在VxWorks系统中使用TrueType字库

Using TrueType font in VxWorks system

为了得到高质量而且灵活(包括对字形的各种变形操作)的字符显示,同时又能实现所见即所得(WYSIWYG)的打印,传统的使用点阵字库的方法已经不能满足要求.有一个很好的方法———使用TrueType字库,可以同时解决以上两个问题.介绍了TrueType技术的基本原理及在VxWorks系统中如何通过FreeType应用TrueType字库.在实际应用中,该技术很好地解决了上述问题.但这种技术也可以很容易地移植到很多其他系统中,如Linux.

In order to obtain high quality and flexible (all kinds of transformations) characters display and What You See Is What You Get (WYSIWYG) printing, the traditional way of Using Dot-Matrix Font can no longer satisfy our needs. Here is a good solution that can solve both the problems: Using TrueType font. The basic knowledge of TrueType was introduced as well as how to use it in VxWorks system with the help of FreeType. It well solved the problems above. This technology can also be used in many other systems like Linux.
