Init loaded text with remote web font in Fabric.js

Question

I'm working on a big custom application with Fabric JS and I already did a great job. But I have a problem with init loaded text object that uses a webfont.

As long as that font is local on the client's computer, I works fine, ELSE the webfont is NOT loaded and the text object on the canvas is rendered in a default sans-serif font-family.

Here is, in short, what I do (in this example I use "allstar" as my webfont):

CSS: The css is loaded inside fonts.css in the head before fabric.js

@font-face{
    font-family:'allstar';
    src:
        url('/path-to-fonts/all_star-webfont.eot');
    src:
        url('/path-to-fonts/all_star-webfont.eot?#iefix') format('embedded-opentype'),
        url('/path-to-fonts/all_star-webfont.woff') format('woff'),
        url('/path-to-fonts/all_star-webfont.ttf') format('truetype'),
        url('/path-to-fonts/all_star-webfont.svg#allstarregular') format('svg');
    font-weight:normal;
    font-style:normal
}

Javascript: this is loaded at the bottom of the page inside $(document).ready(function(){})

var textSample = new fabric.Text(text, {
    fontFamily: "allstar",
});
canvas.add(textSample);
canvas.renderAll();

If I use the font elsewhere on the page (e.g.: in a transparent span tag with a dot and the font loaded), it works fine. But I don't think that's a proper way to code.

I Use fabric.js version 1.3.0

The issue:

1. Canvas renders immediately
2. Google loads webfonts
3. Canvas has no idea until the next event that re renders it

The solution:

1. Canvas renders immediately
2. Google loads webfonts with a callback
3. You force render
4. Canvas now has the

http://jsfiddle.net/vvL6f/6/

WebFontConfig = {
    google: { families: [ 'Ribeye::latin', 'Lora::latin', 'Croissant+One::latin', 'Emblema+One::latin', 'Graduate::latin', 'Hammersmith+One::latin', 'Oswald::latin', 'Oxygen::latin', 'Krona+One::latin', 'Indie+Flower::latin', 'Courgette::latin', 'Ranchers::latin' ] }
};

(function() {
    var src = ('https:' === document.location.protocol ? 'https' : 'http') +
        '://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js';

    $.getScript(src, function(data) {      
        // Not sure why I need to run this twice but it makes it load the font and then reposition the font to it's correct coords.
        canvas.renderAll();
        canvas.renderAll();
    });
})();

Short way:

<script src="//ajax.googleapis.com/ajax/libs/webfont/1.4.7/webfont.js"></script>
<script>
WebFont.load({
            google: {
                families: [ 'Abel', 'Aclonica']
            },
            fontinactive: function(familyName, fvd) {
                console.log("Sorry " + familyName + " font family can't be loaded at the moment. Retry later.");
            },
            active: function() {
                // do some stuff with font   
                $('#stuff').attr('style', "font-family:'Abel'");
                var text = new fabric.Text("Text Here", {
                    left: 200,
                    top: 30,
                    fontFamily: 'Abel',
                    fill: '#000',
                    fontSize: 60
                });

                canvas.add(text);
            }
        });
</script>

Long way When do web-fonts load and can you pre-load them?

Using fabric.js and Google Web Fonts, the following code works for me:

Fiddle: http://jsfiddle.net/DanBrown180/vvL6f/

CSS

<Style>
@font-face {
font-family: 'Jolly Lodger';
font-style: normal;
font-weight: 400;
src: local('Jolly Lodger'), local('JollyLodger'),
url(http://themes.googleusercontent.com/static/fonts/jollylodger/v1/RX8HnkBgaEKQSHQyP9itiaRDOzjiPcYnFooOUGCOsRk.woff) format('woff');
}
<style>

Javascript

<script type = "text/javascript">
canvas = new fabric.Canvas('c'); 
var text = new fabric.Text("Web Font Example", {
                    left: 200,
                    top: 30,
                    fontFamily: 'Jolly Lodger',
                    fill: '#000',
                    fontSize: 60
                });

canvas.add(text);
</script>

HTML

<canvas id="c" height="200px" width="400px"></canvas>

Looks like it's because the Google Web Fonts css code uses:

src: local('Jolly Lodger'), local('JollyLodger')

in the CSS

I had the same problem. Font renders correctly after some event is fired.. So after creating an object we can set it active:

var textSample = new fabric.Text(text, {
    fontFamily: "allstar",
});
canvas.add(textSample);
canvas.setActiveObject(textSample); // Selects the object
canvas.renderAll();
