Class PolylineShapeIterator

  • All Implemented Interfaces:
    java.awt.geom.PathIterator
    public class PolylineShapeIterator
extends java.lang.Object
implements java.awt.geom.PathIterator
    PathIterator for PolylineShape. This class was originally written by wil - amristar.com.au and integrated into iText by Bruno.

    • Method Detail

      • currentSegment

        public int currentSegment​(double[] coords)
        Returns the coordinates and type of the current path segment in the iteration. The return value is the path segment type: SEG_MOVETO, SEG_LINETO, SEG_QUADTO, SEG_CUBICTO, or SEG_CLOSE. A double array of length 6 must be passed in and may be used to store the coordinates of the point(s). Each point is stored as a pair of double x,y coordinates. SEG_MOVETO and SEG_LINETO types will return one point, SEG_QUADTO will return two points, SEG_CUBICTO will return 3 points and SEG_CLOSE will not return any points.

        currentSegment in interface java.awt.geom.PathIterator

      • currentSegment

        public int currentSegment​(float[] coords)
