is transformed with the current Graphics2D
Transform

.
This method is used to make the current Clip
smaller. To make the
Clip
larger, use setClip
. The user clip modified by
this method is independent of the clipping associated with device bounds and
visibility. If no clip has previously been set, or if the clip has been cleared
using setClip
with a null
argument, the
specified Shape
becomes the new user clip.

encapsulates
application hints such as anti-aliasing and fractional metrics, as well as target
device specific information such as dots-per-inch. This information should be
provided by the application when using objects that perform typographical formatting,
such as Font
and TextLayout
. This information should also
be provided by applications that perform their own layout and need accurate
measurements of various characteristics of glyphs such as advance and line height
when various rendering hints have been applied to the text rendering.

. From the point specified by x
and y
, this
method copies downwards and to the right. To copy an area of the component to the
left or upwards, specify a negative value for dx
or dy
. If
a portion of the source rectangle lies outside the bounds of the component, or is
obscured by another window or component, copyArea
will be unable to copy
the associated pixels. The area that is omitted can be refreshed by calling the
component's paint
method.

Graphics
object cannot be used after dispose
has 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.
