CorelDRAW环境下国界符号的尺寸改正与快速符号化

Size Correction and Quick Symbolization of National Boundary in CorelDRAW

由于国界符号结构的特殊性,CorelDRAW自身难以实现其快速符号化,且国界符号的设计尺寸与实际尺寸往往不一致。为此,在研究CorelDRAW环境下利用矩形箭头代替国界短线实现国界画法的基础上,通过多次转换实验,获得了国界符号的设计尺寸到实际尺寸的改正比值,同时借助VB.NET开发平台,利用CorelDRAW 15.0Type Library开发资源进行了二次开发,使国界符号的设计尺寸与实际尺寸达到了一致,实现了国界符号的准确绘制和快速符号化。

Because of the particularity of national boundary symbol,it＇s difficult to achieve quick symbolization in CorelDRAW,and the designed size and actual size of national boundary symbol are inconsistent.This paper uses rectangle arrowhead to draw national boundary instead of border short line,the correction values from designed size to actual size of national boundary symbol have been obtained by many transformation experiments.In addition,we use VB.NET and CorelDRAW 15.0 Type Library to make secondary development,procedurally achieves the consistency between designed size and actual size of national boundary symbol and makes it more accurate and faster when drawing national boundary symbol.
