Sets a region that will define the clipping region for the object
 o setDisplayBounds(QDRect)
QTCanvas calls this method when it needs to tell the client to adjust its location, width and/or height.
 o setGraphicsMode(GraphicsMode)
Determines the graphics mode for an image.
 o setGWorld(QDGraphics)
QTCanvas calls this method to give the client the QDGraphics object it should use to do its drawing.

A convenience method to set the position of a QTDrawable object.
 o setMatrix(Matrix)
This method sets the current matrix of the Transformable object to the new matrix.
 o toString()
Returns a String representation of this object.

Constructors

 o GraphicsImporterDrawer
 public GraphicsImporterDrawer(GraphicsImporter gi)
This constructor creates an GraphicsImporterDrawer object from an existing GraphicsImporter.

Parameters:
gi - the GraphicsImporter
 o GraphicsImporterDrawer
 public GraphicsImporterDrawer(QTFile file) throws QTException
This constructor creates an GraphicsImporterDrawer object from a file.

Parameters:
file - the QTFile.
 o GraphicsImporterDrawer
 public GraphicsImporterDrawer(DataRef dataRef) throws QTException
This constructor creates an GraphicsImporterDrawer object from a data ref.

Parameters:
dataRef - the dataRef that contains the locations of the image data.

Methods

 o getImporter
 public GraphicsImporter getImporter()
This returns the GraphicsImporter object that is responsible for importing and drawing the picture file.

 o getClip
 public Region getClip() throws QTException
Returns a region that defines the current clipping region for the object.

Returns:
the clipping region
 o setClip
 public void setClip(Region reg) throws StdQTException
Sets a region that will define the clipping region for the object

Parameters:
reg - the new clipping region
 o getDescription
 public ImageDescription getDescription() throws StdQTException
This method should return an ImageDescription that describes the image data that the class contains.

Returns:
the ImageDescription of an Image
 o getImage
 public EncodedImage getImage() throws QTException
This method returns the actual image data of the GraphicsImporterDrawer's GraphicImporter. An Exception is throw if there was some problem retrieving the data.

Returns:
the image data
 o addedTo
 public void addedTo(Object interest)
This method is called by the specified object when the instance of the class that implements this interface is added to the object that is the source of the interest.

Parameters:
interest - the object that is to be the source of interest for the the object that implements this interface.
 o removedFrom
 public void removedFrom(Object interest)
This method is called by the specified object when the instance of the class that implements this interface is removed from the object that is the source of the interest.

Parameters:
interest - the object that was the source of interest for the the object that implements this interface.
 o getGWorld
 public QDGraphics getGWorld() throws StdQTException
QTCanvas calls this method to get the destination QDGraphics of its client.

Returns:
a QDGraphics object or null
 o setGWorld
 public void setGWorld(QDGraphics cgp) throws StdQTException
QTCanvas calls this method to give the client the QDGraphics object it should use to do its drawing. If the incoming QDGraphics is the QDGraphics.scratch then the drawable will not be visible and can disable itself. If a client is unable to set the graphics world it should throw an exception.

Parameters:
cgp - a QDGraphics object
 o getInitialSize
 public Dimension getInitialSize() throws QTException
This method returns the original size before the transformations specified in the returned matrix are applied.

 o getMatrix
 public Matrix getMatrix() throws StdQTException
This will return the client's current display transformations

Returns:
the display transformations of the client
 o setMatrix
 public void setMatrix(Matrix matrix) throws QTException
This method sets the current matrix of the Transformable object to the new matrix.

 o setDisplayBounds
 public void setDisplayBounds(QDRect bounds) throws StdQTException
QTCanvas calls this method when it needs to tell the client to adjust its location, width and/or height. All values are in pixels.

Parameters:
bounds - the new size and location.
 o setLocation
 public void setLocation(int x,
                         int y) throws QTException
A convenience method to set the position of a QTDrawable object.

Parameters:
x - the new x location
y - the new y location
 o getDisplayBounds
 public QDRect getDisplayBounds() throws StdQTException
QTCanvas calls this method when it needs to ask the client for its boundary. All values are in pixels.

Returns:
the boundary of the client
 o redraw
 public final synchronized void redraw(Region invalidRgn) throws QTException
QTCanvas calls this method when the client should redraw itself. If the canvas is able to discern that only a part of the client's drawing area needs to be redrawn - then this area shall be passed in using the invalidRgn. Otherwise this will be null in which case the client should redraw itself entirely.

Parameters:
invalidRgn - the invalidRgn that the client should redraw
 o getGraphicsMode
 public GraphicsMode getGraphicsMode() throws StdQTException
Determines the graphics mode for an image.

Returns:
The graphics transfer mode.

Determines the graphics mode for an image.

Returns:
The graphics transfer mode.
 o toString
 public String toString()
Returns a String representation of this object.

Overrides:
toString in class Object
