Constructor Detail

AnimatedGifCreator

public AnimatedGifCreator(java.awt.image.BufferedImage aIm,
                          java.lang.String aFileName,
                          java.lang.String aComments,
                          int aUniformDelay,
                          int aLoopCount)

Constructs a new AnimatedGifCreator. After you have constructed it, you can draw into the Graphics2D returned by drawingGraphics() to draw into the image held in this object. After you've completed a frame, call updateComplete(). If you are using this object in multiple threads, synchronize access to it, while drawing into the Graphics2D returned by drawingGraphics. After using this object, you should call its dispose() method to write the file.

Method Detail

drawingGraphics

public java.awt.Graphics2D drawingGraphics()

Returns a Graphics2D object that can be used to draw into the BufferedImage.

Specified by:

drawingGraphics in interface AnimationListener

updateComplete

public void updateComplete()

Should be called when frame complete, adds it to Gif89Encoder. This method is synchronized to prevent other threads from changing the BufferedImage in the mean time.

Specified by:

updateComplete in interface AnimationListener

isWorking

public boolean isWorking()

Whether this AnimationListener is ready to be sent image information (or whether it is useful to do so. For example, a window, after being made invisible does not need any more graphics information.) Returns false after dispose() has been called.

Specified by:

isWorking in interface AnimationListener

dispose

public void dispose()

Encodes into a file.

Specified by:

dispose in interface AnimationListener
