Methods
| Method | Description |
|---|---|
| System::SharedPtr<IPresentation> CreatePresentation() override | Creates new presentation. |
| System::SharedPtr<IPresentation> CreatePresentation(System::SharedPtr<ILoadOptions>) override | Creates new presentation with additional load options |
| 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. |
| static System::SharedPtr<PresentationFactory> get_Instance() | Presentation factory static instance. Read-only PresentationFactory. |
| 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. |
| System::SharedPtr<IPresentationInfo> GetPresentationInfo(System::String) override | Creates new PresentationInfo object from file and binds presentation to it. |
| System::SharedPtr<IPresentationInfo> GetPresentationInfo(System::SharedPtr<System::IO::Stream>) override | Creates new PresentationInfo object from stream and binds presentation to it. Gets info about presentation in specified stream. |
| System::SharedPtr<IPresentationText> GetPresentationText(System::String, TextExtractionArrangingMode) override | Retrieves the raw text from the slides |
| System::SharedPtr<IPresentationText> GetPresentationText(System::SharedPtr<System::IO::Stream>, TextExtractionArrangingMode) override | Retrieves the raw text from the slides |
| System::SharedPtr<IPresentationText> GetPresentationText(System::SharedPtr<System::IO::Stream>, TextExtractionArrangingMode, System::SharedPtr<ILoadOptions>) override | Retrieves the raw text from the slides |
| 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. |
| System::SharedPtr<IPresentation> ReadPresentation(System::ArrayPtr<uint8_t>) override | Reads an existing presentation from array |
| System::SharedPtr<IPresentation> ReadPresentation(System::ArrayPtr<uint8_t>, System::SharedPtr<ILoadOptions>) override | Reads an existing presentation from array with additional load options |
| System::SharedPtr<IPresentation> ReadPresentation(System::SharedPtr<System::IO::Stream>) override | Reads an existing presentation from stream |
| System::SharedPtr<IPresentation> ReadPresentation(System::SharedPtr<System::IO::Stream>, System::SharedPtr<ILoadOptions>) override | Reads an existing presentation from stream with additional load options |
| System::SharedPtr<IPresentation> ReadPresentation(System::String) override | Reads an existing presentation from file |
| System::SharedPtr<IPresentation> ReadPresentation(System::String, System::SharedPtr<ILoadOptions>) override | Reads an existing presentation from stream with additional load options |
| 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. |
Remarks
The following example shows how to checking a Presentation Format.
System::SharedPtr<IPresentationInfo> info = PresentationFactory::get_Instance()->GetPresentationInfo(u"pres.pptx");
System::Console::WriteLine(System::ExplicitCast<System::Object>(info->get_LoadFormat())); // PPTX
System::SharedPtr<IPresentationInfo> info2 = PresentationFactory::get_Instance()->GetPresentationInfo(u"pres.ppt");
System::Console::WriteLine(System::ExplicitCast<System::Object>(info2->get_LoadFormat())); // PPT
System::SharedPtr<IPresentationInfo> info3 = PresentationFactory::get_Instance()->GetPresentationInfo(u"pres.odp");
System::Console::WriteLine(System::ExplicitCast<System::Object>(info3->get_LoadFormat())); // ODP
The following example shows how to getting the properties of a Presentation.
System::SharedPtr<IPresentationInfo> info = PresentationFactory::get_Instance()->GetPresentationInfo(u"pres.pptx");
System::SharedPtr<IDocumentProperties> props = info->ReadDocumentProperties();
System::Console::WriteLine(System::ExplicitCast<System::Object>(props->get_CreatedTime()));
System::Console::WriteLine(props->get_Subject());
System::Console::WriteLine(props->get_Title());
The following example shows how to updating the properties of a Presentation.
System::SharedPtr<IPresentationInfo> info = PresentationFactory::get_Instance()->GetPresentationInfo(u"pres.pptx");
System::SharedPtr<IDocumentProperties> props = info->ReadDocumentProperties();
props->set_Title(u"My title");
info->UpdateDocumentProperties(props);
