The invention provides an Electron master screen optimization method based on polymorphic rendering and state awareness, and is applied to the technical field of data processing. According to the method, aiming at an Electron advertisement screen application, a window focus, a power supply state and user interaction are monitored through BrowserWindows API and Node.jPowerMonitor, and three playing states, namely an active playing state, a low-frequency playing state and a background playing state, are judged. Rendering modes are dynamically switched according to the states, GPU acceleration is + 60 fps high frame rate in the active state, CPU software rendering is + 15 fps low frame rate in the low frequency state, and off-screen rendering is conducted on cached frame data in the background state. And the local redrawing is realized by combining the Offscene Canvas and the WebWorker, so that the invalid calculation is reduced. Resources such as DOM nodes and GPU memories are actively recycled in the background state, quick recovery is achieved after focus obtaining, users do not perceive the whole process, resource occupation and energy consumption are greatly reduced, and operation stability is improved.

Vector format based computer graphics tools have become very powerful tools allowing artists, designers etc. to mimic many artistic styles, exploit automated techniques, etc. and across different simulated physical media and digital media. However, hand-drawing and sketching in vector format graphics is unnatural and a user's strokes rendered by software are generally unnatural and appear artificial. In contrast to today's hand-drawing and sketching which requires significant training of and understanding by the user of complex vector graphics methods embodiments of the invention lower the barrier to accessing computer graphics applications for users in respect of making hand-drawing or sketching easier to perform. Accordingly, the inventors have established a direct vector-based hand-drawing / sketching entry format supporting any input methodology.
