I want to use JSChart (http://www.jscharts.com/) to generate a dynamic chart.
It uses a <canvas> object.
Furthermore I want to save the generated Chart as an image (to put in a pdf file) on the serverside.
Is it possible to save a JavaScript generated image as jpg or png on the serverside?
Preferably the solution should work with Ruby and Ruby On Rails.
I think this uses a
<canvas>object to render the charts, can’t tell without downloading and it requires registration, so no. If it does, perhaps take a look at Canvas2Image, that returns the canvas as a data URL, base64 encoded image, which could be sent back to the server via an AJAX call.
