Article Introduction：You can save the animation by recording HTML5canvas animation and encoding it into a video file. First, use the MediaRecorder API to record the canvas output, obtain the stream through canvas.captureStream(), create a MediaRecorder instance and collect data blocks, and finally generate a downloadable WebM video. Secondly, if you need higher quality or specific formats, you can export frame images (PNG/JPEG) and synthesize videos through tools such as FFmpeg. In addition, pay attention to performance and file size, appropriately limit frame rate, select compression formats, and consider the backend processing of long videos. The two methods have their own advantages and disadvantages, and choose according to your needs.

Article Introduction：Core points The HTML5 canvas element allows native integration of multimedia content, including line drawings, image files, and animations, into web pages, and can be used to create sliding puzzle games. The canvas drawing is performed through a context that is initialized by the JavaScript function getContext(). The drawImage() function in JavaScript is used to display images on canvas, and different parameter options allow resizing images and extracting image parts. The game logic of the sliding puzzle involves creating a two-dimensional array to represent the board. Each element is an object with x and y coordinates that define its position in the puzzle grid. checkerboard

Article Introduction：Using H5's WebGL to achieve high-performance 2D graphics rendering is because WebGL is based on GPU and has hardware acceleration capabilities. It is more suitable for handling large amounts of graphics drawing and complex animation than Canvas2D. 1.WebGL is a browser interface based on OpenGLES, which runs on the GPU to improve graphics processing efficiency; 2. HTML5 provides the canvas container to carry WebGL content, achieving high-performance rendering without plug-ins; 3. Compared with Canvas2D, WebGL supports hardware acceleration and has stronger performance, especially suitable for frequent redrawing or graphics-intensive scenarios; 4. Developers can realize 2D graphics by obtaining WebGL context, writing shader code, creating buffers, setting projection matrix, etc.
