SVG resizing in IE9

Question

I've got an inline SVG element inside a div, which scales to fit the browser window. When the browser is resized, the SVG image resizes with it, so that all the image is visible, and it keeps the same proportions.

However, in IE9, the image is much smaller, and doesn't resize. Taking off the viewBox scales the image to the full size, which is too big, and it still doesn't resize.

I've found that by setting the width and height of the containing div will make the image larger, but only with fixed pixels, rather than 100%, which is what I need.

This jsfiddle shows the problem in action (i.e. it's fine in Chrome, and not fine in IE9). Resizing the frame borders should make the image resize.

<div id="outer">
    <svg viewBox="0 0 700 1000"  xmlns=http://www.w3.org/2000/svg>
        <g transform="rotate(90, 350, 350)" id="pitch-rotated">

I haven't tested this in IE yet but if you're looking to use 100% width and height the I assume you either want it to be 'fullscreen' or to fit within a container. Since you also mentioned that it scales correctly when...

setting the width and height of the containing div will make the image larger, but only with fixed pixels

...then you can use JS for this. With jQuery, for example, you can do the following:

$(window).resize(function()
{
    $('#outer').css({
        width: $(window).width() + 'px',
        height: $(window).height() + 'px'
    })
});

This is assuming that you want your #outer container to be the width and height of the window when the window is resized.
