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 Detail

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 Detail

setSourceGrid

public void setSourceGrid(WarpGrid sourceGrid)

Set the source warp grid.

Parameters:

sourceGrid - the source grid

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

getDestGrid

public WarpGrid getDestGrid()

Get the destination warp grid.

Returns:

the destination grid

setFrames

public void setFrames(int frames)

getFrames

public int getFrames()

setMorphImage

public void setMorphImage(java.awt.image.BufferedImage morphImage)

For morphing, sets the image we're morphing to. If not, set then we're just warping.

getMorphImage

public java.awt.image.BufferedImage getMorphImage()

setTime

public void setTime(float time)

getTime

public float getTime()

transformSpace

protected void transformSpace(java.awt.Rectangle r)

Overrides:
