All Implemented Interfaces:

javax.media.ControllerListener, javax.media.datasink.DataSinkListener

public class MovieMaker

extends Object

implements javax.media.ControllerListener, javax.media.datasink.DataSinkListener

Takes DisplaySurface images and makes movies out of them. All messages sent to this class should be done through DisplaySurface.

Constructor Detail

MovieMaker

public MovieMaker(int width,
                  int height,
                  int frameRate,
                  String fileName,
                  String movieType)

Method Detail

init

public boolean init(javax.media.format.RGBFormat format)

addImageAsFrame

public void addImageAsFrame(Image image)

Adds an image to a movie as a frame with a default sleep value of 40

Parameters:

image - the image to add as a frame

addImageAsFrame

public void addImageAsFrame(Image image,
                            int sleepCount)

Adds an image to a movie as a frame. This method pause the main simulation thread for the specified amount of time. This pause is necessary to allow the images to be written to disk in a background thread. Without the pauses the images are still written to disk, but are added much faster than they can be written, resulting in increased memory use and eventual OutOfMemoryErrors. This method is called by DisplaySurface and shouldn't be called by a user in the course of writing a model.

Parameters:

image - the image to add as a frame

sleepCount - the amount to pause for writing images to disk
