Co-Word中图文混排的文档一致性研究*

近年来，人们设计各类算法来实现协同编辑中的文本一致性维护，而关于Word中图文混排的研究相对较少。本文提出，对Word中的图片对象和文字对象重新建模、分别存储，以行作为单位设置文档中对象的摆放位置，并通过算法消解各类图片对象和文字对象间的位置冲突，实现图文混排与各站点的一致性。本文在Co-Word原型系统中增加了图文混排支持，并通过实例分析来讨论策略的执行流程。

Consistency Maintenance during the Mixed Editing Process of Graphs and Texts in Co-Word System

In recent years, researchers introduced many algorithms to achieve consistency maintenance in text editing fields. However, the research of the mixed editing process of graph and text in Word got little attention. This paper proposes a new document model consisting of graph and text object in Word, which divides the storage space into graphs and texts, and adopts the line as the unit to present the position of the objects. Besides, a consistency maintenance algorithm is designed to solve the conflicts between texts and graphs with different attributes. The paper improves the Co-Word prototype by adding the support of the mixed editing of texts and graphs, and gives case analysis to demonstrate the work flow of the whole strategy.
