ImageFormat

ImageFormat class

Represents the file format of an image. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.

class ImageFormat : public System::Object

Methods

MethodDescription
bool Equals(ImageFormatPtr) constDetermines if the image formats represented by the current and specified objects are equal.
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 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.
static ImageFormatPtr get_Bmp()Returns a shared pointer to an ImageFormat object that represents the bitmap image format.
static ImageFormatPtr get_Emf()Returns a shared pointer to an ImageFormat object that represents the enhanced metafile format.
static ImageFormatPtr get_Exif()Returns a shared pointer to an ImageFormat object that represents the Exchangeable Image File (Exif) format.
static ImageFormatPtr get_Gif()Returns a shared pointer to an ImageFormat object that represents the Graphics Interchange Format (GIF) image format.
System::Guid get_Guid() constReturns the GUID associated with the image format represented by the current object.
static ImageFormatPtr get_Icon()Returns a shared pointer to an ImageFormat object that represents the Windows icon image format.
static ImageFormatPtr get_Jpeg()Returns a shared pointer to an ImageFormat object that represents the Joint Photographic Experts Group (JPEG) image format.
static ImageFormatPtr get_MemoryBmp()Returns a shared pointer to an ImageFormat object that represents the format of a bitmap in memory.
static ImageFormatPtr get_Png()Returns a shared pointer to an ImageFormat object that represents the W3C Portable Network Graphics (PNG) image format.
static ImageFormatPtr get_Tiff()Returns a shared pointer to an ImageFormat object that represents the Tagged Image File Format (TIFF) image format.
static ImageFormatPtr get_Wmf()Returns a shared pointer to an ImageFormat object that represents the Windows metafile (WMF) image format.
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.
ImageFormat(const System::Guid&)Constructs an instance of ImageFormat class that represents an image format format associated with the specified GUID.
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.
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() 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 System::String ToString() constConverts this ImageFormat object to a human-readable 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.
