◆ SetBaseSurface() [1/2]

bool ON_OffsetSurface::SetBaseSurface ( const ON_Surface * base_surface )

Description: Sets base surface to a surface that is not managed by the ON_OffsetSurface class. Parameters: base_surface - [in] points to a base surface the caller insures will exist for the lifetimes of the ON_OffsetSurface class. Returns: True if successful.

◆ SetBaseSurface() [2/2]

bool ON_OffsetSurface::SetBaseSurface	(	ON_Surface *	base_surface,

Description: Sets base surface to a surface that is optionally managed by the ON_OffsetSurface class. Parameters: base_surface - [in] points to a base surface the caller insures will exist for the lifetimes of the ON_OffsetSurface class. bManage - [in] if true, the base_surface must point to a surface that is on the heap and the surface will be deleted by ~ON_OffsetSurface. Returns: True if successful.
