<strong>Fabric.js</strong> is a powerful and simple<br>Javascript <strong>HTML5 canvas library</strong>
</h1>
<h4 style="margin: 5px !important">Fabric provides <strong>interactive object model</strong> on top of canvas element</h4>
<h4 style="margin: 5px !important">Fabric also has <strong>SVG-to-canvas</strong> (and <strong>canvas-to-SVG</strong>) parser</h4>
<div style="position: relative">
<canvas id="intro-canvas" width="500" height="1850"></canvas>
<div class="tooltip simple-shapes">
Using Fabric.js, you can create and populate objects on canvas; objects like <b>simple geometrical shapes</b>
</div>
<div class="tooltip complex-shapes">
or <b>complex shapes</b> consisting of hundreds or thousands of simple paths
</div>
<div class="tooltip images">
or good old <b>images</b>
</div>
<div class="tooltip text">
You can add <b>text</b> and dynamically manipulate its <b>size, alignment, font family</b>, and other properties
</div>
<div class="tooltip gradients">
You can give any shape a <b>gradient</b>
</div>
<div class="tooltip filters">
and apply <b>image filters</b> to images
</div>
<div class="tooltip animation">
There's built-in <b>animation</b> support
</div>
<div class="tooltip groups">
You can <b>group</b> objects together, and manipulate them at the same time
</div>
<div class="tooltip shadows">
You can add <b>shadow</b> to any object. Or make it <b>draggable</b> only by its content. Try this star →
</div>
<div class="tooltip flipping">
Objects can be easily <b>flipped</b> in any direction. Or <b>locked</b> in movement, scaling, etc.<br> ← Try these cats.
</div>
<div class="tooltip events">
There's an extensive <b>event</b> system
</div>
<div class="tooltip clipping">
You can <b>clip</b> any object to any shape
</div>
<div class="tooltip patterns">
or use <b>pattern</b> to fill its content
</div>
<div class="tooltip freedrawing">
and, of course, use <b>free drawing</b> to create anything you like
