Problems solved by technology

[0005] However, in the process of implementing the present invention, the inventors have found that the above-mentioned solutions in the prior art have at least the following defects: first, when the system caches the layer composition operation for each layer, it takes a lot of time, therefore, Compositing operations will cause a delay of at least 10ms
Moreover, when the number of applications in the system is large, resulting in a large number of layers, the delay of the compositing operation may even reach more than 20ms
Secondly, copy the result obtained after the compositing operation to the display cache, so that when the display cache synchronizes the copied content to the display screen for display, the copy operation will cause a delay of at least 20ms
It can be seen that the handwriting input method in the prior art has a long delay and a slow display speed, and cannot display the handwriting input content in approximately real time

Embodiment 1

[0028] figure 1 A flow chart of a method for displaying handwritten input content provided by an embodiment of the present invention is shown. Such as figure 1 As shown, the method includes the following steps:

[0029] Step S110: Obtain handwriting input content input by the user.

[0030] Wherein, this step is executed whenever the handwritten input content input by the user is received. Specifically, the specific connotation of the handwritten input content can be flexibly defined by those skilled in the art. For example, the content input by the user through various applications and / or various handwriting input methods may be obtained as handwriting input content. For another example, only content input by the user through preset applications such as e-book applications may be obtained as handwritten input content, depending on actual business requirements. For example, an application that needs to increase the speed of handwriting input can be determined in advance a...

Embodiment 2

[0040] figure 2 A flow chart of a method for displaying handwriting input content provided by another embodiment of the present invention is shown. Such as figure 2 As shown, the method includes the following steps:

[0041] Step S210: Whenever user input content is received, determine whether the application corresponding to the user input content is a preset application; if so, determine that the user input content is handwriting input content.

[0042] In this embodiment, the application that needs to increase the handwriting input speed is determined in advance as a preset application, and the operations in the subsequent steps are only performed on the content input through the preset application. In this embodiment, the preset application mainly refers to an e-book application.

[0043] Specifically, this step can be implemented through at least one of the following two implementations: In the first implementation, the application identification contained in the use...

Embodiment 3

[0063] An embodiment of the present application provides a non-volatile computer storage medium, the computer storage medium stores at least one executable instruction, and the computer executable instruction can execute the method for displaying handwritten input content in any of the above method embodiments.

[0064] Specifically, the executable instruction can be used to make the processor perform the following operations:

[0065] Obtain the handwritten input content entered by the user;

[0066] Get the image data stored in the display cache;

[0067] The handwriting input content is added to the image data stored in the display buffer to obtain modified image data, which is used for the display buffer to synchronize the modified image data to the display screen.

[0068] In an optional manner, the display content on the display screen and the image data stored in the display buffer are synchronized with each other, and the image data stored in the display buffer is syn...

Abstract

The invention discloses a handwritten input content display method, an electronic device and a computer storage medium. The method includes: obtaining a handwritten input content input by a user; Acquiring image data stored in the display buffer; adding The handwriting input content to the image data stored in the display buffer to obtain the modified image data for the display buffer to synchronize the modified image data to the display screen. The method directly draws the handwriting input content onto the image data stored in the display buffer without performing picture synthesis and copying operations via the system buffer, thereby greatly improving the display speed.

Description

[0001] The patent application for the present invention is a divisional application. The application number of the original case is: 201711431191.7, the application date is: December 26, 2017, and the title of the invention is: display method of handwritten input content, electronic equipment and computer storage medium. technical field [0002] The invention relates to the field of computers, in particular to a display method for handwritten input content, electronic equipment and a computer storage medium. Background technique [0003] At present, with the increasing popularity of touch-screen displays, more and more users are accustomed to editing content through handwriting input. In order to display the handwriting input content, the following methods are usually used in the prior art: [0004] For the convenience of display, the layers corresponding to all drawing operations are stored in a system area (also called system cache). Copy the result of the layer composit...
