class PresentationPlayer : public System::IDisposable
Methods
Method | Description |
---|---|
void Dispose() override | Disposes the instance of the PresentationPlayer. |
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 **) const | For internal purposes only. |
int32_t get_FrameIndex() | Gets the frame index. |
Detail::SmartPtrCounter * GetCounter() | Gets reference counter data structure associated with the object. |
virtual int32_t GetHashCode() const | Analog of C# Object.GetHashCode() method. Enables hashing of custom objects. |
virtual const TypeInfo& GetType() const | Gets actual type of object. Analog of C# System.Object.GetType() call. |
virtual bool Is(const TypeInfo&) const | Check 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() const | Analog 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. |
PresentationPlayer(System::SharedPtr<PresentationAnimationsGenerator>, double) | Creates new instance of the PresentationPlayer. |
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. |
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() const | Gets 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() const | Analog 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. |

FrameTickHandler | Represents the frame tick handler of PresentationPlayer::FrameTick event. |
Remarks
auto pres = System::MakeObject<Presentation>(u"pres.pptx");
auto animationsGenerator = System::MakeObject<PresentationAnimationsGenerator>(pres);
// Play animation with 33 FPS
System::SharedPtr<PresentationPlayer> player1 = System::MakeObject<PresentationPlayer>(animationsGenerator, 33);
player1->FrameTick.connect(static_cast<std::function<void(System::SharedPtr<PresentationPlayer>, System::SharedPtr<FrameTickEventArgs>)>>(
[](System::SharedPtr<PresentationPlayer> sender, System::SharedPtr<FrameTickEventArgs> args) -> void
{
args->GetFrame()->Save(System::IO::Path::Combine(u"33fps", System::String::Format(u"frame_{0}.png", sender->get_FrameIndex())));
}));
animationsGenerator->Run(pres->get_Slides());
// Play animation with 45 FPS
System::SharedPtr<PresentationPlayer> player2 = System::MakeObject<PresentationPlayer>(animationsGenerator, 45);
player2->FrameTick.connect(static_cast<std::function<void(System::SharedPtr<PresentationPlayer>, System::SharedPtr<FrameTickEventArgs>)>>(
[](System::SharedPtr<PresentationPlayer> sender, System::SharedPtr<FrameTickEventArgs> args) -> void
{
args->GetFrame()->Save(System::IO::Path::Combine(u"45fps", System::String::Format(u"frame_{0}.png", sender->get_FrameIndex())));
}));
animationsGenerator->Run(pres->get_Slides());
