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 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.

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.
