HTML5 canvas provides capabilities to create nice shadows around the drawings. All drawing operations are affected by the four global shadow attributes.
| Sr.No. | Property and Description |
|---|---|
| 1 | shadowColor [ = value ] This property returns the current shadow color and can be set, to change the shadow color. |
| 2 | shadowOffsetX [ = value ] This property returns the current shadow offset X and can be set, to change the shadow offset X. |
| 3 | shadowOffsetY [ = value ] This property returns the current shadow offset Y and can be set, change the shadow offset Y. |
| 4 | shadowBlur [ = value ] This property returns the current level of blur applied to shadows and can be set, to change the blur level. |
Example
You can try to run the following code to create shadows:
<!DOCTYPE HTML>
<html>
<head>
<style>
#test {
width: 100px;
height:100px;
margin: 0px auto;
}
</style>
<script type>
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');
ctx.shadowOffsetX = 2;
ctx.shadowOffsetY = 2;
ctx.shadowBlur = 2;
ctx.shadowColor = "rgba(0, 0, 0, 0.5)";
ctx.font = "20px Times New Roman";
ctx.fillStyle = "Black";
ctx.fillText("This is shadow test", 5, 30);
} else {
alert('You need Safari or Firefox 1.5+ to see this demo.');
}
}
</script>
</head>
<body id = "test" onload = "drawShape();">
<canvas id = "mycanvas"></canvas>
</body>
</html>
