Re: [actionstep-core] ASsymbolImageRep enhancement

hi

I was using repSizeForClip().

and you're right about _root, I figured it out later.

It leaves me with my question :

how do I get the size of the symbol before the draw cycle ?

because for instance I think If I want to use NSImage.setImageAlignment()
and that I don't set a size for the image (and I want the image to the size
of the symbol) it won't work (since the size() yields widht=undefined and
height=undefined)

I resort to calling repSizeForClip passing the view mcBounds as the base
clip like :

var size_mc:MovieClip = win.rootView
().mcBounds().createEmptyMovieClip("__SIZE_MC__",_root.getNextHighestDepth());
var symbolSize = rep.repSizeForClip(size_mc);
size_mc.removeMovieClip();

I also thought about passing the current view to the rep ...
