Each frame of an animation is associated with an OCG that is made visible or invisible in a dynamic fashion by means of Adobe Reader's built-in JavaScript engine.

 where \verb+<transparency ID>+ is an integer number that identifies the transparency to be drawn into the current animation frame. As pointed out above, the transparencies are consecutively numbered in the order of their inclusion, starting at zero. The optional postfix `\verb+x<number of frames>+' specifies the number of consecutive frames the transparency is to appear within. If omitted, a postfix of `\verb+x1+' is assumed, which causes the transparency to be shown in the current frame only. Obviously, \verb+<number of frames>+ must be a non-negative integer number. The meaning of postfix `\verb+x0+' is special; it causes the transparency to be shown in all frames, starting with the current one, until the end of the animation.
 
-Note, that the order in which transparency specifications appear in the timeline file determines their depth level. The animation may be thought of as a pile of transparencies. Transparencies are always put on top of that pile, possibly overdrawing objects that are on previously deposited transparencies. Once on the pile, each transparency remains at its place for the specified number of frames and is removed afterwards. That is, for a transparency to appear always on top it must be put to the rightmost end of each line in the timeline file.
