jqEziDraw is a drawing control


jqEziDraw is a jQuery drawing control with these features:

  • 5 predefined shapes (line, rectangle, rounded corner rectangle, ellipse)
  • You can defined new shapes.
  • Selecting Shapes by click in drawing board or by using shapes history.
  • Shapes History with the ability to reorder, move, resize and delete them.
  • Hide/Show shapes.
  • Very basic shape style support (Line colour, Fill colour, Line Size).
  • Multiple draw board in a page.


I wanted to learn how to deal with canvas in JavaScript for a long time and I decided to build a tiny control to get familiar with canvas. jqEziDraw is not a complete and wellformed code and I want to complete it before published it.

I also haven’t made much progress in the last few months because I haven’t had as much time for it, so I decide to published it (as is).

Using the Code


You need to include 4 files to your page:

  1. jQuery
  2. jqEziDraw.js
  3. jqEziDrawShapes.js
  4. jqEziDraw.css
    <link rel="stylesheet" type="text/css" href="jqEziDraw.css" />
    <script type="text/javascript" src="../common/jquery-1.9.0.min.js"></script>
    <script type="text/javascript" src="jqEziDraw.js"></script>
    <script type="text/javascript" src="jqEziDrawShapes.js"></script> 

Full Featured Sample

To create draw board with Toolbox, Shapes history and Shape style, you need to call the eziDraw plugin with these parameters:


You need one <canvas> element and 3 <div> elements like these:

    <div class='ToolsBox' id='tools'></div>
    <canvas class='CanvasBox' id="myCanvas" width="600" height="600"></canvas>
    <div style='display:inline-block;width:210px;vertical-align:top;'>
        <div class='HistoryBox' style='border:1px solid #000;'>
            <div style='color:#FFFFFF;text-align:center'>Shapes</div>
            <div id='history' style='height:350px;vertical-align:top;overflow-y:scroll;overflow-x:none;'></div>
        <div class='StyleBox' style='border:1px solid #000;' >
            <div style='color:#FFFFFF;text-align:center'>Shape Style</div>
            <div id='ShapeStyle' style='height:70px;vertical-align:top;overflow-y:none;overflow-x:none;'></div>

All 3 options (shapeStyle, tools and history) are optional.

Create New Shape

All shapes are defined in jqEziDrawShape.js and you can easily create a new shape.

Shapes defined in JSON format:

        icon:'<img alt="" src=“icon.png” />',
            //draw method defined how shape must rendered
            //for example the below code render a simple line    

What's Next?

  • Edit shape style (properties)
  • Save/Load settings and drawings in Local Storage
