L_BOOL bVisible;

flag that indicates whether the container will be visible

Creates and initializes an annotation object that is a container.

Parameter Description
hWnd Handle to the window for the container.
pRect Pointer to the LEADTOOLS ANNRECT structure that specifies the container. The ANNRECT structure is like a Windows RECT structure, except that it uses double-precision floating point values.
  Coordinates of an object's rectangle are relative to its container object. The coordinates are interpreted using the container's scaling factors and offsets, which are described in Low-Level Coordinate System for Annotations.
bVisible Flag that indicates whether the container will be visible. Possible values are:
  Value Meaning
  TRUE The container is visible.
  FALSE The container is not visible.

Returns
