!IsSmartPtr<T>::value, bool>::type ReferenceEquals(T const&, T const&)Compares objects by reference.
static std::enable_if<!IsSmartPtr<T>::value, bool>::type ReferenceEquals(T const&, std::nullptr_t)Reference-compares value type object with nullptr.
bool ReferenceEquals(String const&, std::nullptr_t)Specialization of Object::ReferenceEquals for case of string and nullptr.
bool ReferenceEquals(String const&, String const&)Specialization of Object::ReferenceEquals for case of strings.
int RemovedSharedRefs(int)Decreases shared reference count by specified value.
void Run(System::SharedPtr<System::Collections::Generic::IEnumerable<System::SharedPtr<ISlide>>>)Run the animation events generation for each slide.
void Run(System::SharedPtr<System::Collections::Generic::IEnumerable<System::SharedPtr<ISlide>>>, int32_t, PresentationPlayer::FrameTickHandler)Run the animation events generation for each slide.
void set_DefaultDelay(int32_t)Sets default delay time [ms].
void set_IncludeHiddenSlides(bool)Get or sets if hidden slides should be included.
virtual void SetTemplateWeakPtr(uint32_t)Set n’th template argument a weak pointer (rather than shared). Allows switching pointers in containers to weak mode.
int SharedCount() constGets current value of shared reference counter.
Object * SharedRefAdded()Increments shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
int SharedRefRemovedSafe()Decrements and returns shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
virtual String ToString() constAnalog of C# Object.ToString() method. Enables converting custom objects to string.
static const TypeInfo& Type()Implements C# typeof(System.Object) construct.
void Unlock()Implements C# lock() statement unlocking. Call directly or use LockContext sentry object.
Detail::SmartPtrCounter * WeakRefAdded()Increments weak reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
void WeakRefRemoved()Decrements weak reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
virtual ~Object()Destroys object. Frees all internal data structures.

Remarks

void OnFrameTick(System::SharedPtr<PresentationPlayer> sender, System::SharedPtr<FrameTickEventArgs> args)
{
    args->GetFrame()->Save(System::String::Format(u"frame_{0}.png", sender->get_FrameIndex()), System::Drawing::Imaging::ImageFormat::get_Png());
}

void SaveFrames()
{
    const int32_t FPS = 30;

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

    auto player = System::MakeObject<PresentationPlayer>(animationsGenerator, FPS);
    player->FrameTick += OnFrameTick;

    animationsGenerator->Run(presentation->get_Slides());
}
