The provided source details Chrome's rendering pipeline, a multi-stage process that transforms web content into on-screen pixels. It begins with parsing HTML to build the Document Object Model (DOM) tree and processing CSS styles to compute how each element should look. Next, the layout stage calculates the precise geometric position and size for every element, forming a layout tree. Subsequently, the painting stage records abstract drawing operations into a display list, which the rasterization stage then converts into actual pixel bitmaps, often utilizing the GPU for acceleration. Finally, the compositing stage, managed by a dedicated thread, organizes these pixel data into layers and tiles, assembling them into a final CompositorFrame that the Viz display compositor ultimately uses to present the complete image to the user.
