Problems solved by technology

[0004] 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

[0027] figure 1 It shows a flowchart of a method for displaying handwriting input content provided by an embodiment of the present invention. Such as figure 1 As shown, the method includes the following steps:

[0028] Step S110: Obtain the handwritten input content input by the user.

[0029] Wherein, whenever the handwriting input content input by the user is received, this step is executed. 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 can be acquired as handwriting input content. For another example, it is also possible to obtain only the content input by the user through a preset application such as an e-book application as handwriting input content, depending on actual business requirements. For example, an application that needs to increase the speed of handwriting input may be deter...

Embodiment 2

[0039] figure 2 It shows a flowchart of a method for displaying handwritten input content provided by another embodiment of the present invention. Such as figure 2 As shown, the method includes the following steps:

[0040] Step S210: Whenever the user input content is received, it is determined whether the application corresponding to the user input content is a preset application; if so, it is determined that the user input content is handwritten input content.

[0041] In this embodiment, an application that needs to increase the speed of handwriting input is determined in advance as a preset application, and operations in the subsequent steps are performed only for content input through the preset application. In this embodiment, the preset application mainly refers to an e-book application.

[0042] Specifically, this step can be implemented by at least one of the following two implementation manners: In the first implementation manner, the application identifier contained in...

Embodiment 3

[0062] An embodiment of the present application provides a non-volatile computer storage medium that stores at least one executable instruction, and the computer executable instruction can execute the handwriting input content display method in any of the foregoing method embodiments.

[0063] The executable instructions may be specifically used to cause the processor to perform the following operations:

[0064] Obtain the handwriting input input by the user;

[0065] Modify the stored image data in the display buffer according to the content of the handwriting input, so that the display buffer can synchronize the modified image data to the display screen;

[0066] Draw the handwriting input content in a custom layer located above each unsynthesized layer in the system cache, so that the system cache can perform layer synthesis for each unsynthesized layer and the custom layer Operation to update the image data stored in the display buffer according to the operation result.

[0067] I...

Abstract

The invention discloses a handwriting input content display method, an electronic device and a computer storage medium. The method comprises the steps that handwriting input content input by a user isobtained; stored image data in display cache is revised according to the handwriting input content, so that the revised image data is synchronized to a display screen by the display cache; the handwriting input content is drawn in a custom layer located in system cache and above each non-synthetic layer, so that layer synthesis operation is executed by the system cache aiming at each non-synthetic layer and the custom layer, and the stored image data in the display cache is updated according to operation resulTS. According to the method, the handwriting input content is directly drawn to thestored image data in the display cache, execution of image synthesis and replication operation does not need to perform via the system cache, and therefore display speed is significantly improved.

Description

Technical field [0001] The present invention relates to the field of computers, in particular to a method for displaying handwritten input content, electronic equipment and computer storage media. Background technique [0002] At present, with the increasing popularity of touch screens, more and more users are accustomed to editing content through handwriting input. In order to display the content of handwritten input, the following methods are usually adopted in the prior art: [0003] In order to facilitate the display, the layers corresponding to all drawing operations are saved in a system area (also called the system cache). After all the drawing operations are completed, the layer composition operation is performed on each layer saved in the system cache, and Copy the result of the layer composition operation to the display buffer (also called the frame buffer) for the display buffer to synchronize the copied content to the display screen for display. Among them, because th...
