java.lang.Object org.gvsig.fmap.geom.primitive.GeneralPathX
public class GeneralPathX
The GeneralPathX
class represents a geometric path
constructed from straight lines, and quadratic and cubic
(Bézier) curves. It can contain multiple subpaths.
The winding rule specifies how the interior of a path is determined. There are two types of winding rules: EVEN_ODD and NON_ZERO.
An EVEN_ODD winding rule means that enclosed regions of the path alternate between interior and exterior areas as traversed from the outside of the path towards a point inside the region.
A NON_ZERO winding rule means that if a ray is drawn in any direction from a given point to infinity and the places where the path intersects the ray are examined, the point is inside of the path if and only if the number of times that the path crosses the ray from left to right does not equal the number of times that the path crosses the ray from right to left.

to the path, possibly connecting the new geometry to the existing
path segments with a line segment.
If the connect
parameter is true
and the
path is not empty then any initial moveTo
in the
geometry of the appended Shape
is turned into a
lineTo
segment.
If the destination coordinates of such a connecting lineTo
segment match the ending coordinates of a currently open
subpath then the segment is omitted as superfluous.
The winding rule of the specified Shape
is ignored
and the appended geometry is governed by the winding
rule specified for this path.
