In this article, we are going to set the horizontal scale of a canvas Line in Fabric.js. The Line in Fabric.js is movable and can be stretched according to requirements. Further, the Line can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.
To make this possible we are going to use a JavaScript library called Fabric.js. After importing the library, we will create a canvas block in the body tag which will contain the Line. After this, we will initialize instances of Canvas and Line provided by Fabric.js, set the horizontal scale of a Line using the scaleX property, and render the Line on the Canvas as given below.
Syntax:
fabric.Line ({ scaleX : number });
Parameters: This property holds single value as mentioned above and described below:
- scaleX: It is a number value that specifies the horizontal scale of a canvas Line.
Example 1:
HTML
<!DOCTYPE html> < html > < head > < script src = </ script > </ head > < body > < h1 >fabric.js | line scaleX property</ h1 > < canvas id = "canvas" width = "600" height = "200" style = "border:1px solid #000000;" > </ canvas > < script > // Initialize a Canvas instance var canvas = new fabric.Canvas("canvas"); // Initialize a Line instance var line = new fabric.Line([150, 10, 220, 150], { stroke: 'green', // Set the scaleX of the line scaleX: 3 }); canvas.add(line); </ script > </ body > </ html > |
Output:
Example 2:
HTML
<!DOCTYPE html> < html > < head > < script src = </ script > </ head > < body > < h1 >fabric.js | line scaleX property</ h1 > < canvas id = "canvas" width = "600" height = "200" style = "border:1px solid #000000;" > </ canvas > < script > // Initiate a Canvas instance var canvas = new fabric.Canvas("canvas"); // Initiate a Line instance var line = new fabric.Line([150, 10, 220, 150], { stroke: 'green', // Set the scaleX of the line scaleX: 2 }); canvas.add(line); </ script > </ body > </ html > |
Output:
