Saving skin dose maps as an image doesn't work in Internet Explorer or Edge

[David Platten]

This should work, I think, but doesn't. I'm using the toDataURL() of the canvas (2d) or renderer (3d). It works fine in Chrome and Firefox.

Does anyone have any ideas?

function downloadCanvas(link, canvasId, filename) {
    link.href = document.getElementById(canvasId).toDataURL();
    link.download = filename;
}

function download3dCanvas(link, filename) {
    link.href = renderer.domElement.toDataURL('image/png');
    link.download = filename;
}

document.getElementById('save2dSkinMap').addEventListener('click', function() {
    downloadCanvas(this, 'skinDoseMap', '2dSkinMap.png');
}, false);

document.getElementById('save3dSkinMap').addEventListener('click', function() {
    download3dCanvas(this, '3dSkinMap.png');
}, false);

Weird that Edge doesn't behave like the others do - you would expect it from IE. I hope the SO helps to fix it, as I've no ideas without doing the research you'll have already done.

Skin dose maps can now be saved in Internet Explorer (tested with v11) and Edge browsers. References issue #61 and fixes issue #375
