Examples of java.awt.Graphics.drawImage()

java.awt.Graphics.drawImage()
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. @param img the specified image to be drawn. This method doesnothing if img is null. @param x the x coordinate. @param y the y coordinate. @param observer object to be notified as more of the image is converted. @return false if the image pixels are still changing;true otherwise. @see java.awt.Image @see java.awt.image.ImageObserver @see java.awt.image.ImageObserver#imageUpdate(java.awt.Image,int,int,int,int,int)
