In this article, we are going to see how to set the perPixelTargetFind of a Path using Fabric.js. The Path in Fabric.js is movable and can be stretched according to requirement. Further, the Path can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.
Approach:
- To make it possible we are going to use a JavaScript HTML5 canvas library called Fabric.js.
- After importing the library, we will create a canvas block in the body tag that will contain the path.
- After this, we will initialize instances of Canvas and Path provided by Fabric.js and set the perPixelTargetFind property value of the path using perPixelTargetFind property.
Syntax:
fabric.Path('path', {
perPixelTargetFind: Boolean
});Parameters: This function accepts a single parameter as mentioned above and described below:
- perPixelTargetFind: It specifies the string value of perPixelTargetFind property.
The below example illustrates the use of Fabric.js Path perPixelTargetFind property in JavaScript:
Example:
HTML
<!DOCTYPE html> <html>
<head>
<!-- FabricJS CDN -->
<script src=
</script>
</head>
<body>
<div style="text-align: center;width: 400px;">
<h1 style="color: green;">
GeeksforGeeks
</h1>
<b>
Fabric.js | Path perPixelTargetFind Property
</b>
</div>
<div style="text-align: center;">
<canvas id="canvas" width="400" height="200"
style="border:1px solid green;">
</canvas>
</div>
<script>
// Initiate a Canvas instance
var canvas = new fabric.Canvas("canvas");
var geek = new fabric.Path(
'M 0 0 L 100 100 L 0 100 z', {
fill:'green',
perPixelTargetFind: true
});
canvas.add(geek);
canvas.centerObject(geek);
</script>
</body>
</html>
