HTMLWeb DevelopmentFront End Technology

Use the following method to create a pattern with HTML5 Canvas: createPattern(image, repetition)− This method will use an image to create the pattern. The second argument could be a string with one of the following values: repeat, repeat-x, repeat-y, and no-repeat. If the empty string or null is specified, repeat will be assumed.


You can try to run the following code to learn how to create a pattern −

         #test {
            margin: 0px auto;
         function drawShape(){
            // get the canvas element using the DOM
            var canvas = document.getElementById('mycanvas');
            // Make sure we don't execute when canvas isn't supported
            if (canvas.getContext){
               // use getContext to use the canvas for drawing
               var ctx = canvas.getContext('2d');
               // create new image object to use as pattern
               var img = new Image();
               img.src = 'images/pattern.jpg';
               img.onload = function(){
                  // create pattern
                  var ptrn = ctx.createPattern(img,'repeat');
                  ctx.fillStyle = ptrn;
            } else {
               alert('You need Safari or Firefox 1.5+ to see this demo.');
   <body id = "test" onload = "drawShape();">
      <canvas id = "mycanvas"></canvas>
