Abstract
Systems and methods for rendering web content in a browser are described herein. An embodiment includes a web rendering engine in a rendering engine process to generate one or more requests to selectively redraw one or more regions of content retrieved by a browser process. A renderview then generates a bitmap based on the requests and content retrieved by the browser process. The bitmap may then be stored by the renderview in a shared memory area where it may be accessed by a renderview host in the browser process. The renderview host may then provide the bitmap to a backing store associated with a display device for display to a user. In another embodiment, the shared memory area between the browser process and the rendering engine process may be used to achieve efficient scrolling of a web page through rate limited rendering of content.
