Rendering Modes

PlantUml.Net can render in 2 modes, Local and Remote.

Remote Rendering (default)

Remote rendering mode uses the PlantUml hosted service to render diagrams.

Docker

You can also spin your own PlantUml server using docker.

docker run -d -p 8080:8080 plantuml/plantuml-server:jetty

Now you can use the remote rendering with http://localhost:8080 as url.

Local Rendering

Local rendering mode uses a local copy of PlantUml to render diagrams.

Requirements

Java

PlantUml

Download PlantUml. By default PlantUml.Net looks for plantuml.jar in the woring directory; you can specify an alternate location in PlantUmlSettings.

GraphViz Dot (optional)

GraphViz Dot is required for Local rendering mode of any diagram other than sequence.

Install GraphViz Dot You may need to set the GRAPHVIZ_DOT environment variable
