Name 
Description 
 
Increments the reference count for this interface. 
 
Decrements the reference count for this interface. 
 
Obtains a reference to the Owner's interface. 
 
Responds after the last constructor has executed. 
 
Copies a new bitmap image to the bitmap object. 
 
Responds before the first destructor executes. 
 
Returns a pointer to the runtime type information (RTTI) table for the object type. 
 
Returns a string indicating the type of the object instance (as opposed to the type of the variable passed as an argument). 
 
Determines whether an object is of a specific type. 
 
Returns the type of the immediate ancestor of a class. 
 
Returns the class reference for the object's class. 
 
Performs finalization on long strings, variants, and interface variables within a class. 
 
Instantiates a bitmap object. 
 
Provides the interface for a method that processes message records. 
 
Disposes of the instance of the bitmap object. 
 
Calls message-handling methods for the object, based on the contents of the Message parameter. 
 
Creates a memory bitmap image in order to release the bitmap handle, forcing the image into DIB format to save resources. 
 
Returns the address of a published object field. 
 
Free 
Destroys an object and frees its associated memory, if necessary. 
 
Frees the cached file image stored in memory by the bitmap. 
 
Deallocates memory allocated by a previous call to the System::TObject::NewInstance method. 
 
Retrieves a specified interface. 
 
Returns the entry for a specific interface implemented in a class. 
 
Returns a pointer to a structure containing all of the interfaces implemented by a given class. 
 
Returns the name of the object as it appears in the Object Inspector. 
 
Indicates whether the TBitmap object has acquired a handle to the underlying GDI object. 
 
Determines the relationship of two object types. 
 
Initializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer. 
 
Returns the size in bytes of each instance of the object type. 
 
Loads a bitmap from the Clipboard into the bitmap object. 
 
Loads a graphic image stored in a file. 
 
Loads a bitmap from a resource into the bitmap object. 
 
Loads a bitmap resource into the bitmap object. 
 
Loads the bitmap from a stream into the bitmap object. 
 
Mask 
Converts the current bitmap image into a monochrome mask, replacing TransparentColor with white and every other color with black. 
 
This is MethodAddress, a member of class TObject. 
 
This is MethodName, a member of class TObject. 
 
Allocates memory for an instance of an object type and returns a pointer to that new instance. 
 
Returns a reference to a specified interface if the object supports that interface. 
 
Returns a reference to a specified interface if the object supports that interface. 
 
Returns the handle to the bitmap so that the TBitmap object no longer knows about the handle. 
 
Returns the handle to the bitmap's mask so that the TBitmap object no longer knows about the mask handle. 
 
Returns the handle to the bitmap's palette and disassociates the palette from the TBitmap object. 
 
Handles exceptions in methods declared using the safecall calling convention. 
 
Creates a local copy of the bitmap in Clipboard format. 
 
Saves a graphics image to a file. 
 
Saves the bitmap to a stream. 
 
Specifies the size of the bitmap.
