This structure is used in the callback function with L_AnnEnumerateHandles.

Member	Description
uStructSize	Size of this structure. Use sizeof(ANNHANDLEINFO)
nType	Type of handle. Possible values are:
	Value	Meaning
	ANNHANDLETYPE_DEFAULT_HANDLE	A default annotation handle.
	ANNHANDLETYPE_USER_HANDLE	A user-defined annotation handle.
	ANNHANDLETYPE_ROTATE_HANDLE	A rotate annotation handle
nID	Unique identifier of the annotation handle. If ‘nType’ is ANNHANDLETYPE_ROTATE_HANDLE, then nID specifies if this is a center rotate handle (ROTATE_HANDLE_CENTER_ID) or a gripper rotate handle (ROTATE_HANDLE_GRIPPER_ID)
nIndex	This is the index of the user handle of the privately maintained array of user handles. Use nIndex with L_AnnChangeUserHandle or L_AnnDeleteUserHandle. This is only valid if the type of the handle is ANNHANDLETYPE_DEFAULT_HANDLE.
ptLocationContainer	The location of the handle in container coordinates. Container coordinates are typically the same dimensions of the underlying bitmap, and are independent of zooming and scrolling.
ptLocationClient	The location of the handle in client coordinates. Client coordinates factor in the current zoom factor, and the horizontal and vertical scrolling.

bVisible	Value that indicates whether the handle is visible. Possible values are:
	Value	Meaning
	TRUE	The handle is visible.
	FALSE	The handle is invisible.
crPen	A COLORREF value that represents the color of the pen used to draw the user handle (the outline of the handle).
crFill	A COLORREF value that represents the color used to fill the user handle.

nShape	A value that indicates the shape of the handle. Possible values are:
	Value	Meaning
	ANNHANDLE_SHAPE_SQUARE	The shape of the user handle is square
	ANNHANDLE_SHAPE_CIRCLE	The shape of the user handle is a circle
hCursor	Handle to a cursor. This is the cursor that appears when the mouse hovers over the user handle. If this value is zero, then a default cursor will appear.
nTotalHandles	The total number of annotation object handles. This includes both the default annotation handles and the user-defined annotation handles.
nReserved	Reserved for future use. Must set this field to zero.
