Constructor Detail

Rotate

public Rotate()

Method Detail

setAngle

public void setAngle(java.lang.String ang)

Sets the angle of rotation in degrees.

Parameters:

ang - The angle at which to rotate the image

performRotate

public java.awt.image.BufferedImage performRotate(java.awt.image.BufferedImage image)

Rotate an image.

Parameters:

image - the image to rotate.

Returns:

the rotated image.

executeTransformOperation

public java.awt.image.BufferedImage executeTransformOperation(java.awt.image.BufferedImage image)

Performs the image rotation when being handled as a TransformOperation.

Specified by:

executeTransformOperation in class TransformOperation

Parameters:

image - The image to perform the transformation on.

Returns:

the transformed image.

executeDrawOperation

public java.awt.image.BufferedImage executeDrawOperation()

Performs the image rotation when being handled as a DrawOperation. It absolutely requires that there be a DrawOperation nested beneath it, but only the FIRST DrawOperation will be handled since it can only return ONE image.

Specified by:

executeDrawOperation in interface DrawOperation

Returns:

the image.
