                  String movieType)

Method Detail

addImageAsFrame

public void addImageAsFrame(BufferedImage image)
                     throws IOException

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

Parameters:

image - the image to add as a frame

Throws:

IOException - if there is an error while adding the frame

addImageAsFrame

public void addImageAsFrame(BufferedImage image,
                            int sleepCount)
                     throws IOException

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

Throws:

IOException - if there is an error while adding the frame
