QUESTION

Check for data on canvas and apply class accordingly

Asked 2017-Oct-16 at 13:13

I am using a jQuery plugin called jqscribble to draw to canvas. I would like to grayscale an icon if nothing is drawn to the canvas. As mentioned in the plugin documentation, I can check this using $('...').data('jqScribble').blank and I am using it as such:

A better way to check is to monitor clicks/touches to the canvas assuming those are the only means to draw onto the canvas (if external data is drawn you can always tap into those functions as well though).

If a click or touch is detected, mark canvas "tainted"
When cleared (or saved or other condition), clear taint flag

This way you won't have to pull data from the canvas at all times which has a huge overhead for some type of checks like for example pulling a data-uri and compare it to one that represents an empty canvas.
