Constructor Detail

ColorFinder

public ColorFinder(CompositeEntity container,
                   java.lang.String name)
            throws IllegalActionException,
                   NameDuplicationException

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

fire

public void fire()
          throws IllegalActionException

Fire this actor. Output the X and Y coordinates if it finds the color in the Buffer.

Specified by:

fire in interface Executable

Overrides:

fire in class AtomicActor

Throws:

IllegalActionException - If a contained method throws it, or if a token is received that contains a null image.

initialize

public void initialize()
                throws IllegalActionException

Initialize this actor. Set the color to search for in the YUV domain.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class AtomicActor

Throws:

IllegalActionException - If a contained method throws it.

_getVComponent

private int _getVComponent(int point)

Return the int representing the V band at this pixel

_getVComponent

private int _getVComponent(int x,
                           int y)
