public abstract class AbstractGraphics2D
extends java.awt.Graphics2D
implements java.lang.Cloneable

This extension of the `java.awt.Graphics2D` abstract class is still abstract, but it implements a lot of the `Graphics2D` method in a way that concrete implementations can reuse. This class uses a `GraphicContext` to store the state of its various attributes that control the rendering, such as the current `Font`, `Paint` or clip. Concrete implementations can focus on implementing the rendering methods, such as `drawShape`. As a convenience, rendering methods that can be expressed with other rendering methods (e.g., `drawRect` can be expressed as `draw(new Rectangle(..))`), are implemented by `AbstractGraphics2D`

### getClipBounds

    public java.awt.Rectangle getClipBounds()

  Returns the bounding rectangle of the current clipping area. This method refers to the user clip, which is independent of the clipping associated with device bounds and window visibility. If no clip has previously been set, or if the clip has been cleared using `setClip(null)`, this method returns `null`. The coordinates in the rectangle are relative to the coordinate system origin of this graphics context.

  Returns:
    the bounding rectangle of the current clipping area, or `null` if no clip is set.
  Since:
    JDK1.1
  See Also:
    `Graphics.getClip()`, `Graphics.clipRect(int, int, int, int)`, `Graphics.setClip(int, int, int, int)`, `Graphics.setClip(Shape)`

### clipRect

                         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

  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.

  Parameters:
    `xPoints` - an array of x points
    `yPoints` - an array of y points
    `nPoints` - the total number of points

### drawPolygon

    public void drawPolygon(int[] xPoints,
                            int[] yPoints,
                            int nPoints)

  Draws a closed polygon defined by arrays of x and y coordinates. Each pair of (x, y) coordinates defines a point.

  This method draws the polygon defined by `nPoint` line segments, where the first `nPoint - 1` line segments are line segments from `(xPoints[i - 1], yPoints[i - 1])` to `(xPoints[i], yPoints[i])`, for 1 ≤ i ≤ `nPoints`. The figure is automatically closed by drawing a line connecting the final point to the first point, if those points are different.

  Parameters:
    `xPoints` - a an array of `x` coordinates.
    `yPoints` - a an array of `y` coordinates.
    `nPoints` - a the total number of points.

  Fills a closed polygon defined by arrays of x and y coordinates.

  This method draws the polygon defined by `nPoint` line segments, where the first `nPoint - 1` line segments are line segments from `(xPoints[i - 1], yPoints[i - 1])` to `(xPoints[i], yPoints[i])`, for 1 ≤ i ≤ `nPoints`. The figure is automatically closed by drawing a line connecting the final point to the first point, if those points are different.

  The area inside the polygon is defined using an even-odd fill rule, also known as the alternating rule.

  Parameters:
    `xPoints` - a an array of `x` coordinates.
    `yPoints` - a an array of `y` coordinates.
    `nPoints` - a the total number of points.

### drawImage

    public boolean drawImage(java.awt.Image img,
                             int x,
                             int y,
                             java.awt.Color bgcolor,
                             java.awt.image.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.

                             java.awt.image.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.

                             java.awt.image.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.
    `sx2` - the x coordinate of the second corner of the source rectangle.
    `sy2` - the y coordinate of the second corner of the source rectangle.
    `observer` - object to be notified as more of the image is scaled and converted.

                             java.awt.image.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:
    `img` - the `Image` to be rendered
    `xform` - the transformation from image space into user space
    `obs` - the `ImageObserver` to be notified as more of the `Image` is converted
  Returns:
    `true` if the `Image` is fully loaded and completely rendered; `false` if the `Image` is still being loaded.

                          int y)

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

       img1 = op.filter(img, null);
       drawImage(img1, new AffineTransform(1f,0f,0f,1f,x,y), null);

  Parameters:
    `op` - the filter to be applied to the image before rendering
    `img` - the `BufferedImage` to be rendered

                       java.awt.Shape s,
                       boolean onStroke)

  Checks whether or not the specified `Shape` intersects the specified `Rectangle`, which is in device space. If `onStroke` is false, this method checks whether or not the interior of the specified `Shape` intersects the specified `Rectangle`. If `onStroke` is `true`, this method checks whether or not the `Stroke` of the specified `Shape` outline intersects the specified `Rectangle`. The rendering attributes taken into account include the `Clip`, `Transform`, and `Stroke` attributes.

  Parameters:
    `rect` - the area in device space to check for a hit
    `s` - the `Shape` to check for a hit
    `onStroke` - flag used to choose between testing the stroked or the filled shape. If the flag is `true`, the `Stroke` oultine is tested. If the flag is `false`, the filled `Shape` is tested.
  Returns:
    `true` if there is a hit; `false` otherwise.

### setComposite

    public void setComposite(java.awt.Composite comp)

  Sets the `Composite` for the `Graphics2D` context. The `Composite` is used in all drawing methods such as `drawImage`, `drawString`, `draw`, and `fill`. It specifies how new pixels are to be combined with the existing pixels on the graphics device during the rendering process.

  If this `Graphics2D` context is drawing to a `Component` on the display screen and the `Composite` is a custom object rather than an instance of the `AlphaComposite` class, and if there is a security manager, its `checkPermission` method is called with an `AWTPermission("readDisplayPixels")` permission.

  Parameters:
    `comp` - the `Composite` object to be used for rendering
  Throws:
    `java.lang.SecurityException` - if a custom `Composite` object is being used to render to the screen and a security manager is set and its `checkPermission` method does not allow the operation.

### setPaint

    public void setPaint(java.awt.Paint paint)

  Sets the `Paint` attribute for the `Graphics2D` context. Calling this method with a `null` `Paint` object does not have any effect on the current `Paint` attribute of this `Graphics2D`.

  Parameters:
    `paint` - the `Paint` object to be used to generate color during the rendering process, or `null`

Subsequent rendering is transformed by a transform which is constructed by translating to the specified location, rotating by the specified radians, and translating back by the same amount as the original translation. This is equivalent to the following sequence of calls:

                translate(x, y);
                rotate(theta);
                translate(-x, -y);

    public void transform(java.awt.geom.AffineTransform Tx)

  Composes an `AffineTransform` object with the `Transform` in this `Graphics2D` according to the rule last-specified-first-applied. If the current `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.

  Parameters:
    `Tx` - the `AffineTransform` object to be composed with the current `Transform`
  See Also:
    `setTransform(java.awt.geom.AffineTransform)`, `AffineTransform`

### setTransform

    public void setTransform(java.awt.geom.AffineTransform Tx)

  Sets the `Transform` in the `Graphics2D` context.

  Parameters:
    `Tx` - the `AffineTransform` object to be used in the rendering process
  See Also:
    `transform(java.awt.geom.AffineTransform)`, `AffineTransform`

### getTransform

    public java.awt.geom.AffineTransform getTransform()

  Returns a copy of the current `Transform` in the `Graphics2D` context.

  Returns:
    the current `AffineTransform` in the `Graphics2D` context.
  See Also:
    `transform(java.awt.geom.AffineTransform)`, `setTransform(java.awt.geom.AffineTransform)`

### getPaint

    public java.awt.Paint getPaint()

  Returns the current `Paint` of the `Graphics2D` context.

  Returns:
    the current `Graphics2D` `Paint`, which defines a color or pattern.
  See Also:
    `setPaint(java.awt.Paint)`, `Graphics.setColor(java.awt.Color)`

### getComposite

    public java.awt.Composite getComposite()

  Returns the current `Composite` in the `Graphics2D` context.

  Returns:
    the current `Graphics2D` `Composite`, which defines a compositing style.
  See Also:
    `setComposite(java.awt.Composite)`

### setBackground

    public void setBackground(java.awt.Color color)

  Sets the background color for the `Graphics2D` context. The background color is used for clearing a region. When a `Graphics2D` is constructed for a `Component`, the background color is inherited from the `Component`. Setting the background color in the `Graphics2D` context only affects the subsequent `clearRect` calls and not the background color of the `Component`. To change the background of the `Component`, use appropriate methods of the `Component`.

  Parameters:
    `color` - the background color that isused in subsequent calls to `clearRect`
  See Also:
    `getBackground()`, `Graphics.clearRect(int, int, int, int)`

### getBackground

    public java.awt.Color getBackground()

  Returns the background color used for clearing a region.

  Returns:
    the current `Graphics2D` `Color`, which defines the background color.
  See Also:
    `setBackground(java.awt.Color)`

### getStroke

    public java.awt.Stroke getStroke()

  Returns the current `Stroke` in the `Graphics2D` context.

  Returns:
    the current `Graphics2D` `Stroke`, which defines the line style.
  See Also:
    `setStroke(java.awt.Stroke)`

### clip

    public void clip(java.awt.Shape s)

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

### getFontRenderContext

    public java.awt.font.FontRenderContext getFontRenderContext()

  Get the rendering context of the `Font` within this `Graphics2D` context. The `FontRenderContext` 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.

  Returns:
    a reference to an instance of FontRenderContext.
  Since:
    JDK1.2
  See Also:
    `FontRenderContext`, `Font.createGlyphVector(java.awt.font.FontRenderContext, java.lang.String)`, `TextLayout`
