InheritedProtected
_AddRefprotectedIncrements the reference count for the interfaced object's interface.
_ReleaseprotectedDecrements the reference count for the interfaced object's interface.
AfterConstructionpublicObtains a reference to the Owner's interface.
AssignpublicCopies a new bitmap image to the bitmap object.
AssignToprotectedCopies the properties of an object to a destination object.
BeforeDestructionpublicResponds before the first destructor executes.
CanLoadFromStreampublic
Changedprotected
CheckDisposedprotected
ClassInfopublicReturns a pointer to the run-time type information (RTTI) table for the object type.
ClassNamepublicReturns a string indicating the type of the object instance (as opposed to the type of the variable passed as an argument).
ClassNameIspublicDetermines whether an object is of a specific type.
ClassParentpublicReturns the type of the immediate ancestor of a class.
ClassTypepublicReturns the class reference for the object's class.
CleanupInstancepublicPerforms finalization on long strings, variants, and interface variables within a class.
CreatepublicInstantiates a bitmap object.
DefaultHandlerpublicProvides the interface for a method that processes message records.
DefinePropertiesprotectedSet virtual property for reading and writing graphic data stream.
DestroypublicDisposes of the instance of the bitmap object.
DispatchpublicCalls message-handling methods for the object, based on the contents of the Message parameter.
DisposeOfpublicDisposeOf forces the execution of the destructor code in an object.
DormantpublicCreates a memory bitmap image in order to release the bitmap handle, forcing the image into DIB format to save resources.
Drawprotected
DrawTransparentprotected
EqualspublicCompare graphic to another TGraphic object and return true if objects contain same graphic.
FieldAddresspublicReturns the address of a published object field.
FreepublicDestroys an object and frees its associated memory, if necessary.
FreeImagepublicFrees the cached file image stored in memory by the bitmap.
FreeInstancepublicDeallocates memory allocated by a previous call to the NewInstance method.
GetDisposedprotectedGetter for the Disposed property.
GetEmptyprotected
GetHashCodepublicReturns an integer containing the hash code.
GetHeightprotected
GetInterfacepublicRetrieves a specified interface.
GetInterfaceEntrypublicReturns the entry for a specific interface implemented in a class.
GetInterfaceTablepublicReturns a pointer to a structure containing all of the interfaces implemented by a given class.
GetNamePathpublicReturns the name of the object as it appears in the Object Inspector.
GetOwnerprotectedReturns the owner of an object.
GetPaletteprotected
GetSupportsPartialTransparencyprotected
GetTransparentprotectedSpecifies if graphic is drawn transparently.
GetWidthprotected
HandleAllocatedpublicIndicates whether the TBitmap object has acquired a handle to the underlying GDI object.
HandleNeededprotectedCreate GDI bitmap for TBitmap if it doesn't already exist.
InheritsFrompublicDetermines the relationship of two object types.
InitInstancepublicInitializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer.
InstanceSizepublicReturns the size in bytes of each instance of the object type.
LoadFromClipboardFormatpublicLoads a bitmap from the Clipboard into the bitmap object.
LoadFromFilepublicLoads a graphic image stored in a file.
LoadFromResourceIDpublicLoads a bitmap from a resource into the bitmap object.
LoadFromResourceNamepublicLoads a bitmap resource into the bitmap object.
LoadFromStreampublicLoads the bitmap from a stream into the bitmap object.
MaskpublicConverts the current bitmap image into a monochrome mask, replacing TransparentColor with white and every other color with black.
MaskHandleNeededprotectedCreate GDI bitmap for TBitmap's mask if it doesn't already exist.
MethodAddresspublicReturns the address of a class method by name.
MethodNamepublicReturns the name of a class method by address.
NewInstancepublicAllocates memory for an instance of an object type and returns a pointer to that new instance.
operator ()public
PaletteNeededprotectedCreate color palette for TBitmap's mask if it doesn't already exist.
ProgressprotectedGenerate OnProgress event when graphic is changing.
QualifiedClassNamepublicReturns the qualified name of the class.
QueryInterfacepublicReturns a reference to a specified interface if the object supports that interface.
ReadDataprotected
ReleaseHandlepublicReturns the handle to the bitmap so that the TBitmap object no longer knows about the handle.
ReleaseMaskHandlepublicReturns the handle to the bitmap's mask so that the TBitmap object no longer knows about the mask handle.
ReleasePalettepublicReturns the handle to the bitmap's palette and disassociates the palette from the TBitmap object.
SafeCallExceptionpublicHandles exceptions in methods declared using the safecall calling convention.
SaveToClipboardFormatpublicCreates a local copy of the bitmap in Clipboard format.
SaveToFilepublicSaves a graphics image to a file.
SaveToStreampublicSaves the bitmap to a stream.
SetHeightprotected
SetPaletteprotected
SetSizepublicSpecifies the size of the bitmap.
SetTransparentprotectedSpecify if graphic should be drawn transparently.
SetWidthprotected
ToStringpublicReturns a string containing the class name.
UnitNamepublicReturns the name of the unit where the class is defined.
UnitScopepublicReturns the class's unit scope.
