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.

构造器详细资料

WarpFilter

public WarpFilter()

Create a WarpFilter.

WarpFilter

public WarpFilter(WarpGrid sourceGrid,
          WarpGrid destGrid)

Create a WarpFilter with two warp grids.

参数:

sourceGrid - the source grid

destGrid - the destination grid

方法详细资料

setSourceGrid

public void setSourceGrid(WarpGrid sourceGrid)

Set the source warp grid.

参数:

sourceGrid - the source grid

另请参阅:

getSourceGrid()

getSourceGrid

public WarpGrid getSourceGrid()

Get the source warp grid.

返回:

the source grid

另请参阅:

setSourceGrid(cn.apiclub.captcha.filter.image.WarpGrid)

setDestGrid

public void setDestGrid(WarpGrid destGrid)

Set the destination warp grid.

参数:

destGrid - the destination grid

另请参阅:

getDestGrid()

getDestGrid

public WarpGrid getDestGrid()

Get the destination warp grid.

返回:

the destination grid

另请参阅:

setDestGrid(cn.apiclub.captcha.filter.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)

从类复制的说明: WholeImageFilter

Calculate output bounds for given input bounds.

覆盖:

transformSpace 在类中 WholeImageFilter

参数:

r - input and output rectangle

filterPixels

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

从类复制的说明: WholeImageFilter

Actually filter the pixels.

指定者:

filterPixels 在类中 WholeImageFilter

参数:

width - the image width

height - the image height

inPixels - the image pixels

transformedSpace - the output bounds

返回:

the output pixels

morph

public void morph(int[] srcPixels,
         int[] destPixels,

                 int height,
                 float t)

toString

public String toString()

覆盖:

toString 在类中 Object
