构造器详细资料

RotateFilter

public RotateFilter()

Construct a RotateFilter.

RotateFilter

public RotateFilter(float angle)

Construct a RotateFilter.

参数:

angle - the angle to rotate

RotateFilter

public RotateFilter(float angle,
                    boolean resize)

Construct a RotateFilter.

参数:

angle - the angle to rotate

resize - true if the output image should be resized

方法详细资料

setAngle

public void setAngle(float angle)

Specifies the angle of rotation.

参数:

angle - the angle of rotation.

另请参阅:

getAngle()

getAngle

public float getAngle()

Returns the angle of rotation.

返回:

the angle of rotation.

另请参阅:

setAngle(float)

transformSpace

protected void transformSpace(Rectangle rect)

从类复制的说明: TransformFilter

Forward transform a rectangle. Used to determine the size of the output image.

覆盖:

transformSpace 在类中 TransformFilter

参数:

rect - the rectangle to transform

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 String toString()

覆盖:

toString 在类中 Object
