新型花型准备系统绘图引擎的研究与实现

Research and implementation of new drawing engine of pattern preparation system

针对目前国外先进的电脑横机花型准备系统的不足,紧密结合打板工艺的生产设计实践,介绍了一种新型电脑横机花型准备系统绘图引擎的设计思路,并提出了一套基于面向对象和多图层概念的全新图形编辑系统的实现方案。通过建立灵活的类管理机制和采用高效的内存流压缩算法,解决了大数据量的位图处理,实现了针对本花型准备系统五个图层操作的快速绘图。

Considering the advantage and disadvantage of todays pattern preparation system of computerized flat knitting machine, combining production practice of the drawing process, the paper introduce a new drawing engine of pattern preparation system of computerized flat knitting machine and then bring up a new program for graphic editor system which based on object-oriented and multi-layer concept. By building flexible mechanism of class management and adopting a highly efficient memory-compression arithmetic, solve to dispose of the mass date BMP and realize quick drawing of the pattern preparation system.
