In the example:
@startuml
[i]
component C {
portin p1
portin p2
portin p3
portout po1
portout po2
portout po3
component c1
}
[o]
@enduml
Portin is on the TOP, portout is at the BOTTOM;
How can change the position of portin / portout? For example, make the portin at the LEFT, and portout at the RIGHT?
