Set Font Awesome icons as cursor - is this possibl

问题:

Font Awesome has a very good collection of icons to be used in web projects. I want to use one of those icons as cursor (custom cursor).

In my understanding, Custom Cursors need an image url, but I am unable to find the image urls for Font Awesome icons.

Got it!

1. Create a canvas
2. Draw the fa icon on it
3. Change it into a base-64 image url
4. Apply the image on the cursor css style

And I made a demo: http://jsfiddle.net/rqq8B/2/

$(function() {
    var canvas = document.createElement("canvas");
    canvas.width = 24;
    canvas.height = 24;
    //document.body.appendChild(canvas);
    var ctx = canvas.getContext("2d");
    ctx.fillStyle = "#000000";
    ctx.font = "24px FontAwesome";
    ctx.textAlign = "center";
    ctx.textBaseline = "middle";
    ctx.fillText("\uf002", 12, 12);
    var dataURL = canvas.toDataURL('image/png')
    $('body').css('cursor', 'url('+dataURL+'), auto');
});

There is jQuery Awesome Cursor, where you can add font-awesome icons to your cursor by calling only one simple code:

$('body').awesomeCursor('pencil');

Or passing it some options:

$('body').awesomeCursor('pencil', {
  /* your options here */
  size: 22,
  color: 'orange',
  flip: 'horizontal'
});

Disclaimer: I am NOT the author of this library I have just found it.

In the end, I couldn't get @fish_ball's code working reliably, so I just downloaded the images, used gimp to crop and edit them to 32×32px, and used them like this:

.myClass { cursor: url('/static/img/pencil30_32x32.png') 1 30, crosshair }

The 1 30 part sets the mouse pointer 'hotspot' 1px from the left and 30px from the top of the image.

The canvas method mentioned results in blurry cursors.

Using SVG offers better results:

• Download the SVG for the icon you want to use from Encharm's Font-Awesome-SVG-PNG.
• Edit the SVG using a text editor and specify the width and height you'd like to use
  • e.g.: 24 x 24.
  • Keep in mind there's usually a maximum size in the browser (128 x 128 in Firefox.)
• Declare the cursor in CSS, e.g.: cursor: url( '/assets/img/volume-up.svg' ), pointer;
