Clears the specified rectangle by filling it with the background color of the current drawing surface. This operation does not use the current paint mode.
Beginning with Java 1.1, the background color
of offscreen images may be system dependent. Applications should
use setColor
followed by fillRect
to
ensure that an offscreen image is cleared to a specific color.
x | the x coordinate of the rectangle to clear. |
---|---|
y | the y coordinate of the rectangle to clear. |
width | the width of the rectangle to clear. |
height | the height of the rectangle to clear. |
Intersects the current clip with the specified rectangle.
The resulting clipping area is the intersection of the current
clipping area and the specified rectangle. If there is no
current clipping area, either because the clip has never been
set, or the clip has been cleared using setClip(null)
,
the specified rectangle becomes the new clip.
This method sets the user clip, which is independent of the
clipping associated with device bounds and window visibility.
This method can only be used to make the current clip smaller.
To set the current clip larger, use any of the setClip methods.
Rendering operations have no effect outside of the clipping area.
x | the x coordinate of the rectangle to intersect the clip with |
---|---|
y | the y coordinate of the rectangle to intersect the clip with |
width | the width of the rectangle to intersect the clip with |

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.
x | the x coordinate of the source rectangle. |
---|---|
y | the y coordinate of the source rectangle. |
width | the width of the source rectangle. |

Creates a new Graphics
object based on this
Graphics
object, but with a new translation and clip area.
The new Graphics
object has its origin
translated to the specified point (x, y).
Its clip area is determined by the intersection of the original
clip area with the specified rectangle. The arguments are all
interpreted in the coordinate system of the original
Graphics
object. The new graphics context is
identical to the original, except in two respects:
0
, 0
) in the
new graphics context is the same as (x, y) in
the original graphics context.
0
, 0
), and its size
is specified by the width
and height
arguments.
x | the x coordinate. |
---|---|
y | the y coordinate. |
width | the width of the clipping rectangle. |
height | the height of the clipping rectangle. |
Creates a new Graphics
object that is
a copy of this Graphics
object.
Disposes of this graphics context and releases
any system resources that it is using.
A 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.
Draws a 3-D highlighted outline of the specified rectangle. The edges of the rectangle are highlighted so that they appear to be beveled and lit from the upper left corner.
The colors used for the highlighting effect are determined
based on the current color.
The resulting rectangle covers an area that is
width + 1
pixels wide
by height + 1
pixels tall.
x | the x coordinate of the rectangle to be drawn. |
---|---|
y | the y coordinate of the rectangle to be drawn. |
width | the width of the rectangle to be drawn. |
height | the height of the rectangle to be drawn. |
raised | a boolean that determines whether the rectangle appears to be raised above the surface or sunk into the surface. |
Draws the outline of a circular or elliptical arc covering the specified rectangle.
The resulting arc begins at startAngle
and extends
for arcAngle
degrees, using the current color.
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 (x, y) 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.
The angles are specified relative to the non-square extents of the bounding rectangle such that 45 degrees always falls on the line from the center of the ellipse to the upper right corner of the bounding rectangle. As a result, if the bounding rectangle is noticeably longer in one axis than the other, the angles to the start and end of the arc segment will be skewed farther along the longer axis of the bounds.
x | the x coordinate of the upper-left corner of the arc to be drawn. |
---|---|
y | the y coordinate of the upper-left corner of the arc to be drawn. |
width | the width of the arc to be drawn. |

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 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
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 specified image observer.
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.

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.

height | the height of the new clip rectangle. |
Sets this graphics context's current color to the specified color. All subsequent graphics operations using this graphics context use this specified color.
c | the new rendering color. |

Sets this graphics context's font to the specified font. All subsequent text operations using this graphics context use this font.
font | the font. |

Sets the paint mode of this graphics context to overwrite the destination with this graphics context's current color. This sets the logical pixel operation function to the paint or overwrite mode. All subsequent rendering operations will overwrite the destination with the current color.
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.
c1 | the XOR alternation color |

Translates the origin of the graphics context to the point (x, y) in the current coordinate system. Modifies this graphics context so that its new origin corresponds to the point (x, y) in this graphics context's original coordinate system. All coordinates used in subsequent rendering operations on this graphics context will be relative to this new origin.
x | the x coordinate. |
