Image constructor / inheritance not consistent #172

lgrignon · 2016-10-14T14:24:14Z

in Javascript, you can do

var img = new Image(200, 200);

and in TypeScript

var img: HTMLImageElement = new Image(200, 200);

due to the declaration in lib.d.ts :

declare var Image: {new(width?: number, height?: number): HTMLImageElement; };

In JSweet, this is impossible, jsweet.dom.Image does not extend HTMLImageElement and jsweet.dom.Globals.Image is an instance of jsweet.dom.Image which is no use for this case.

Even worse:

HTMLImageElement img = any(new Image(200, 200));

produces:

var img = {};

NB: there is an obvious workaround with

HTMLImageElement img = document.createElement("img");
img.width = 200;
img.height = 200;
