The package defines a convenient interface to put any LaTeX material on top of included graphics. The LaTeX material may also be rotated and typeset on top of a white box overshadowing the graphics. The coordinates of the LaTeX boxes are given relative to the original, unscaled graphics; when the graphics is rescaled, the LaTeX annotations stay at their right places (unless you do something extreme). In a draft mode, the package enables you to draw a coordinate grid over the picture for easy adjustment of positions of the annotations.
