                    int startAngle,
                    int arcAngle)
Fills a circular or elliptical arc covering the specified rectangle.

The resulting arc begins at startAngle and extends for arcAngle degrees. Angles are interpreted such that 0 degrees is at the 3 o'clock position. A positive value indicates a counter-clockwise rotation while a negative value indicates a clockwise rotation.

The center of the arc is the center of the rectangle whose origin is (xy) and whose size is specified by the width and height arguments.

The resulting arc covers an area width + 1 pixels wide by height + 1 pixels tall.

Parameters:
x - the x coordinate of the upper-left corner of the arc to be filled.
y - the y coordinate of the upper-left corner of the arc to be filled.
width - the width of the arc to be filled.
height - the height of the arc to be filled.
startAngle - the beginning angle.
arcAngle - the angular extent of the arc, relative to the start angle.

                         int y,
                         ImageObserver observer)
Draws as much of the specified image as is currently available. The image is drawn with its top-left corner at (xy) in this graphics context's coordinate space. Transparent pixels in the image do not affect whatever pixels are already there.

This method returns immediately in all cases, even if the complete image has not yet been loaded, and it has not been dithered and converted for the current output device.

If the image has not yet been completely loaded, then drawImage returns false. As more of the image becomes available, the process that draws the image notifies the specified image observer.

Parameters:
img - the specified image to be drawn.
x - the x coordinate.
y - the y coordinate.
observer - object to be notified as more of the image is converted.
Overrides:

                         int width,
                         int height,
                         ImageObserver observer)
Draws as much of the specified image as has already been scaled to fit inside the specified rectangle.

The image is drawn inside the specified rectangle of this graphics context's coordinate space, and is scaled if necessary. Transparent pixels do not affect whatever pixels are already there.

This method returns immediately in all cases, even if the entire image has not yet been scaled, dithered, and converted for the current output device. If the current output representation is not yet complete, then drawImage returns false. As more of the image becomes available, the process that draws the image notifies the image observer by calling its imageUpdate method.

A scaled version of an image will not necessarily be available immediately just because an unscaled version of the image has been constructed for this output device. Each size of the image may be cached separately and generated from the original data in a separate image production sequence.

Parameters:
img - the specified image to be drawn.
x - the x coordinate.
y - the y coordinate.
width - the width of the rectangle.
height - the height of the rectangle.
observer - object to be notified as more of the image is converted.

                         Color bgcolor,
                         ImageObserver observer)
Draws as much of the specified image as is currently available. The image is drawn with its top-left corner at (xy) in this graphics context's coordinate space. Transparent pixels are drawn in the specified background color.

This operation is equivalent to filling a rectangle of the width and height of the specified image with the given color and then drawing the image on top of it, but possibly more efficient.

This method returns immediately in all cases, even if the complete image has not yet been loaded, and it has not been dithered and converted for the current output device.

If the image has not yet been completely loaded, then drawImage returns false. As more of the image becomes available, the process that draws the image notifies the specified image observer.

Parameters:
img - the specified image to be drawn.
x - the x coordinate.
y - the y coordinate.
bgcolor - the background color to paint under the non-opaque portions of the image.
observer - object to be notified as more of the image is converted.

                         int sy2,
                         ImageObserver observer)
Draws as much of the specified area of the specified image as is currently available, scaling it on the fly to fit inside the specified area of the destination drawable surface. Transparent pixels do not affect whatever pixels are already there.

This method returns immediately in all cases, even if the image area to be drawn has not yet been scaled, dithered, and converted for the current output device. If the current output representation is not yet complete then drawImage returns false. As more of the image becomes available, the process that draws the image notifies the specified image observer.

This method always uses the unscaled version of the image to render the scaled rectangle and performs the required scaling on the fly. It does not use a cached, scaled version of the image for this operation. Scaling of the image from source to destination is performed such that the first coordinate of the source rectangle is mapped to the first coordinate of the destination rectangle, and the second source coordinate is mapped to the second destination coordinate. The subimage is scaled and flipped as needed to preserve those mappings.

Parameters:
img - the specified image to be drawn
dx1 - the x coordinate of the first corner of the destination rectangle.
dy1 - the y coordinate of the first corner of the destination rectangle.
dx2 - the x coordinate of the second corner of the destination rectangle.
dy2 - the y coordinate of the second corner of the destination rectangle.
sx1 - the x coordinate of the first corner of the source rectangle.
sy1 - the y coordinate of the first corner of the source rectangle.

dispose

public void dispose()
Disposes of this graphics context and releases any system resources that it is using. A Graphics object cannot be used after disposehas been called.

When a Java program runs, a large number of Graphics objects can be created within a short time frame. Although the finalization process of the garbage collector also disposes of the same system resources, it is preferable to manually free the associated resources by calling this method rather than to rely on a finalization process which may not run to completion for a long period of time.

Graphics objects which are provided as arguments to the paint and update methods of components are automatically released by the system when those methods return. For efficiency, programmers should call dispose when finished using a Graphics object only if it was created directly from a component or another Graphics object.

transform

public void transform(AffineTransform Tx)
Composes a Transform object with the transform in this Graphics2D according to the rule last-specified-first-applied. If the currrent transform is Cx, the result of composition with Tx is a new transform Cx'. Cx' becomes the current transform for this Graphics2D. Transforming a point p by the updated transform Cx' is equivalent to first transforming p by Tx and then transforming the result by the original transform Cx. In other words, Cx'(p) = Cx(Tx(p)). A copy of the Tx is made, if necessary, so further modifications to Tx do not affect rendering.
