Problems solved by technology

[0005] The above method of displaying text has many problems. One is that image files take up a lot of memory. If there are a lot of text to be displayed and the memory is too small, the program may not run efficiently or even load.
Second, it is impossible to display previously unknown text, such as user input, text obtained from the network, etc.

Embodiment Construction

[0025] Such as figure 1 As shown, it is a flowchart of a method for displaying text in an embodiment. The method comprises the steps of:

[0026] S10: Obtain the dot matrix information of the text to be displayed according to the built-in font file storing the dot matrix information of the text and the general character table storing the position information of the text in the font file.

[0027] The dot matrix information of the text records the state information of the pixels in the display area when the text is formed. The state information indicates that there are two states of strokes or no strokes on the pixel, so the state information of each pixel can be represented by a binary bit (bit ) to store, and use "0" and "1" to represent two different states respectively. For example, for a text with a size of 16*16 pixels, 256 bits are required to store the dot matrix information of the text. Such as figure 2 Shown is a schematic diagram of using dot matrix information ...

Abstract

The utility model relates to a method for displaying characters, which belongs to the technical field of computers, and comprises the steps as follows: lattice information of characters to be displayed is obtained according to a typeface file used for keeping lattice information of characters in a program and a whole character table keeping the position information of the characters in the typeface file; and the characters are displayed according to the lattice information of the characters to be displayed. Besides, the invention also relates to a system for displaying characters according to the method. In the method and the system, a program developer can use self-defined typefaces through using the built-in typeface file, and the flexibility on the aspect of using different styles of typefaces is improved. Moreover, compared with the characters displayed through pictures, displaying the characters by using the lattice information of the characters can greatly reduce a running memory, and can display the unknown typefaces in advance in real time according to the typeface file.

Description

【Technical field】 [0001] The invention relates to the field of computers, in particular to a method and system for displaying text. 【Background technique】 [0002] In some small devices, especially in handheld mobile terminals, J2ME is used as the application platform. J2ME (Java 2 Micro Edition) is a java application platform widely used in small devices launched by SUN Company. The application program based on this can greatly expand the functions of handheld mobile terminals. [0003] With the increase of application programs, personalized appearance and operation interface also become important, and one of the more important aspects is the use of personalized fonts. [0004] Traditional J2ME applications can only use the system fonts provided by the terminal device during development. When displaying text, the fonts of the terminal system are used to make picture files, and the text is displayed by loading pictures when the application is running. [0005] The above m...
