Class WarpFilter

Implemented Interfaces:
BufferedImageOp, Cloneable
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.

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

crossDissolve

public void crossDissolve(int[] pixels1,
                          int[] pixels2,
                          int width,
                          int height,
                          float t)

filterPixels

protected int[] filterPixels(int width,
                             int height,
                             int[] inPixels,
                             Rectangle transformedSpace)
Overrides:
filterPixels in interface WholeImageFilter

getDestGrid

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

getFrames

public int getFrames()

getMorphImage

public BufferedImage getMorphImage()

getSourceGrid

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

getTime

public float getTime()

morph

public void morph(int[] srcPixels,
                  int[] destPixels,
                  int[] outPixels,
                  WarpGrid srcGrid,
                  WarpGrid destGrid,

destGrid - the destination grid
See Also:
getDestGrid()

setFrames

public void setFrames(int frames)

setMorphImage

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

setSourceGrid

Parameters:
sourceGrid - the source grid
See Also:
getSourceGrid()

setTime

public void setTime(float time)

toString

public String toString()
