ISvgNodeRenderer implementation for the tag.
  • Field Details

    • points

      protected List<Point> points
      A List of Point objects representing the path to be drawn by the polyline tag
  • Constructor Details

    • PolylineSvgNodeRenderer

      public PolylineSvgNodeRenderer()
  • Method Details

    • getPoints

      protected List<Point> getPoints()
    • setPoints

      protected void setPoints (String pointsAttribute)
      Parses a string of space separated x,y pairs into individual Point objects and appends them topoints. Throws an SvgProcessingException if pointsAttribute does not have a valid list of numerical x,y pairs.
      pointsAttribute - A string of space separated x,y value pairs
    • getObjectBoundingBox

      public Rectangle getObjectBoundingBox (SvgDrawContext context)
      Description copied from interface: ISvgNodeRenderer
      Calculates the current object bounding box.
      Specified by:
      getObjectBoundingBox in interface ISvgNodeRenderer
      context - the current context, for instance it contains current viewport and available font data
      the Rectangle representing the current object's bounding box, or null if bounding box is undefined
    • doDraw

      protected void doDraw (SvgDrawContext context)
      Draws this element to a canvas-like object maintained in the context.
      Specified by:
      doDraw in class AbstractSvgNodeRenderer
      context - the object that knows the place to draw this element and maintains its state
    • createDeepCopy

      public ISvgNodeRenderer createDeepCopy()
      Description copied from interface: ISvgNodeRenderer
      Creates a deep copy of this renderer, including it's subtree of children
      Specified by:
      createDeepCopy in interface ISvgNodeRenderer
      deep copy of this renderer
    • drawMarker

      public void drawMarker (SvgDrawContext context, MarkerVertexType markerVertexType)
      Description copied from interface: IMarkerCapable
      Draws a marker in the specified context. The marker is drawn on the vertices defined according to the given marker type.
      Specified by:
      drawMarker in interface IMarkerCapable
      context - the object that knows the place to draw this element and maintains its state
      markerVertexType - type of marker that determine on which vertices of the given element marker should be drawn
    • getAutoOrientAngle

      public double getAutoOrientAngle (MarkerSvgNodeRenderer marker, boolean reverse)
      Description copied from interface: IMarkerCapable
      Calculates marker orientation angle if orient attribute is set to auto
      Specified by:
      getAutoOrientAngle in interface IMarkerCapable
      marker - marker for which the rotation angle should be calculated
      reverse - indicates that the resulting angle should be rotated 180 degrees
      marker orientation angle so that its positive x-axis is pointing in the direction of the path at the point it is placed
