PSTricks 选项之间的干扰

Question

我正在建造一栋建筑来解释非对称加密方案给我的学生。我用它pst-sigsys来设计框图，并pstricks-add画出关键部分：

我在设计钥匙时遇到了问题，但我已经收到了答案（见我的问题）。

问题是，我现在有pst-sigsys 圆角选项以及键的实际绘制。

我想要的钥匙是多于框架（不像图片中那样）。但是，在代码中，如果我将它们放在框架后面（参见 MWE），该RoundCorners选项会修改密钥。M. Voß 已经提出了部分解决方案，但它并没有完全发挥作用，所以我发布了一个新问题。

以下是导致这种情况发生的 MWE：

运行后，关键点与实际绘图不同。我查看了文档，并重置了:psy-sigsys中包含的所有选项，但显然这还不够……RoundCornerslinearc=0, framearc=0, framesep=0

Answer 1

使用或或按住\psset{RoundCorners,...}本地：\bgroup ... \egroup{...}\begingroup ... \endgroup
