public class ImageDisplay
- extends ImageDisplay
Display an image on the screen using the ptolemy.media.Picture
class. For a sequence of images that are all the same size, this
class will continually update the picture with new data. If the
size of the input image changes, then a new Picture object is
created. This class will only accept a IntMatrixToken on its
input, and assumes that the input image contains greyscale pixel
intensities between 0 and 255 (inclusive). The token is
read in postfire().
Note that this actor really should be replaced by a conversion
actor that converts IntMatrixTokens to ImageTokens. However,
there is no easy way to do that without accessing the graphical
context of the actor. An alternative would be to use the
Java Advanced Imaging package and create an actor like
$PTII/ptolemy/actor/lib/jai/DoubleMatrixToJAI.java.

public ImageDisplay(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.
