Contour2D::isValidRegion Method

Syntax

C++

bool isValidRegion(const OdGeTol& gTol = FMGeGbl::gTol) const;

Parameters	Description
const OdGeTol& gTol = FMGeGbl::gTol	[in] Tolerance.

false for empty and non-closed contours.
false if there are coincident bounds with opposite directions (e.g., O-O shape).
false if there are sub-contours with incorrect orientation (e.g., 8 shape).
true otherwise.

Checks whether this contour is closed and coincides with a directional boundary of an open 2D region.
