      • maxFrames

        public static int maxFrames(int width,            int height,            boolean color)
        Attempts to determine how many filmstrip frames an still be created with a specified size. This is not necessarily going to give an exact value; the value is likely to be an underestimate.
        Parameters:
        width - the width in pixels of the images
        height - the height in pixels of the images
        color - are the images to be colored (4 bytes per pixel) or black and white (1 byte per pixel)?

      • setFrame

        public void setFrame(int frameNumber,            BufferedImage image)
        Sets a specified frame in the filmstrip to a given image. If frameNumber is less than the current filmstrip size, then the current frame at position frameNumber is replaced. Otherwise the size of the filmstrip is increased to (frameNumber+1) and the image is then stored in position frameNumber as the last frame in the filmstrip. Any extra locations that are created are filled with nulls.
        Parameters:
        frameNumber - The position in the filmstrip where the image is to be added. An error occurs if this is less than zero.
        image - The image that is to be put at postion frameNumber in the filmstrip. This can be null.
      • getFrameCount

        public int getFrameCount()
        Returns the current number of frames in the filmstrip.
      • getFrame

        public BufferedImage getFrame(int frameNumber)
        Returns the image at at a specified position in the filmstrip. The return value can be null.
        Parameters:
        frameNumber - The number of the frame that is to be returned. An error occurs if this is not greater than or equal to zero and less than getFrameCount().
      • stripNullFrames

        public void stripNullFrames()
        Removes any frames for which the image is null from the filmstrip.
