                         int height,
                         double frameRate)

Default constructor that takes the frame size and frame rate of the resulting video.

Parameters:

filename - The filename to write the video to

width - The width of the video frame in pixels

height - The height of the video frame in pixels

frameRate - The frame rate of the resulting video

Method Detail

initialise

public void initialise()
