图元文件信息的存取与在工程中的应用

Accessing and application of information about metafile in project

提出一种采用CorelDRAW预先绘出图元文件,利用开发的软件取出其中的图元属性存入数据库,然后利用API函数绘图的方法,该方法提高了庞杂图形界面的制作效率和程序运行的速度,并在某国际机场助航灯光综合监控系统的界面设计中得到成功应用,同时具有广泛的应用价值.

This paper puts forward the method that draws the metafile beforehand by Corel DRAW, using the software developed to obtain the meta properties, saves them in database and adopts API to draw into the form. The efficiency and the speed were surely improved by using this method. This method has been applied in the interface design of assistant flight light in some airport monitoring system successfully and may have a broad application future.
