PlantUML Pleasantness: Use Gradients In Diagrams

We have a lot of ways to customize our PlantUML diagrams. We can change the colors and we can even set gradients as color. A gradient has two colors and a direction. The direction of the gradient is set by the separator between the two colors. We can use the following separators to set the gradient direction:

  • /: direction top left to bottom right
  • \: direction bottom left to top right
  • |: direction left to right
  • -: direction top to bottom

In the following example PlantUML diagram definition we apply different gradient directions and different colors:

When we convert this PlantUML syntax to a PNG image we get the following result:
