Load local file using fromBlob #433

Hi all,

I am using this code to try and load a local Geotiff file. The file is from https://download.osgeo.org/geotiff/samples/usgs/i30dem.tif. Not sure why it is not running. It will never reach document.write('C');

Thanks.

<body>
    <h1>GeoTIFF Load</h1>
    <input type="file" id="file">     
    <script src="geotiff.js"></script>
    <script>
    //https://download.osgeo.org/geotiff/samples/usgs/i30dem.tif
    document.write('A');
    const input = document.getElementById('file');    
    document.write('B');
    input.onchange = async function() {
    const tiff = await fromBlob(input.files[0]);    
    const image = await tiff.getImage();
    const data = await image.readRasters();
    const width = image.getWidth();
    document.write('C');
    }    
    </script>
</body>
</html>
