  - clip
```
@NotImplemented
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.
    
    Specified by:
    
    clip in class java.awt.Graphics2D
    
    Parameters:
    
    s - the Shape to be intersected with the current Clip. If s is null, this method clears the current Clip.
  - getClip
```
@NotImplemented
public java.awt.Shape getClip()
```
    Gets the current clipping area. This method returns 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.
    
    Specified by:

                    int arcAngle)
```
    Fills a circular or elliptical arc covering the specified rectangle.
    The resulting arc begins at startAngle and extends for arcAngle degrees. 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.

    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.

```
    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.

```
    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.

  - 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.

    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.

```
    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.

@NotImplemented
public void setClip(java.awt.Shape clip)
```
    Sets the current clipping area to an arbitrary clip shape. Not all objects that implement the Shape interface can be used to set the clip. The only Shape objects that are guaranteed to be supported are Shape objects that are obtained via the getClip method and via Rectangle objects. This method sets the user clip, which is independent of the clipping associated with device bounds and window visibility.
    
    Specified by:
    
    setClip in class java.awt.Graphics
    
    Parameters:
    
    clip - the Shape to use to set the clip

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.
    
    Specified by:
    
    getClipBounds in class java.awt.Graphics
    
    Returns:
    
    the bounding rectangle of the current clipping area, or null if no clip is set.

  - rotate
```
public void rotate(double theta)
```
    Concatenates the current Graphics2D Transform with a rotation transform. Subsequent rendering is rotated by the specified radians relative to the previous origin. This is equivalent to calling transform(R), where R is an AffineTransform represented by the following matrix:
```
          [   cos(theta)    -sin(theta)    0   ]
          [   sin(theta)     cos(theta)    0   ]
          [       0              0         1   ]
 
```
    Rotating with a positive angle theta rotates points on the positive x axis toward the positive y axis.

    Parameters:
    
    theta - the angle of rotation in radians
  - rotate
```
public void rotate(double theta,
                   double x,
                   double y)
```
    Concatenates the current Graphics2D Transform with a translated rotation transform. 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);
 
```
    Rotating with a positive angle theta rotates points on the positive x axis toward the positive y axis.
    Specified by:
    
    rotate in class java.awt.Graphics2D
    
    Parameters:
    
    theta - the angle of rotation in radians
    
    x - x coordinate of the origin of the rotation
    
    y - y coordinate of the origin of the rotation
  - shear
```
public void shear(double shx,
                  double shy)
```
    Concatenates the current Graphics2D Transform with a shearing transform. Subsequent renderings are sheared by the specified multiplier relative to the previous position. This is equivalent to calling transform(SH), where SH is an AffineTransform represented by the following matrix:
```
          [   1   shx   0   ]
          [  shy   1    0   ]
          [   0    0    1   ]

    shx - the multiplier by which coordinates are shifted in the positive X axis direction as a function of their Y coordinate
    
    shy - the multiplier by which coordinates are shifted in the positive Y axis direction as a function of their X coordinate
  - 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.
    
    Specified by:
    
    getFontRenderContext in class java.awt.Graphics2D
    
    Returns:
    
    a reference to an instance of FontRenderContext.

  - transform
```
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.
    
    Specified by:
    
    transform in class java.awt.Graphics2D
    
    Parameters:
    
    Tx - the AffineTransform object to be composed with the current Transform

                      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:

  - 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.
    
    Specified by:
    
    setBackground in class java.awt.Graphics2D
    
    Parameters:
    
    color - the background color that isused in subsequent calls to clearRect

  - setComposite
```
@NotImplemented
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.
    
    Specified by:
    
    setComposite in class java.awt.Graphics2D
    
    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.

```
    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 loads 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.
    
    Specified by:
    
    drawImage in class java.awt.Graphics
    
    Parameters:
    
    img - the specified image to be drawn. This method does nothing if img is null.
    
    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.
    
    Returns:
    
    false if the image pixels are still changing; true otherwise.

  - create
```
public java.awt.Graphics create()
```
    Creates a new Graphics object that is a copy of this Graphics object.
    
    Specified by:
    
    create in class java.awt.Graphics
    
    Returns:
    
    a new graphics context that is a copy of this graphics context.
  - getFontMetrics
```
public java.awt.FontMetrics getFontMetrics(java.awt.Font f)
```
    Gets the font metrics for the specified font.
    
    Specified by:
    
    getFontMetrics in class java.awt.Graphics
    
    Parameters:
    
    f - the specified font
    
    Returns:
    
    the font metrics for the specified font.
    
    See Also:
    
    Graphics.getFont(), FontMetrics, Graphics.getFontMetrics()
  - setXORMode
```
@NotImplemented
public void setXORMode(java.awt.Color c1)
```
    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.
    
    Specified by:
    
    setXORMode in class java.awt.Graphics
    
    Parameters:
    
    c1 - the XOR alternation color
  - setPaintMode
```
@NotImplemented
public void setPaintMode()
```
    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.
    
    Specified by:
    
    setPaintMode in class java.awt.Graphics
  - drawRenderedImage
```
@NotImplemented
public void drawRenderedImage(java.awt.image.RenderedImage img,
                                              java.awt.geom.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. 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 drawRenderedImage.
    
    Specified by:
    
    drawRenderedImage in class java.awt.Graphics2D
    
    Parameters:
    
    img - the image to be rendered. This method does nothing if img is null.
    
    xform - the transformation from image space into user space

    _transform, setTransform(java.awt.geom.AffineTransform), setComposite(java.awt.Composite), clip(java.awt.Shape), setClip(java.awt.Shape), drawRenderedImage(java.awt.image.RenderedImage, java.awt.geom.AffineTransform)
