可惜只能在1X1的方格绘制，不能像源泉那样的 根据X Y间距生成自定义填充，希望大神们优化！！！！
感谢分享，希望有高手改进 感谢分享，希望有高手改进 感谢分享，希望有高手改进 英文的注释和说明看着不舒服！改成了中文 大家共同努力争取早日将填充制作源码化 源泉的mkpat是免费的，还折腾重复造轮子有啥意义？写代码学习制作PAT的技术？学会了也没啥用武之地。 感谢源泉10多年陪伴! kozmosovia 发表于 2024-6-25 16:44
源泉的mkpat是免费的，还折腾重复造轮子有啥意义？写代码学习制作PAT的技术？学会了也没啥用武之地。
有源码可以学习或则修改不是更好吗 关键是主轴垂直偏差与水平偏差的比值不能太小，否则不能填充
