Problems solved by technology

[0005] Since the current technology is based on the API provided by the GUI to realize the text display, and the realization of the GUI needs to go through multiple layers of function calls, so the processing efficiency is low; It is executed sequentially in the form of a single task. When the display content is large, the speed of displaying fonts is relatively slow

Embodiment Construction

[0013] Embodiments of the present invention provide a three-dimensional font display method and a related device for parallel font display processing using OpenGL ES.

[0014] see figure 1 , an embodiment of the three-dimensional font display method in the embodiment of the present invention includes:

[0015] 101. Create a foreground process and a background process;

[0016] When font display is required, the three-dimensional font display device simultaneously creates a foreground process and a background process; the foreground process is used to obtain input text information, and initializes the open graphics library OpenGL ES of the embedded system; the background process is used to perform font library initialization, and perform corresponding operations according to the instructions of the foreground process.

[0017] Creating two processes for font display at the same time can reasonably share the load of the functional modules, so that the setting operation of the ...

Abstract

The embodiment of the invention discloses a method and related device for displaying a three-dimensional (3D) font, which are used for font display parallel processing by utilizing an OpenGL ES (open graphics library for embedded systems). The method comprises the following steps: a 3D font display device establishes a foreground process and a background process; the 3D font display device initializes the OpenGL ES of an embedded system by the foreground process; the 3D font display device initializes a font library by the background process; and the 3D font display device renders the input text messages through data interaction between the foreground process and the background process by utilizing the OpenGL ES. In addition, the embodiment of the invention further provides the related device for implementing the method.

Description

technical field [0001] The invention relates to the field of embedded graphics display, in particular to a three-dimensional font display method and a related device. Background technique [0002] Font display technology is an important technology in the field of electronic display devices at present. The display of fonts needs to process text information such as font type, text code, and text size, and then generate text images based on these text information; text images are font outlines generated based on vector data representing the shape of text. Specifically, when the display device displays a character image, the font outline to be displayed is filled with color using the vector data of the font outline, thereby generating a character image. [0003] With the continuous development of various portable devices, the application of font display technology in portable devices has become more and more important. How to use embedded technology to make font display effecti...
