By default elements in a PlantUML generated diagram have shadows.
To disable shadows we must set the skin parameter shadowing to the value false.
PlantUML will then not create shadows on elements.
In the following sample PlantUML definition we use the value false for the skin parameter shadowing:
The default colors of PlantUML use red and yellow to draw the diagram elements.
If we want our diagram to be in black, grey and white we can simply set skin parameter monochrome to true.
The generated graphical diagram will now have black, grey and white colors.
In the following sample PlantUML definition we set the diagram skin parameter monochrone to true:
Drawing diagrams with PlantUML is fun and easy. We use text to describe the diagram and the we get a graphical representation. Especially in combination with Asciidoctor with PlantUML integration we have a winning combination to write technical documentation. Because our text is transformed into a graphical format like PNG we don't have much influence on the layout. There are options to indicate positions of elements, but we can also use the length of lines to influence the position of elements.
In the following sample we have a PlantUML diagram description with standard lines.
We use two hyphens (--) to define a line:
