虚线型测井曲线的矢量平滑画法

SMOOTHING METHOD FOR DRAWING LOG CURVES WITH DASHED LINE

为了解决用计算机绘制测井曲线时常出现的虚线型线条长短不均的问题 ,采用线性插值方法设计了通用的矢量绘图平滑画法逐点平滑画法。应用结果表明 ,此方法几何意义明确 ,算法清晰 ,时空复杂度低 ,平滑效果好 ,适用于任何向量绘图方式下用虚线绘制测井曲线 ,是一种平滑效果较好的实用画法。

It is difficult to keep the solid and void dash line in a constant proportional spacing when using dashed line to plot the log curves. Some methods to solve the above problem are given, and a universal smoothing plot method is designed with linear interpolation. The application examples demonstrate its availability and efficiency in different software developing environment for the use of vector plot mode.
