I found example like this:
@startuml
rectangle a [
this is 1st liine
<img:image.png>
this is second line
]
@enduml
This simply renders a rectangle with text and an image. You cannot do that with
rectanble b {...}
I'm wondering if that's some side effect (not a feature) or there is some explanation :)
ps. I'm looking for ways of embedding colorful icons into PlantUML components such rectangle etc. Btw. I found I can do this with:
card "test \n <img:icon.png> \n test"
