Abstract

The invention provides a font rendering device and a terminal, and the device comprises an information processing unit which is located in a central processing unit of the terminal and is used for processing a color font file into a font bitmap and color attribute information; a first rendering unit which is located in a graphic processor of the terminal, connected with the information processingunit and used for rendering the font bitmap according to the color attribute information. According to the invention, the font bitmap is rendered through the graphic processor; the diversified and personalized requirements of fonts during information interaction are met, the rendering speed is greatly increased, the problem of unsmooth operation caused by the fact that low-performance terminal equipment independently utilizes a central processing unit to render color characters is solved, the consumption of system resources is reduced, the rendering process is smoother and unlagged, and the user experience is improved.

Description

technical field [0001] The present invention relates to the fields of computer information processing technology and text information processing technology, in particular, to a font rendering device and a terminal. Background technique [0002] No matter on mobile devices or other computer devices, font files exist in standard formats, such as TTF and OTF formats, etc. System fonts can only be displayed in black, which does not support the diversity and personalization of information interaction very well. Relatively dull. At present, the technologies for rendering fonts into colors in the market are basically processed in the CPU. Due to the large amount of calculation, they are not suitable for use on low-performance terminal devices, and the color font files that this type of font color rendering technology is based on are also A custom format cannot be installed according to the font installation interface of existing computer equipment.
