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

See Also:

getSourceGrid()

getSourceGrid

public WarpGrid getSourceGrid()

Get the source warp grid.

Returns:

the source grid

See Also:

setSourceGrid(org.zimowski.bambi.jhlabs.image.WarpGrid)

setDestGrid

public void setDestGrid(WarpGrid destGrid)

Set the destination warp grid.

Parameters:

destGrid - the destination grid

See Also:

getDestGrid()

getDestGrid

public WarpGrid getDestGrid()

Get the destination warp grid.

Returns:

the destination grid

See Also:

setDestGrid(org.zimowski.bambi.jhlabs.image.WarpGrid)

setFrames

public void setFrames(int frames)

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.

getMorphImage

public BufferedImage getMorphImage()

setTime

public void setTime(float time)

getTime

public float getTime()

transformSpace

protected void transformSpace(Rectangle r)

Description copied from class: WholeImageFilter

Calculate output bounds for given input bounds.

Overrides:

transformSpace in class WholeImageFilter

Parameters:

r - input and output rectangle

filterPixels

protected int[] filterPixels(int width,
                 int height,
                 int[] inPixels,
                 Rectangle transformedSpace)

Description copied from class: WholeImageFilter

Actually filter the pixels.

Specified by:

filterPixels in class WholeImageFilter

Parameters:

width - the image width

height - the image height

inPixels - the image pixels

transformedSpace - the output bounds

Returns:

the output pixels

morph
