Wgraph:Tutorial node layout

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
