What's the technology that Gravatar uses for us to resize our images when we upload it?

Is it using the HTML5 Canvas API through JavaScript?

I'm pretty sure it's just js. Unless they are doing Agile for their front-end and already went through another cycle. I remember looking at it when I was doing Wordpress stuff a couple of years back.

Edit to answer question: No, I don't think you need the canvas element unless they have significantly changed their code-base in the last year.

  • is canvas required for that technology?

I would think it's ImageMagick. Gravatar has been around for quite a while.

  • i don't get you.. the technology used simply had to be javascript right? i mean I know that It is javascript but I do not know if it is simply javascript or javascript with canvas..
