Examples of com.lightcrafts.model.Contour

com.lightcrafts.model.Contour
Regions define masks for image processing Operations. A Contour is a connected component of a Region. Regions are unions of Contours.
Contours are immutable and safe for concurrent access, except for the getTranslation() accessor which may update to indicate the special case change of getting translated.
