Adding background to merged image

[JRadl]

I need to merge several transparent images and then add a color background based on user selected hex code. Is it possible to do that somehow?

It's not currently possible but support for that could be implemented.

If you add this functionality in clean and well documented way I'd happily accept a pull request.

Alternatively, if you don't want to implement it yourself you could sponsor me to implement it. I could do this for $50.

var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
...
ctx.fillStyle = "white";
ctx.fillRect(0, 0, canvas.width, canvas.height);

Just add the last two lines to fill the background in the index.js
