Class Graphics2D

  • java.lang.Object
    • java.awt.Graphics
      • java.awt.Graphics2D
  • public abstract class Graphics2D extends Graphics
    This Graphics2D class extends the Graphics class to provide more sophisticated control over geometry, coordinate transformations, color management, and text layout. This is the fundamental class for rendering 2-dimensional shapes, text and images on the Java(tm) platform.

    Coordinate Spaces

    All coordinates passed to a Graphics2D object are specified in a device-independent coordinate system called User Space, which is used by applications. The Graphics2D object contains an AffineTransform object as part of its rendering state that defines how to convert coordinates from user space to device-dependent coordinates in Device Space.

    Coordinates in device space usually refer to individual device pixels and are aligned on the infinitely thin gaps between these pixels. Some Graphics2D objects can be used to capture rendering operations for storage into a graphics metafile for playback on a concrete device of unknown physical resolution at a later time. Since the resolution might not be known when the rendering operations are captured, the Graphics2D Transform is set up to transform user coordinates to a virtual device space that approximates the expected resolution of the target device. Further transformations might need to be applied at playback time if the estimate is incorrect.

    Some of the operations performed by the rendering attribute objects occur in the device space, but all Graphics2D methods take user space coordinates.

    Every Graphics2D object is associated with a target that defines where rendering takes place. A GraphicsConfiguration object defines the characteristics of the rendering target, such as pixel format and resolution. The same rendering target is used throughout the life of a Graphics2D object.

    When creating a Graphics2D object, the GraphicsConfiguration specifies the default transform for the target of the Graphics2D (a Component or Image). This default transform maps the user space coordinate system to screen and printer device coordinates such that the origin maps to the upper left hand corner of the target region of the device with increasing X coordinates extending to the right and increasing Y coordinates extending downward. The scaling of the default transform is set to identity for those devices that are close to 72 dpi, such as screen devices. The scaling of the default transform is set to approximately 72 user space coordinates per square inch for high resolution devices, such as printers. For image buffers, the default transform is the Identity transform.

    Rendering Process

    The Rendering Process can be broken down into four phases that are controlled by the Graphics2D rendering attributes. The renderer can optimize many of these steps, either by caching the results for future calls, by collapsing multiple virtual steps into a single operation, or by recognizing various attributes as common simple cases that can be eliminated by modifying other parts of the operation.

    The steps in the rendering process are:

    1. Determine what to render.
    2. Constrain the rendering operation to the current Clip. The Clip is specified by a Shape in user space and is controlled by the program using the various clip manipulation methods of Graphics and Graphics2D. This user clip is transformed into device space by the current Transform and combined with the device clip, which is defined by the visibility of windows and device extents. The combination of the user clip and device clip defines the composite clip, which determines the final clipping region. The user clip is not modified by the rendering system to reflect the resulting composite clip.
    3. Determine what colors to render.
    4. Apply the colors to the destination drawing surface using the current Composite attribute in the Graphics2D context.

    The three types of rendering operations, along with details of each of their particular rendering processes are:
    1. Shape operations
      1. If the operation is a draw(Shape) operation, then the createStrokedShape method on the current Stroke attribute in the Graphics2D context is used to construct a new Shape object that contains the outline of the specified Shape.
      2. The Shape is transformed from user space to device space using the current Transform in the Graphics2D context.
      3. The outline of the Shape is extracted using the getPathIterator method of Shape, which returns a PathIterator object that iterates along the boundary of the Shape.
      4. If the Graphics2D object cannot handle the curved segments that the PathIterator object returns then it can call the alternate getPathIterator method of Shape, which flattens the Shape.
      5. The current Paint in the Graphics2D context is queried for a PaintContext, which specifies the colors to render in device space.
    2. Text operations
      1. The following steps are used to determine the set of glyphs required to render the indicated String:
        1. If the argument is a String, then the current Font in the Graphics2D context is asked to convert the Unicode characters in the String into a set of glyphs for presentation with whatever basic layout and shaping algorithms the font implements.
        2. If the argument is an AttributedCharacterIterator, the iterator is asked to convert itself to a TextLayout using its embedded font attributes. The TextLayout implements more sophisticated glyph layout algorithms that perform Unicode bi-directional layout adjustments automatically for multiple fonts of differing writing directions.
        3. If the argument is a GlyphVector, then the GlyphVector object already contains the appropriate font-specific glyph codes with explicit coordinates for the position of each glyph.
      2. The current Font is queried to obtain outlines for the indicated glyphs. These outlines are treated as shapes in user space relative to the position of each glyph that was determined in step 1.
      3. The character outlines are filled as indicated above under Shape operations.
      4. The current Paint is queried for a PaintContext, which specifies the colors to render in device space.
    3. Image Operations
      1. The region of interest is defined by the bounding box of the source Image. This bounding box is specified in Image Space, which is the Image object's local coordinate system.
      2. If an AffineTransform is passed to drawImage(Image, AffineTransform, ImageObserver), the AffineTransform is used to transform the bounding box from image space to user space. If no AffineTransform is supplied, the bounding box is treated as if it is already in user space.
      3. The bounding box of the source Image is transformed from user space into device space using the current Transform. Note that the result of transforming the bounding box does not necessarily result in a rectangular region in device space.
      4. The Image object determines what colors to render, sampled according to the source to destination coordinate mapping specified by the current Transform and the optional image transform.

    Default Rendering Attributes

    The default values for the Graphics2D rendering attributes are:
    Paint
    The color of the Component.
    Font
    The Font of the Component.
    Stroke
    A square pen with a linewidth of 1, no dashing, miter segment joins and square end caps.
    Transform
    The getDefaultTransform for the GraphicsConfiguration of the Component.
    Composite
    The AlphaComposite.SRC_OVER rule.
    Clip
    No rendering Clip, the output is clipped to the Component.

    Rendering Compatibility Issues

    The JDK(tm) 1.1 rendering model is based on a pixelization model that specifies that coordinates are infinitely thin, lying between the pixels. Drawing operations are performed using a one-pixel wide pen that fills the pixel below and to the right of the anchor point on the path. The JDK 1.1 rendering model is consistent with the capabilities of most of the existing class of platform renderers that need to resolve integer coordinates to a discrete pen that must fall completely on a specified number of pixels.

    The Java 2D(tm) (Java(tm) 2 platform) API supports antialiasing renderers. A pen with a width of one pixel does not need to fall completely on pixel N as opposed to pixel N+1. The pen can fall partially on both pixels. It is not necessary to choose a bias direction for a wide pen since the blending that occurs along the pen traversal edges makes the sub-pixel position of the pen visible to the user. On the other hand, when antialiasing is turned off by setting the KEY_ANTIALIASING hint key to the VALUE_ANTIALIAS_OFF hint value, the renderer might need to apply a bias to determine which pixel to modify when the pen is straddling a pixel boundary, such as when it is drawn along an integer coordinate in device space. While the capabilities of an antialiasing renderer make it no longer necessary for the rendering model to specify a bias for the pen, it is desirable for the antialiasing and non-antialiasing renderers to perform similarly for the common cases of drawing one-pixel wide horizontal and vertical lines on the screen. To ensure that turning on antialiasing by setting the KEY_ANTIALIASING hint key to VALUE_ANTIALIAS_ON does not cause such lines to suddenly become twice as wide and half as opaque, it is desirable to have the model specify a path for such lines so that they completely cover a particular set of pixels to help increase their crispness.

    Java 2D API maintains compatibility with JDK 1.1 rendering behavior, such that legacy operations and existing renderer behavior is unchanged under Java 2D API. Legacy methods that map onto general draw and fill methods are defined, which clearly indicates how Graphics2D extends Graphics based on settings of Stroke and Transform attributes and rendering hints. The definition performs identically under default attribute settings. For example, the default Stroke is a BasicStroke with a width of 1 and no dashing and the default Transform for screen drawing is an Identity transform.

    The following two rules provide predictable rendering behavior whether aliasing or antialiasing is being used.

    • Device coordinates are defined to be between device pixels which avoids any inconsistent results between aliased and antaliased rendering. If coordinates were defined to be at a pixel's center, some of the pixels covered by a shape, such as a rectangle, would only be half covered. With aliased rendering, the half covered pixels would either be rendered inside the shape or outside the shape. With anti-aliased rendering, the pixels on the entire edge of the shape would be half covered. On the other hand, since coordinates are defined to be between pixels, a shape like a rectangle would have no half covered pixels, whether or not it is rendered using antialiasing.
    • Lines and paths stroked using the BasicStroke object may be "normalized" to provide consistent rendering of the outlines when positioned at various points on the drawable and whether drawn with aliased or antialiased rendering. This normalization process is controlled by the KEY_STROKE_CONTROL hint. The exact normalization algorithm is not specified, but the goals of this normalization are to ensure that lines are rendered with consistent visual appearance regardless of how they fall on the pixel grid and to promote more solid horizontal and vertical lines in antialiased mode so that they resemble their non-antialiased counterparts more closely. A typical normalization step might promote antialiased line endpoints to pixel centers to reduce the amount of blending or adjust the subpixel positioning of non-antialiased lines so that the floating point line widths round to even or odd pixel counts with equal likelihood. This process can move endpoints by up to half a pixel (usually towards positive infinity along both axes) to promote these consistent results.

    The following definitions of general legacy methods perform identically to previously specified behavior under default attribute settings:

    • For fill operations, including fillRect, fillRoundRect, fillOval, fillArc, fillPolygon, and clearRect, fill can now be called with the desired Shape. For example, when filling a rectangle:
       fill(new Rectangle(x, y, w, h));
       
      is called.

    • Similarly, for draw operations, including drawLine, drawRect, drawRoundRect, drawOval, drawArc, drawPolyline, and drawPolygon, draw can now be called with the desired Shape. For example, when drawing a rectangle:
       draw(new Rectangle(x, y, w, h));
       
      is called.

    • The draw3DRect and fill3DRect methods were implemented in terms of the drawLine and fillRect methods in the Graphics class which would predicate their behavior upon the current Stroke and Paint objects in a Graphics2D context. This class overrides those implementations with versions that use the current Color exclusively, overriding the current Paint and which uses fillRect to describe the exact same behavior as the preexisting methods regardless of the setting of the current Stroke.
    The Graphics class defines only the setColor method to control the color to be painted. Since the Java 2D API extends the Color object to implement the new Paint interface, the existing setColor method is now a convenience method for setting the current Paint attribute to a Color object. setColor(c) is equivalent to setPaint(c).

    The Graphics class defines two methods for controlling how colors are applied to the destination.

    1. The setPaintMode method is implemented as a convenience method to set the default Composite, equivalent to setComposite(new AlphaComposite.SrcOver).
    2. The setXORMode(Color xorcolor) method is implemented as a convenience method to set a special Composite object that ignores the Alpha components of source colors and sets the destination color to the value:
       dstpixel = (PixelOf(srccolor) ^ PixelOf(xorcolor) ^ dstpixel);

      protected Graphics2D()
      Constructs a new Graphics2D object. Since Graphics2D is an abstract class, and since it must be customized by subclasses for different output devices, Graphics2D objects cannot be created directly. Instead, Graphics2D objects must be obtained from another Graphics2D object, created by a Component, or obtained from images such as BufferedImage objects.

      Inherited member indicator clearRect Reveal DetailHide Detail
      abstract 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.
      public abstract void clearRect(int x, int y, int width, int height)
      Description copied from class: Graphics
      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.

      Ordinary member indicator clip Reveal DetailHide Detail
      abstract void clip(Shape s)
      Intersects the current Clip with the interior of the specified Shape and sets the Clip to the resulting intersection.
      public abstract void clip(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.
      Inherited member indicator clipRect Reveal DetailHide Detail
      abstract void clipRect(int x, int y, int width, int height)
      Intersects the current clip with the specified rectangle.
      public abstract void clipRect(int x, int y, int width, int height)
      Description copied from class: Graphics
      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

      abstract 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 abstract void copyArea(int x, int y, int width, int height, int dx, int dy)
      Description copied from class: Graphics
      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.
      Inherited member indicator create Reveal DetailHide Detail
      abstract Graphics create()
      Creates a new Graphics object that is a copy of this Graphics object.
      public abstract Graphics create()
      Description copied from class: Graphics
      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.
      Inherited member indicator create Reveal DetailHide Detail
      Graphics create(int x, int y, int width, int height)
      Creates a new Graphics object based on this Graphics object, but with a new translation and clip area.
      public Graphics create(int x, int y, int width, int height)
      Description copied from class: Graphics
      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:

      • The new graphics context is translated by (x, y). That is to say, the point (0, 0) in the new graphics context is the same as (x, y) in the original graphics context.
      • The new graphics context has an additional clipping rectangle, in addition to whatever (translated) clipping rectangle it inherited from the original graphics context. The origin of the new clipping rectangle is at (0, 0), and its size is specified by the width and height arguments.

      Parameters:
      x - the x coordinate.
      y - the y coordinate.
      width - the width of the clipping rectangle.
      height - the height of the clipping rectangle.
      Returns:
      a new graphics context.

      Inherited member indicator dispose Reveal DetailHide Detail
      abstract void dispose()
      Disposes of this graphics context and releases any system resources that it is using.
      public abstract void dispose()
      Description copied from class: Graphics
      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.

      Overridden member indicator draw3DRect Reveal DetailHide Detail
      void draw3DRect(int x, int y, int width, int height, boolean raised)
      Draws a 3-D highlighted outline of the specified rectangle.
      public void draw3DRect(int x, int y, int width, int height, boolean raised)
      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. This method uses the current Color exclusively and ignores the current Paint.

      Overrides:
      draw3DRect in class Graphics
      Parameters:
      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.

      Inherited member indicator drawArc Reveal DetailHide Detail
      abstract 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.
      public abstract void drawArc(int x, int y, int width, int height, int startAngle, int arcAngle)
      Description copied from class: Graphics
      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.

      Inherited member indicator drawBytes Reveal DetailHide Detail
      void drawBytes(byte[] data, int offset, int length, int x, int y)
      Draws the text given by the specified byte array, using this graphics context's current font and color.
      public void drawBytes(byte[] data, int offset, int length, int x, int y)
      Description copied from class: Graphics
      Draws the text given by the specified byte array, using this graphics context's current font and color. The baseline of the first character is at position (x, y) in this graphics context's coordinate system.

      Use of this method is not recommended as each byte is interpreted as a Unicode code point in the range 0 to 255, and so can only be used to draw Latin characters in that range.

      Parameters:
      data - the data to be drawn
      offset - the start offset in the data
      length - the number of bytes that are drawn
      x - the x coordinate of the baseline of the text
      y - the y coordinate of the baseline of the text
      Throws:
      java.lang.NullPointerException - if data is null.
      java.lang.IndexOutOfBoundsException - if offset or lengthis less than zero, or offset+length is greater than the length of the data array.

      abstract boolean drawImage(Image img, java.awt.geom.AffineTransform xform, java.awt.image.ImageObserver obs)
      Renders an image, applying a transform from image space into user space before drawing.
      public abstract boolean drawImage(Image img, java.awt.geom.AffineTransform xform, 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 specified image to be rendered. This method does nothing if img is null.
      xform - the transformation from image space into user space
      obs - the ImageObserver to be notified as more of the Image is converted
      Returns:

      public abstract boolean drawImage(Image img, int x, int y, Color bgcolor, java.awt.image.ImageObserver observer)
      Description copied from class: Graphics
      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 completely loaded and its pixels are no longer being changed, then drawImage returns true. Otherwise, drawImage returns false and as more of the image becomes available or it is time to draw another frame of animation, the process that loads the image notifies the specified image observer.

      Parameters:
      img - the specified image to be drawn. This method does nothing if img is null.
      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:
      false if the image pixels are still changing; true otherwise.

      public abstract boolean drawImage(Image img, int x, int y, java.awt.image.ImageObserver observer)
      Description copied from class: Graphics
      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 completely loaded and its pixels are no longer being changed, then drawImage returns true. Otherwise, drawImage returns false and as more of the image becomes available or it is time to draw another frame of animation, the process that loads the image notifies the specified image observer.

      public abstract boolean drawImage(Image img, int x, int y, int width, int height, Color bgcolor, java.awt.image.ImageObserver observer)
      Description copied from class: Graphics
      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 loads 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. 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.
      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:
      false if the image pixels are still changing; true otherwise.

      Description copied from class: Graphics
      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.

      Parameters:

      Description copied from class: Graphics
      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 loads 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. This method does nothing if img is null.
      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.
      Returns:
      false if the image pixels are still changing; true otherwise.

      public abstract void fillArc(int x, int y, int width, int height, int startAngle, int arcAngle)
      Description copied from class: Graphics
      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.

      Parameters:
      x - the x coordinate of the upper-left corner of the arc to be filled.
      y - the y coordinate of the upper-left corner of the arc to be filled.
      width - the width of the arc to be filled.
      height - the height of the arc to be filled.
      startAngle - the beginning angle.
      arcAngle - the angular extent of the arc, relative to the start angle.

      public boolean hitClip(int x, int y, int width, int height)
      Description copied from class: Graphics
      Returns true if the specified rectangular area might intersect the current clipping area. The coordinates of the specified rectangular area are in the user coordinate space and are relative to the coordinate system origin of this graphics context. This method may use an algorithm that calculates a result quickly but which sometimes might return true even if the specified rectangular area does not intersect the clipping area. The specific algorithm employed may thus trade off accuracy for speed, but it will never return false unless it can guarantee that the specified rectangular area does not intersect the current clipping area. The clipping area used by this method can represent the intersection of the user clip as specified through the clip methods of this graphics context as well as the clipping associated with the device or image bounds and window visibility.
      Parameters:
      x - the x coordinate of the rectangle to test against the clip
      y - the y coordinate of the rectangle to test against the clip
      width - the width of the rectangle to test against the clip
      height - the height of the rectangle to test against the clip
      Returns:
      true if the specified rectangle intersects the bounds of the current clip; false otherwise.

      Parameters:
      sx - the amount by which X coordinates in subsequent rendering operations are multiplied relative to previous rendering operations.
      sy - the amount by which Y coordinates in subsequent rendering operations are multiplied relative to previous rendering operations.
      Ordinary member indicator setBackground Reveal DetailHide Detail
      abstract void setBackground(Color color)
      Sets the background color for the Graphics2D context.
      public abstract void setBackground(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)

      public abstract void setClip(Shape clip)
      Description copied from class: Graphics
      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.
      Parameters:
      clip - the Shape to use to set the clip

      Ordinary member indicator setComposite Reveal DetailHide Detail
      abstract void setComposite(Composite comp)
      Sets the Composite for the Graphics2D context.
      public abstract void setComposite(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.

      Ordinary member indicator setTransform Reveal DetailHide Detail
      abstract void setTransform(java.awt.geom.AffineTransform Tx)
      Overwrites the Transform in the Graphics2D context.
      public abstract void setTransform(java.awt.geom.AffineTransform Tx)
      Overwrites the Transform in the Graphics2D context. WARNING: This method should never be used to apply a new coordinate transform on top of an existing transform because the Graphics2D might already have a transform that is needed for other purposes, such as rendering Swing components or applying a scaling transformation to adjust for the resolution of a printer.

      To add a coordinate transform, use the transform, rotate, scale, or shear methods. The setTransform method is intended only for restoring the original Graphics2D transform after rendering, as shown in this example:

      // Get the current transform AffineTransform saveAT = g2.getTransform(); // Perform transformation g2d.transform(...); // Render g2d.draw(...); // Restore original transform g2d.setTransform(saveAT);
      Parameters:
      Tx - the AffineTransform that was retrieved from the getTransform method

      Inherited member indicator setXORMode Reveal DetailHide Detail
      abstract 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.
      public abstract void setXORMode(Color c1)
      Description copied from class: Graphics
      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
      Ordinary member indicator shear Reveal DetailHide Detail
      abstract void shear(double shx, double shy)
      Concatenates the current Graphics2D Transform with a shearing transform.
      public abstract 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   ]
       
      Parameters:

      Ordinary member indicator transform Reveal DetailHide Detail
      abstract 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.
      public abstract 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
