The stroke and stroke width properties are used to set the stroke color and stroke width of the canvas circle. The Circle class contains different properties, but to set the stroke color and width, we use the stroke and stroke-width properties. The strokeWidth property is used to specify the width of the canvas circle.
Fabric.js Circle class is used to provide circular shapes through Fabric.Circle objects. Circle object is used to provide a circular shape and the circle is movable and can be stretched as per the requirement. The stroke, color, width, height and fill color of the circle are all customizable. Compared with the canvas class, the Circle class provides rich functions.
grammar
The following is the syntax of text objects -
fabric.Circle({ radius: number, stroke: string, strokeWidth: number });
parameter
radius - used to specify the radius of the circle
Stroke - Specifies the color of the stroke.
Stroke width - Used to specify the width of the stroke
step
Follow the steps given below to set the horizontal tilt of the canvas circle using Fabric.js -
Step 1 - Include the Fabric.js library in the HTML file
Step 2 - Create a new canvas element in the HTML file
Step 3 - Initialize the canvas element in JavaScript code
Step 4 - Create a new Fabric.js Circle class object and set the skewX property to the desired circle value
Step 5 - Add Circle Object to Canvas
Example
Let’s see how to set the stroke color and stroke width of the canvas circle using Fabric.js -
<html> <head> <script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/3.6.3/fabric.min.js"></script> </head> <body> <h2 id="Setting-the-Stroke-Color-and-Stroke-Width-of-a-Canvas-Circle">Setting the Stroke Color and Stroke Width of a Canvas Circle</h2> <p>Please click on the canvas circle to see the controlling corners.</p> <p>Strke color: green, stoke width: 20</p> <canvas id="strokecanvas"></canvas> <script> // Initiating a canvas instance var canvas = new fabric.Canvas('strokecanvas'); // Create a instance of fabric.Circle Class var circle6 = new fabric.Circle({ top: 50, left: 50, radius: 70, stroke: "green", strokeWidth: 20 }); // Adding the Canvas canvas.add(circle6); canvas.setWidth(document.body.scrollWidth); canvas.setHeight(350); </script> </body> </html>
This code will create a new canvas circle element with the specified ID, create a new Fabric.js Circle class object, and set the stroke color and stroke width of the circle using the stroke and stroke width properties, and add the circle object to the canvas. The circle will appear tilted horizontally on the canvas.
Example
Let's look at another example, we can set the stroke color and stroke width of the canvas circle by using the stroke and stroke width methods and the left, top, fill, radius and other properties.
<html> <head> <script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/3.6.3/fabric.min.js"></script> </head> <body> <h2 id="Setting-the-Stroke-Color-and-Stroke-Width-of-a-Canvas-Circle">Setting the Stroke Color and Stroke Width of a Canvas Circle</h2> <p>Please click on the canvas circle to see the controlling corners.</p> <p>Strke color: blue, stoke width: 20</p> <canvas id="canvasstroke"></canvas> <script> var canvas = new fabric.Canvas('canvasstroke'); var circle5 = new fabric.Circle({ top: 60, left: 60, fill: "violet", radius: 70, stroke: "blue", strokeWidth: 20 }); canvas.add(circle5); canvas.setWidth(document.body.scrollWidth); canvas.setHeight(500); </script> </body> </html>
This code will create a new canvas circle element with the specified ID and size, create a new Fabric.js Circle class object, and use the strokeWidth property to set the canvas circle to the stroke color and stroke width, and set the stroke width to the canvas circle element. Class object added to canvas. The circle will appear on the canvas with the dimensions we defined in the example.
in conclusion
In this article, we demonstrate through examples how to set the stroke width and stroke color of a canvas circle. We see two different examples here where we use the stroke and stroke-width properties to set the stroke width and color of a circular canvas. In the first example, we use the Stroke and StrokeWidth properties to set the color and width of the canvas circle. For the second example, we used the Stroke and StrokeWidth property methods with various size parameters (such as Left, Top, Fill, etc.) to set the width and color stroke of the circular canvas.
The above is the detailed content of How to set the stroke width of a canvas circle using Fabric.js?. For more information, please follow other related articles on the PHP Chinese website!

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
