Overview
The Canvas API provides a means for drawing graphics via JavaScript and the HTML <canvas> element. Among other things, it can be used for animation, game graphics, data visualization, photo manipulation, and real-time video processing.
Key Features
- Immediate Mode: Graphics are drawn directly to the screen and not stored in a scene graph.
- 2D Context: Provides methods for drawing paths, boxes, circles, text, and adding images.
- Pixel Manipulation: Allows for direct access to the pixel data of the canvas.
- Performance: Highly efficient for rendering large numbers of objects or complex animations.
Use Cases
- Simple 2D games.
- Dynamic charts and graphs (e.g., Chart.js).
- Image filters and editors.
