PlantUML Class 图 - field/method 在图例中的可见性

PlantUML Class Diagram - field/method visibility in legend

是否可以使用真实图标在图例中找到 class 图表的 field/method 可见性标签?

即在下图 table 中获取真正的图标

@startuml
class Dummy {
-field1
#field2
~method1()
+method2()
}

legend
|= field |= method |=  |
|  -     |   -     | private |
|  #     |   #     | protected |
|  ~     |   ~     | package private |
|  +     |   +     | public |

endlegend

我尝试过但没有成功的事情:

这很好(对我来说肯定足够好了):

@startuml
class Dummy {
-field1
#field2
~method1()
+method2()
}

skinparam legendBackgroundColor #ffffff
legend

|= field |= method |=  |
