Examples of java.awt.Graphics2D.drawImage()

java.awt.Graphics2D.drawImage()
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. @param img the specified image to be rendered. This method does nothing if img is null. @param xform the transformation from image space into user space @param obs the {@link ImageObserver}to be notified as more of the Image is converted @return true if the Image is fully loaded and completely rendered, or if it's null; false if the Image is still being loaded. @see #transform @see #setTransform @see #setComposite @see #clip @see #setClip
