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 javax.media.jai.PlanarImage performRotate(javax.media.jai.PlanarImage image)

executeTransformOperation

public javax.media.jai.PlanarImage executeTransformOperation(javax.media.jai.PlanarImage 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.

executeDrawOperation

public javax.media.jai.PlanarImage 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
