DisplaceFilter

public DisplaceFilter()

方法详细资料

setDisplacementMap

public void setDisplacementMap(java.awt.image.BufferedImage displacementMap)

Set the displacement map.

参数:

displacementMap - an image representing the displacment at each point

另请参阅:

getDisplacementMap()

getDisplacementMap

public java.awt.image.BufferedImage getDisplacementMap()

Get the displacement map.

返回:

an image representing the displacment at each point

另请参阅:

setDisplacementMap(java.awt.image.BufferedImage)

setAmount

public void setAmount(float amount)

Set the amount of distortion.

参数:

amount - the amount min-value 0 max-value 1

另请参阅:

getAmount

public float getAmount()

Get the amount of distortion.

返回:

the amount

另请参阅:

setAmount(float)

filter

public java.awt.image.BufferedImage filter(java.awt.image.BufferedImage src,
                                           java.awt.image.BufferedImage dst)

指定者:

filter 在接口中 java.awt.image.BufferedImageOp

覆盖:

filter 在类中 TransformFilter

transformInverse

protected void transformInverse(int x,
                                int y,
                                float[] out)

从类复制的说明: TransformFilter

Inverse transform a point. This method needs to be overriden by all subclasses.

指定者:

transformInverse 在类中 TransformFilter

参数:

x - the X position of the pixel in the output image

y - the Y position of the pixel in the output image

out - the position of the pixel in the input image

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object
