  • Apparatus and method of generating curved baseline for map labeling
    Patent number: 7692655
    Abstract: Apparatus and methods of generating a curved baseline for a map labeling include receiving a polyline P={p1,p2, . . . ,pn} of n points, generating a supporting polyline Q={q1,q2, . . . , qm} (m?n) of m points at an expected distance d between polyline P and a curved base line L. A predetermined number of B-Spline points is generated based upon supporting polyline Q. The B-Spline points are then connected to form a curved baseline L for displaying a label.
