the class PSPathGraphics method drawImageToPlatform.

/**
     * The various <code>drawImage()</code> methods for
     * <code>WPathGraphics</code> are all decomposed
     * into an invocation of <code>drawImageToPlatform</code>.
     * The portion of the passed in image defined by
     * <code>srcX, srcY, srcWidth, and srcHeight</code>
     * is transformed by the supplied AffineTransform and
     * drawn using PS to the printer context.
     *
     * @param   img     The image to be drawn.
     *                  This method does nothing if <code>img</code> is null.
     * @param   xform   Used to transform the image before drawing.
     *                  This can be null.
     * @param   bgcolor This color is drawn where the image has transparent
     *                  pixels. If this parameter is null then the
     *                  pixels already in the destination should show
     *                  through.
     * @param   srcX    With srcY this defines the upper-left corner
     *                  of the portion of the image to be drawn.
     *
     * @param   srcY    With srcX this defines the upper-left corner
     *                  of the portion of the image to be drawn.
     * @param   srcWidth    The width of the portion of the image to
     *                      be drawn.
     * @param   srcHeight   The height of the portion of the image to
     *                      be drawn.
     * @param   handlingTransparency if being recursively called to
     *                    print opaque region of transparent image
