S209: and removing the display of the handwriting fitting handwriting, and displaying the screen updating information on the ink screen.
It can be understood that, when the handwriting drawing operation is performed, since the android-based third-party application needs to send screen updating information to the screen drawing synthesizer after the handwriting drawing operation is completed, a very large display time delay will be caused in the period of waiting for the completion of the handwriting drawing operation, in this embodiment, the handwriting input processing function of the handwriting display device self system is firstly utilized, the handwriting fitting handwriting is displayed on the ink screen, after the completion of the handwriting drawing operation is detected, the screen drawing synthetic layer is notified to remove the display of the constructed handwriting fitting handwriting after the pen lifting updating time delay corresponding to the third-party configuration information, the normal image display updating of the system is recovered, and the processing result of the handwriting drawing operation by the third-party application is displayed on the ink screen.
In the process of generating and displaying the handwriting fitting handwriting, the processing process of the third-party application is not influenced, the display of the final processing result of the third-party application is also not influenced, but when the final processing result of the third-party application is displayed, the track of the handwriting drawing operation is fitted first, the handwriting drawing operation of the user is responded more quickly, the perception of the user on display delay is reduced, and the user experience is optimized.
In the above, by responding to the handwriting drawing operation performed on the third-party application on the ink screen, determining the handwriting drawing information corresponding to the handwriting drawing operation, and displaying the handwriting fitting handwriting generated based on the handwriting drawing information on the ink screen, and when the handwriting drawing operation is completed, screen updating information provided by a third-party application is acquired, the handwriting fitting handwriting is removed, and the screen updating information is displayed on the ink screen, during the handwriting drawing operation, firstly displaying the handwriting fitting handwriting on the ink screen, updating the handwriting fitting handwriting into screen updating information after the handwriting drawing operation is finished, the corresponding drawing tracks are synchronously displayed for the user in the handwriting drawing operation process, the condition that the user experience is influenced due to too large display delay of screen updating information is reduced, the display effect of the electronic ink screen is effectively optimized, and the user experience is improved. The method can be applied to a global annotation scheme of the electronic book, and can solve the problem that usability is too poor due to too large delay of the conventional android electronic ink screen equipment when handwriting drawing and rendering are carried out according to a normal android input flow. Through the determination of a specific scene, when the handwriting drawing operation is transmitted to a third party application according to a normal flow, the screen drawing synthesizer utilizes the time slice to perform handwriting fitting and display, and after the third party application self result is rendered, an accurate result is displayed, so that the final display effect is accurate, the problems of low updating speed caused by the characteristics of the electronic ink screen and overlong waiting time from integral input to output caused by a normal input flow can be avoided.
