how read pixel of an image without canvas

问题

How to get all pixel info (RGB) of an image using javascript. I can't use CANVAS.

Just reading an image from local disk and parse the pixels. I don't want to render img on the page.

Thanks.

That is not possible. Javascript cannot read plain binary data from files on local disk (for obvious security reasons).
