| Method Summary | |
| public void | copyArea(int x, int y, int width, int height, int dx, int dy)
Copies an area of the component by a distance specified by
dx and dy. | | public Graphics | create()
Creates a new Graphics object that is
a copy of this Graphics object. | | 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. | | public void | draw(Shape s)
Strokes the outline of a Shape using the settings of the
current Graphics2D context. | | public boolean | drawImage(Image img, int x, 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
(x, y) in this graphics context's coordinate
space. | | public boolean | drawImage(Image img, int x, int y, 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. | | public void | drawRenderableImage(RenderableImage img, AffineTransform xform)
Renders a
RenderableImage ,
applying a transform from image space into user space before drawing.
The transformation from user space into device space is done with
the current Transform in the Graphics2D.
The specified transformation is applied to the image before the
transform attribute in the Graphics2D context is applied.
The rendering attributes applied include the Clip,
Transform, and Composite attributes. | | public void | drawRenderedImage(RenderedImage img, AffineTransform xform)
Renders a
RenderedImage ,
applying a transform from image
space into user space before drawing.
The transformation from user space into device space is done with
the current Transform in the Graphics2D.
The specified transformation is applied to the image before the
transform attribute in the Graphics2D context is applied.
The rendering attributes applied include the Clip,
Transform, and Composite attributes. | | public void | drawString(String s, float x, float y)
Renders the text specified by the specified String,
using the current Font and Paint attributes
in the Graphics2D context.
The baseline of the first character is at position
(x, y) in the User Space.
The rendering attributes applied include the Clip,
Transform, Paint, Font and
Composite attributes. | | public void | drawString(AttributedCharacterIterator iterator, float x, float y)
Renders the text of the specified iterator, using the
Graphics2D context's current Paint. | | public void | fill(Shape s)
Fills the interior of a Shape using the settings of the
Graphics2D context. | | public GraphicsConfiguration | getDeviceConfiguration()
Returns the device configuration associated with this
Graphics2D. | | public FontMetrics | getFontMetrics(Font f)
Gets the font metrics for the specified font. | | public void | setXORMode(Color c1)
Sets the paint mode of this graphics context to alternate between
this graphics context's current color and the new specified color. |
| DefaultGraphics2D | | public DefaultGraphics2D(boolean textAsShapes)(Code) | | Default constructor
|
| copyArea | | public void copyArea(int x, int y, int width, int height, int dx, int dy)(Code) | | Copies an area of the component by a distance specified by
dx and dy. 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.
Parameters:
x - the x coordinate of the source rectangle.
Parameters:
y - the y coordinate of the source rectangle.
Parameters:
width - the width of the source rectangle.
Parameters:
height - the height of the source rectangle.
Parameters:
dx - the horizontal distance to copy the pixels.
Parameters:
dy - the vertical distance to copy the pixels. |
| create | | public Graphics create()(Code) | | Creates a new Graphics object that is
a copy of this Graphics object.
a new graphics context that is a copy ofthis graphics context. |
| dispose | | public void dispose()(Code) | | 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.

| drawImage | | public boolean drawImage(Image img, int x, int y, ImageObserver observer)(Code) | | Draws as much of the specified image as is currently available.
The image is drawn with its top-left corner at
(x, y) 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.
Parameters:
x - the x coordinate.
Parameters:
y - the y coordinate.
Parameters:
observer - object to be notified as more ofthe image is converted.

| drawImage | | public boolean drawImage(Image img, int x, int y, int width, int height, ImageObserver observer)(Code) | | 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.
Parameters:
x - the x coordinate.
Parameters:
y - the y coordinate.
Parameters:
width - the width of the rectangle.
Parameters:
height - the height of the rectangle.
Parameters:
observer - object to be notified as more ofthe image is converted.

| drawRenderableImage | | public void drawRenderableImage(RenderableImage img, AffineTransform xform)(Code) | | Renders a
RenderableImage ,
applying a transform from image space into user space before drawing.
The transformation from user space into device space is done with
the current Transform in the Graphics2D.
The specified transformation is applied to the image before the
transform attribute in the Graphics2D context is applied.
The rendering attributes applied include the Clip,
Transform, and Composite attributes. Note
that no rendering is done if the specified transform is
noninvertible.
Rendering hints set on the Graphics2D object might
be used in rendering the RenderableImage.
If explicit control is required over specific hints recognized by a
specific RenderableImage, or if knowledge of which hints
are used is required, then a RenderedImage should be
obtained directly from the RenderableImage
and rendered using
DefaultGraphics2D.drawRenderedImage(RenderedImage,AffineTransform) drawRenderedImage .
Parameters:
img - the image to be rendered
Parameters:
xform - the transformation from image space into user space

| drawRenderedImage | | public void drawRenderedImage(RenderedImage img, AffineTransform xform)(Code) | | Renders a
RenderedImage ,
applying a transform from image
space into user space before drawing.
The transformation from user space into device space is done with
the current Transform in the Graphics2D.
The specified transformation is applied to the image before the
transform attribute in the Graphics2D context is applied.
The rendering attributes applied include the Clip,
Transform, and Composite attributes. Note
that no rendering is done if the specified transform is
noninvertible.
Parameters:
img - the image to be rendered
Parameters:
xform - the transformation from image space into user space

| getDeviceConfiguration | | public GraphicsConfiguration getDeviceConfiguration()(Code) | | Returns the device configuration associated with this
Graphics2D.
|
| setXORMode | | public void setXORMode(Color c1)(Code) | | Sets the paint mode of this graphics context to alternate between
this graphics context's current color and the new specified color.
This specifies that logical pixel operations are performed in the
XOR mode, which alternates pixels between the current color and
a specified XOR color.
When drawing operations are performed, pixels which are the
current color are changed to the specified color, and vice versa.
Pixels that are of colors other than those two colors are changed
in an unpredictable but reversible manner; if the same figure is
drawn twice, then all pixels are restored to their original values.
Parameters:
c1 - the XOR alternation color |
