Offscreen Rendering
Offscreen Rendering
Offscreen rendering lets you obtain the content of a browser window in a bitmap, so it can be rendered anywhere, for example on a texture in a 3D scene. The offscreen rendering in Electron uses a similar approach than the Chromium Embedded Framework project.
Two modes of rendering can be used and only the dirty area is passed in the 'paint' event to be more efficient. The rendering can be stopped, continued and the frame rate can be set. The specified frame rate is a top limit value, when there is nothing happening on a webpage, no frames are generated. The maximum frame rate is 60, because above that there is no benefit, just performance loss.
Note: An offscreen window is always created as a Frameless Window.
