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

filter

                   BufferedImage dst)

指定者:

filter 在接口中 BufferedImageOp

覆盖:

filter 在类中 TransformFilter

toString

public String toString()

覆盖:

toString 在类中 Object
