Canvas2D

Canvas2D is a JavaScript API that provides a drawing surface on a web page. It allows developers to draw graphics, images, and text directly into a designated area of an HTML document using JavaScript. The API offers a rich set of methods for creating 2D shapes, manipulating colors and styles, applying transformations, and rendering images.

The core of Canvas2D is the HTML element. When this element is included in a web page, it creates an area that can be accessed and controlled by JavaScript. The CanvasRenderingContext2D object is then obtained from this element, and it is this object that provides all the drawing capabilities. Common operations include drawing lines, rectangles, circles, arcs, and paths. Developers can also fill these shapes with solid colors, gradients, or patterns.

Furthermore, Canvas2D supports drawing text with various fonts, sizes, and alignments. Images can be drawn onto the canvas, and their pixels can be manipulated, enabling effects like pixel manipulation or image filtering. Transformations, such as translation, rotation, and scaling, can be applied to the drawing context, allowing for complex visual compositions. The Canvas2D API is widely used for creating visualizations, games, interactive graphics, and dynamic user interfaces within web browsers.
