Drawing A Svg File On A Html5 Canvas At A Specific Time

I found the topic Drawing an SVG file on a HTML5 canvas about rendering SVG. Is there a way to draw SVG animated file at specific moment of time? I mean, how to change the code var

Solution 1:

You can simply use setTimeout to defer the insertion of the square, in this fashion :

var delayInMilliseconds = 3000;

img.onload = function() {
    setTimeout(function() {
        // This will happend 3 seconds after page load
        ctx.drawImage(img, 0, 0);
    }, delayInMilliseconds);
}
img.src = "http://upload.wikimedia.org/wikipedia/commons/d/d2/Svg_example_square.svg";

In case you want to be able to specify a date and time for the event, use a custom function to count the time left to the target date :

functiongetTimeTo(date) {
    var time = date.getTime() - Date.now();
    returntime;
}

And replace delayInMilliseconds with getTimeTo(targetDate). See this fiddle for experimenting.
