Description
Provides access to the Windows GDI bitmap handle for accessing the GDI bitmap object.
Use Handle to call a Windows API function that requires the handle of a bitmap object (HBITMAP). Pass Handle as the bitmap handle parameter to these functions.
Handle is the HBITMAP encapsulated by the bitmap object. Avoid grabbing the handle directly since it causes the HBITMAP to be copied if more than one TBitmap shares the handle.
Warning: Be careful when giving the handle to an object or routine. If the receiver takes ownership (and destroys) the bitmap handle, call ReleaseHandle.
