Method Detail

addRenderingHints

public void addRenderingHints(Map hints)

Sets the values of an arbitrary number of preferences for the rendering algorithms. Only values for the rendering hints that are present in the specified Map object are modified. All other preferences not present in the specified object are left unmodified. Hint categories include controls for rendering quality and overall time/quality trade-off in the rendering process. Refer to the RenderingHints class for definitions of some common keys and values.

Parameters:: hints - - the rendering hints to be set

clearRect

public void clearRect(int x,
                      int y,
                      int width,
                      int height)

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.

Parameters:: 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.
See Also:: Graphics.fillRect(int, int, int, int), Graphics.drawRect(int, int, int, int), Graphics.setColor(java.awt.Color), Graphics.setPaintMode(), Graphics.setXORMode(java.awt.Color)

clip

public void clip(Shape clipShape)

Intersects the current Clip with the interior of the specified Shape and sets the Clip to the resulting intersection. The specified Shape is transformed with the current Graphics2D Transform before being intersected with the current Clip. 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.

Parameters:: clipShape - - the Shape to be intersected with the current Clip. If s is null, this method clears the current Clip.

clipRect

public void clipRect(int x,
                     int y,
                     int width,
                     int height)

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.

Parameters:: 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; height - the height of the rectangle to intersect the clip with
See Also:: setClip(int, int, int, int), setClip(Shape)

copyArea

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. 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.; y - the y coordinate of the source rectangle.; width - the width of the source rectangle.; height - the height of the source rectangle.; dx - the horizontal distance to copy the pixels.; dy - the vertical distance to copy the pixels.

create

public Graphics create()

Creates a new Graphics object that is a copy of this Graphics object.

Returns:: a new graphics context that is a copy of this graphics context.

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.

See Also:: Graphics.finalize(), Component.paint(java.awt.Graphics), Component.update(java.awt.Graphics), Component.getGraphics(), Graphics.create()

draw

public void draw(Shape shape)

Strokes the outline of a Shape using the settings of the current Graphics2D context. The rendering attributes applied include the Clip, Transform, Paint, Composite and Stroke attributes.

Parameters:: shape - - the Shape to be rendered

drawArc

public void drawArc(int x,
                    int y,
                    int width,
                    int height,
                    int startAngle,
                    int arcAngle)

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.

Parameters:: 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.; height - the height of the arc to be drawn.; startAngle - the beginning angle.; arcAngle - the angular extent of the arc, relative to the start angle.
See Also:: Graphics.fillArc(int, int, int, int, int, int)

drawGlyphVector

public void drawGlyphVector(GlyphVector glyph,
                            float x,
                            float y)

Renders the text of the specified GlyphVector using the Graphics2D context's rendering attributes. The rendering attributes applied include the Clip, Transform, Paint, and Composite attributes. The GlyphVector specifies individual glyphs from a Font. The GlyphVector can also contain the glyph positions. This is the fastest way to render a set of characters to the screen.

Parameters:: glyph - - the GlyphVector to be rendered; x - - the horizontal position in User Space where the glyphs should be rendered; y - - the vertical position in User Space where the glyphs should be rendered

drawImage

public void drawImage(BufferedImage image,
                      BufferedImageOp imageOp,
                      int x,
                      int y)

Renders a BufferedImage that is filtered with a BufferedImageOp. The rendering attributes applied include the Clip, Transform and Composite attributes.

Parameters:: image - - the BufferedImage to be rendered; imageOp - - the filter to be applied to the image before rendering; x - - the horizontal location in user space where the upper left corner of the image is rendered; y - - the vertical location in user space where the upper left corner of the image is rendered

drawImage

public boolean drawImage(Image image,
                         AffineTransform transform,
                         ImageObserver obs)

Renders an image, 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:: image - - the Image to be rendered; transform - - the transformation from image space into user space; obs - - the ImageObserver to be notified as more of the Image is converted
Returns:: boolean

drawImage

public boolean drawImage(Image img,
                         int x,
                         int y,
                         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 (x, y) 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.
Returns:: true if the image is completely loaded; false otherwise.

drawImage

public boolean drawImage(Image img,
                         int x,
                         int y,
                         ImageObserver observer)

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.
Returns:: true if the image is completely loaded; false otherwise.

drawImage

public boolean drawImage(Image img,
                         int x,
                         int y,
                         int width,
                         int height,
                         Color bgcolor,
                         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 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.

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.; 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.
Returns:: true if the current output representation is complete; false otherwise.

drawImage

public boolean drawImage(Image img,
                         int dx1,
                         int dy1,
                         int dx2,
                         int dy2,
                         int sx1,
                         int sy1,
                         int sx2,
                         int sy2,
                         Color bgcolor,
                         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 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 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.; sx2 - the x coordinate of the second corner of the source rectangle.; sy2 - the y coordinate of the second corner of the source rectangle.; 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 scaled and converted.

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.

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.
