node layout

  • Icons
    • when you specify 'iconfile' then 'bordercolor' will implicitly be set to 'white' and 'label' will be set to an empty string.
  • Node Geometry
    • when calling #wgraph you can set two scale factors, one for the image and one for the corresponding thumb image.
    • these scale factors can be understood as "dots per inch" measures.
    • scaling does not work with bitmap images
  • Colors
    • there are 31 pre-defined names
    • you can use #000000 .. #ffffff notation
