The HTML inside the <body> looks like this:
<div id="handiv" style="display:inline-block;width:500px;"> </div> <div id="handiv22" style="display:inline-block;width:500px;"> </div> <script> function init() { var a = new HAnisF(); a.setup('hanist1.txt','handiv') var b = new HAniSF(); b.setup('filenames = TIR1.GIF, TIR2.GIF, TIR3.GIF \n imagecan_style=border-radius:30px; \n'+ 'overlay_nonewdiv=t \n overlay_filenames=TMAP.GIF \n active_zoom=t \n controls = startstop, speed, step, looprock, overlay \n' + ' overlay_labels=Map \n controls_style = display:flex;flex-flow:row; \n buttons_style = flex:auto;margin:2px;' , 'handiv22'); } window.onload = init(); </script>(Note also in the 2nd instance, the overlay_filename need only be given once, since it applies to all frames.)
If you needed to reference one of the public methods/functions, you might say:
a.setWindowSize(300,400)for example. Just be certain that the variable "a" is in scope...
