![绘制内部节点以获取 BPMN 网关形状](https://linux22.com/image/246238/%E7%BB%98%E5%88%B6%E5%86%85%E9%83%A8%E8%8A%82%E7%82%B9%E4%BB%A5%E8%8E%B7%E5%8F%96%20BPMN%20%E7%BD%91%E5%85%B3%E5%BD%A2%E7%8A%B6.png)
我正在尝试从 BPMN 获取AND
网关XOR
,如下所示http://www.omg.org/bpmn/Samples/Elements/Gateways.GIF
作为起点,我找到了这个样式文件https://github.com/sbadia/gdeploy/blob/master/francegrilles/tikz-bpmn.sty但为了在网关中得到加号和 x,我必须将它们设置为文本。这看起来一点也不好看……我该如何为网关绘制一个粗“加号”,AND
并为添加相同的旋转 45° 的份额XOR
?“粗”的意思是它比形状的边框厚得多。还要注意,加号和 x 实际上都没有到达周围形状的边框。
答案1
我基于菱形创建了三种新形状。如果您需要缩放这些形状,并且需要缩放圆形、十字形、+ 等...,那么选择另一种方式在菱形内部进行绘制会很有趣。只有 EB 定义明确,对于所有其他形状,您需要绘制路径并填充它。但这需要大量工作。
