  • Field Summary

    Fields
    Modifier and Type
    Field
    Description
    static final int
    FILL_EVEN_ODD
    The fill rule constant for specifying an even-odd rule for determining the interior of a path.
    The even-odd rule specifies that a point lies inside the path if a ray drawn in any direction from that point to infinity is crossed by path segments an odd number of times.
    static final int
    FILL_NON_ZERO
    The fill rule constant for specifying a non-zero rule for determining the interior of a path.
    The non-zero rule specifies that a point lies inside the path if a ray drawn in any direction from that point to infinity is crossed by path segments a different number of times in the counter-clockwise direction than the clockwise direction.
    static final int
    VERB_CLOSE
    Primitive commands of path segments.
    static final int
    VERB_CUBIC
    Primitive commands of path segments.
    static final int
    VERB_DONE
    Primitive commands of path segments.
    static final int
    VERB_LINE
    Primitive commands of path segments.
    static final int
    VERB_MOVE
    Primitive commands of path segments.
    static final int
    VERB_QUAD
    Primitive commands of path segments.

    • getFillRule

      int getFillRule()
      Returns the filling rule for determining the interior of the path.
      Returns:
      the winding rule.

    • next

      int next(float[] coords, int offset)
      Returns next verb, and advances iterator. If there are no more elements, returns VERB_DONE.

      Zero to three points are stored in coords, depending on the command type.

      A float array of length >= 6 must be passed in and can be used to store the coordinates of the point(s). Each point is stored as a pair of float x,y coordinates.

      • MOVE returns 1 point
      • LINE returns 1 point
      • QUAD returns 2 points
      • CUBIC returns 3 points
      • CLOSE does not return any points
      Parameters:
      coords - array for point data describing returned verb, can be null
      Returns:
      next verb
