When we generate a PNG version of our PlantUML definition the original definition is stored in the PNG image. We can extract the definition using the command line option -metadata. We need to provide the PNG file and in the output we see the original PlantUML definition.
The following PNG image (activity.png) is created with PlantUML:
Next we run PlantUML from the command line using the option -metadata:
$ java -jar plantuml.jar -metadata activity.png ------------------------ activity.png @startuml ' Make a dashed line, alternative syntax for ..> (*) -[dashed]-> "Write outline" ' Make line bold and use color code "Write outline" -[bold,#008000]-> "Find example" ' Only change the color "Find example" -[#ff00ff]-> "Write blog" ' Order of line style and color can be reversed "Write blog" -[#6666ff,dashed]-> "Publish" ' Use dotted line style "Publish" -[dotted]-> (*) @enduml PlantUML version 8051(Thu Dec 01 18:52:05 CET 2016) (GPL source distribution) Java Runtime: Java(TM) SE Runtime Environment JVM: Java HotSpot(TM) 64-Bit Server VM Java Version: 1.8.0_112-b16 Operating System: Mac OS X OS Version: 10.12.1 Default Encoding: UTF-8 Language: en Country: US ------------------------ $
At the top we see the section @startuml..@enduml with the PlantUML syntax that was used to generate the PNG image.
Written with PlantUML 8051.
