IE8 - Scale value seems to be incorrect.

[christian-thomas]

Just testing my application through IE8 (Guillotine v1.3.0), and it appears that 'scale' is being reported incorrectly.

I've got the following JS, using exactly the same image:

$image.guillotine({
    width:      480,
    height:     480,
    onChange:   function(event){

        $form
            .find('[name="image_data"]')
            .val(JSON.stringify(event));
    }
});

$image.guillotine('fit');

Then when I post the form data to my server, I get the following outputs:

IE8

[2015-01-14 12:51:03] staging.INFO: Image Data {"image_data":"[object] (stdClass: {\"scale\":2.962962962962963,\"angle\":0,\"x\":80,\"y\":0,\"w\":480,\"h\":480})"} []

Chrome

[2015-01-14 12:51:09] staging.INFO: Image Data {"image_data":"[object] (stdClass: {\"scale\":0.625,\"angle\":0,\"x\":80,\"y\":0,\"w\":480,\"h\":480})"} []

Image below if you need it for testing purposes.

If the image is zoomed the same amount in both cases and the scale is different then there's something off, but first we need to determine that in each test the initial zoom is the same and that the zoom applied to both is effectively the same.

Let me know how you applied zoom in both tests and post the complete code, including not only where you init the plugin but also where you bind events to actions or wherever you use the plugin's API.

Yep, I should've mentioned.

There's been no zooming or any events applied to the images. They're just in the same state that they are when they're the page first loads on both browsers.

I also tried IE9, and that's fine I believe - Reports the same as Chrome.

I can't reproduce the issue, I tested on Chromium for Linux and on IE8 in a virtual WinXP, both behave the same. Scale is 0.625 in both cases.

I changed the code in the demo to match yours:

picture.guillotine({ width: 480, height: 480, eventOnChange: 'guillotinechange' })
picture.guillotine('fit')

I'll see if I can duplicate your demo code and give you a bit more insight into this tomorrow.
