public class WarpFilter extends WholeImageFilter
A filter for warping images using the gridwarp algorithm. You need to supply two warp grids, one for the source image and one for the destination image. The image will be warped so that a point in the source grid moves to its counterpart in the destination grid.

  • Constructor Details

    • WarpFilter

      public WarpFilter()
      Create a WarpFilter.

    • WarpFilter

      public WarpFilter(WarpGrid sourceGrid, WarpGrid destGrid)
      Create a WarpFilter with two warp grids.
      Parameters:
      sourceGrid - the source grid
      destGrid - the destination grid

  • Method Details

    • setSourceGrid

      public void setSourceGrid(WarpGrid sourceGrid)
      Set the source warp grid.
      Parameters:
      sourceGrid - the source grid
      See Also:

    • getSourceGrid

      public WarpGrid getSourceGrid()
      Get the source warp grid.
      Returns:
      the source grid

    • setDestGrid

      public void setDestGrid(WarpGrid destGrid)
      Set the destination warp grid.
      Parameters:
      destGrid - the destination grid
      See Also:

    • getDestGrid

      public WarpGrid getDestGrid()
      Get the destination warp grid.
      Returns:
      the destination grid

    • getFrames

      public int getFrames()

    • setMorphImage

      public void setMorphImage(BufferedImage morphImage)
      For morphing, sets the image we're morphing to. If not, set then we're just warping.

      Description copied from class: WholeImageFilter
      Calculate output bounds for given input bounds.
      Overrides:
      transformSpace in class WholeImageFilter
