Unable to convert Ditaa diagram to png

Question

Hi,

This is my version of Plantuml:

PlantUML version 1.2025.4 (Sat Jun 28 13:09:25 CEST 2025)

I'm trying to get a png from the following Ditaa diagram:

@startditaa
+-----------------+
| Things to do    |
| cGRE            |
| o Cut the grass |
| o Buy jam       |
| o Fix car       |
| o Make website  |
+-----------------+
@endditaa 

using plantuml.jar with this command:

java -jar /opt/plantuml/plantuml.jar mydiagram.puml

but I'm always getting this response:

Warning: no image in mydiagram.puml
No diagram found

I can however create png's from class diagrams (@startuml/@enduml) without problems.

Are Ditaa diagrams maybe not supported by this version of Plantuml? Thanks for your help,

Daniel.

Answer 1

The diagram works ok on planttext, which runs version 1.2025.10 (Nov 04).

Try upgrading?

That was probably the reason, but I finally converted the graph using the ditaa jar file, instead of plantuml.

Thanks a lot for your help.
