EPUB3: resize SVG in javascript

I'm working on a EPUB3 with a SVG inline image with animation and interactivity.
I'd like to change the SVG size, according to pixel width and height of the ebook page, because ADE desktop often opens ebook in landscape mode instead portrait ad "cut" the SVG in half.
I try window.innerWidth, window.innerHeight, it worked in iBooks, but I got wrong values in ADE. I try outerWidth / outerHeight, it worked in ADE, but I got wrong values in iBooks...

Suggestion?


Thank you
