Backgroundcolor transparent doesn't work anymore

Question

I updated my plantuml version yesterday and I realized that the " skinparam BackgroundColor transparent" doesn't work anymore. (in my previous version, it worked well)

"

@startuml
skinparam BackgroundColor transparent

Bob -> Alice : hello
@enduml

"

background is grey and plantuml is always in white.

This feature is removed?

Answer 1

This is a regression. We are actually working on improving transparent/opacity support.

Right now, you can turn about this issue with :

@startuml
skinparam BackgroundColor #00000000
Bob -> Alice : hello
@enduml

We are going to fix it anyway soon.

Sorry about that!

We've just fixed this in last beta http://beta.plantuml.net/plantuml.jar and on the online server.

We are currently extending opacity/transparent support. Even if we pay a lot of attention on regression, maybe you'll find some other issue so please post here if you do !

Thanks!

Hello,

Maybe you'll find some other issue so please post here if you do !

Just FYI, for png output:

For some elements (sequence, usecase, deployement), if we have got only one element, that is KO:

 

But for only one state, mindmap and wbs that is OK:

If it can add some test cases, for help,

Regards,
