    • getBounds2D

      public Rectangle2D getBounds2D()
      Description copied from interface: Filter
      Returns the bounds of the current image. This should be 'in sync' with getMinX, getMinY, getWidth, getHeight
      Specified by:
      getBounds2D in interface Filter
      Overrides:
      getBounds2D in class AbstractRable
    • getSource

      public Filter getSource()
      Returns the source to be affine.
      Specified by:
      getSource in interface AffineRable
    • setSource

      public void setSource(Filter src)
      Sets the source to be affine.
      Specified by:
      setSource in interface AffineRable
      Parameters:
      src - image to affine.
    • setAffine

      public void setAffine(AffineTransform affine)
      Set the affine transform.
      Specified by:
      setAffine in interface AffineRable
      Parameters:
      affine - the new Affine transform to apply.
    • getAffine

      public AffineTransform getAffine()
      Get the Affine.
      Specified by:
      getAffine in interface AffineRable
      Returns:
      the Affine transform currently in effect.
    • paintRable

      public boolean paintRable(Graphics2D g2d)
      Should perform the equivilent action as createRendering followed by drawing the RenderedImage.
      Specified by:
      paintRable in interface PaintRable
      Parameters:
      g2d - The Graphics2D to draw to.
      Returns:
      true if the paint call succeeded, false if for some reason the paint failed (in which case a createRendering should be used).
    • createRendering

      public RenderedImage createRendering(RenderContext rc)
      Specified by:
      createRendering in interface RenderableImage
    • getDependencyRegion

      public Shape getDependencyRegion(int srcIndex, Rectangle2D outputRgn)
      Description copied from interface: Filter
      Returns the region of input data is is required to generate outputRgn.
      Specified by:
      getDependencyRegion in interface Filter
      Overrides:
      getDependencyRegion in class AbstractRable
      Parameters:
      srcIndex - The source to do the dependency calculation for.
      outputRgn - The region of output you are interested in generating dependencies for. The is given in the user coordiate system for this node.
      Returns:
      The region of input required. This is in the user coordinate system for the source indicated by srcIndex.
    • getDirtyRegion

      public Shape getDirtyRegion(int srcIndex, Rectangle2D inputRgn)
      Description copied from interface: Filter
      This calculates the region of output that is affected by a change in a region of input.
      Specified by:
      getDirtyRegion in interface Filter
      Overrides:
      getDirtyRegion in class AbstractRable
      Parameters:
      srcIndex - The input that inputRgn reflects changes in.
      inputRgn - the region of input that has changed, used to calculate the returned shape. This is given in the user coordinate system of the source indicated by srcIndex.
      Returns:
      The region of output that would be invalid given a change to inputRgn of the source selected by srcIndex. this is in the user coordinate system of this node.
