基于ICU的复杂文本布局引擎设计与跨平台应用研究

Study on Design of CTL Based on ICU and Its Cross-platform Application

ICU复杂文本布局引擎与其他应用较为广泛的复杂文本布局引擎相比的一大长处是它的开放源代码。通过分析ICU源码,并以此为基础设计新的复杂文本的布局引擎。首先简要介绍了复杂文本布局引擎的一般原理,然后以复杂文字语言蒙古文为例,详细探讨了基于ICU的复杂文本布局引擎的设计思路和方法,最后对复杂文本布局引擎的跨平台应用进行了深入研究。

One of the strong points of ICU Complex Text Layout （CTL） engine is that its source is open. This paper analyzes ICU＇ s source code, and design new complex text layout engine based on it. It first introduces the mechanism of the complex text layout engine, then takes Mongolian as an example to illustrate how to design complex layout engine based on ICU, and last talks about the cross-platform application of ICU layout engine.
