IRenderingOptions

IRenderingOptions class

Provides options that control how a presentation/slide is rendered.

class IRenderingOptions : public virtual Aspose::Slides::Export::ISaveOptions

Methods

Method	Description
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.
virtual System::String get_DefaultRegularFont()	Returns font used in case source font is not found. Reads System::String.
virtual Aspose::Slides::GradientStyle get_GradientStyle()	Returns the visual style of the gradient. Read GradientStyle.
virtual System::SharedPtr<IInkOptions> get_InkOptions()	Provides options that control the look of Ink objects in exported document. Read-only IInkOptions
virtual System::SharedPtr<IProgressCallback> get_ProgressCallback()	Represents a callback object for saving progress updates in percentage. See IProgressCallback.
virtual System::SharedPtr<ISlidesLayoutOptions> get_SlidesLayoutOptions()	Gets the mode in which slides are placed on the page when exporting a presentation ISlidesLayoutOptions.
virtual System::SharedPtr<Aspose::Slides::Warnings::IWarningCallback> get_WarningCallback()	Returns an object which receives warnings and decides whether loading process will continue or will be aborted. Read Aspose::Slides::Warnings::IWarningCallback.
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.
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 set_DefaultRegularFont(System::String)	Sets font used in case source font is not found. Writes System::String.
virtual void set_GradientStyle(Aspose::Slides::GradientStyle)	Sets the visual style of the gradient. Write GradientStyle.
virtual void set_ProgressCallback(System::SharedPtr<IProgressCallback>)	Represents a callback object for saving progress updates in percentage. See IProgressCallback.
virtual void set_SlidesLayoutOptions(System::SharedPtr<ISlidesLayoutOptions>)	Sets the mode in which slides are placed on the page when exporting a presentation ISlidesLayoutOptions.
virtual void set_WarningCallback(System::SharedPtr<Aspose::Slides::Warnings::IWarningCallback>)	Sets an object which receives warnings and decides whether loading process will continue or will be aborted. Write Aspose::Slides::Warnings::IWarningCallback.
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.

notesCommentsLayoutingOptions->set_NotesPosition(NotesPositions::BottomTruncated);

System::SharedPtr<IRenderingOptions> renderingOpts = System::MakeObject<RenderingOptions>();
renderingOpts->set_SlidesLayoutOptions(notesCommentsLayoutingOptions);

System::Shared_Ptr<ISlide> slide = pres->get_Slide(0);

slide->GetThumbnail(renderingOpts)->Save(u"pres-Original.png", ImageFormat::get_Png());

renderingOpts->set_DefaultRegularFont(u"Arial Black");
slide->GetThumbnail(renderingOpts)->Save(u"pres-ArialBlackDefault.png", ImageFormat::get_Png());

renderingOpts->set_DefaultRegularFont(u"Arial Narrow");
slide->GetThumbnail(renderingOpts)->Save(u"pres-ArialNarrowDefault.png", ImageFormat::get_Png());
