Object	clone()
protected void	dieOnCircularReference()	Convenience method.
protected void	dieOnCircularReference(Stack<Object> stack, Project project)	Check to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).
protected void	dieOnCircularReference(Project p)	Convenience method.

static void	invokeCircularReferenceCheck(DataType dt, Stack<Object> stk, Project p)	Allow DataTypes outside org.apache.tools.ant.types to indirectly call dieOnCircularReference on nested DataTypes.
protected boolean	isChecked()	The flag that is used to indicate that circular references have been checked.
boolean	isReference()	Has the refid attribute of this element been set?

Field Details

angle

protected float angle

Constructor Details

Rotate

public Rotate()

Method Details

setAngle

public void setAngle(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)

Rotate an image.

Parameters:

image - the image to rotate.

Returns:

the rotated 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.

Returns:

the transformed image.

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

Returns:

the image.
