Embodiment Construction

[0030] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0031] Such as figure 1 As shown, a method for realizing font drawing based on the FreeType font engine includes:

[0032] Steps to initialize the FreeType engine library and load the freetype.lib font library;

[0033] Create the FT_Face handle of the font, read the object of the freetype.lib font library, and process the read object into a bitmap;

[0034] as well as

[0035] Render the bitmap into the texture buffer, and then write the steps in the map.

[0036] Preferably, the step of creating the FT_Face handle of the font, reading the object of the freetype.lib font library, and converting the read object into a bitmap specifically includes,

[0037] The s...

Abstract

The invention discloses a method for achieving font rendering based on a FreeType font engine. The method comprises the steps that a FreeType engine library is initialized, and a freetype.lib font library is loaded; the FT_Face handle of a font is established, an object of the freetype.lib font library is read, and the read object is processed and transformed into a bitmap; the bitmap is rendered into a texture cache, and then is written into a chartlet. The font is rendered onto a texture through the FreeType, and then is displayed through the texture chartlet. The purpose of displaying Chinese characters quickly and conveniently is achieved.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a method for realizing font drawing based on a FreeType font engine, that is, a method for rendering characters to textures and displaying them. Background technique [0002] At present, in software development, it is usually not necessary to consider the display of fonts. It is provided by the operating system as a basic function. However, with the development of computer systems, efficient, fast, and beautiful fonts have become a market demand, especially in electronic equipment. The application is closely related to people's life. In domestic online games, Chinese characters cover many languages ​​used in the game, but the graphics card in the game scene does not support Chinese characters. It needs to parse the fonts, and most engines provide font processing interfaces. . [0003] Many games use different methods to display fonts, but there is no unified regulation, but...
