    • Method Summary

      Modifier and Type Method and Description
      void closePath()
      Closes the current subpath by drawing a straight line back to the coordinates of the last moveTo.
      void curveTo(float cx1, float cy1, float cx2, float cy2, float x, float y)
      Adds a curved segment, defined by three new points, to the path by drawing a Bezier curve that intersects both the current coordinates and the coordinates (x3, y3), using the specified points (x1, y1) and (x2, y2) as Bezier control points.
      void flush()
      This guarantees that this writer has flushed all currently written information.
      void lineTo(float x, float y)
      Adds a point to the path by drawing a straight line from the current coordinates to the new specified coordinates.
      void moveTo(float x, float y)
      Adds a point to the path by moving to the specified coordinates.
      void quadTo(float cx, float cy, float x, float y)
      Adds a curved segment, defined by two new points, to the path by drawing a Quadratic curve that intersects both the current coordinates and the coordinates (x2, y2), using the specified point (x1, y1) as a quadratic parametric control point.

      • closePath

        public void closePath()
        Description copied from class: PathWriter
        Closes the current subpath by drawing a straight line back to the coordinates of the last moveTo.

      • flush

        public void flush()
        Description copied from class: PathWriter
        This guarantees that this writer has flushed all currently written information.

        For example, some writers may need to perform complex calculations and re-organize shapes. Or some writers may simply be buffering path instructions to better manage memory. Calling this method guarantees that all path instructions be immediately processed.

        Because some writers may be manipulating path data you should not call this method until all shape data has been written.
