Global Parameters

The global parameter section consists of 7 lines (with an arbitrary number of inter-mixed comment-lines).

1. version line
   The version line specifies the version of of the gw-format. It consists of the string GraphWin followed by a floating-point number (1.4 for the current version of GraphWin).

2. window parameters
   scaling wxmin wymin wxmax wymax
   This line consists of 5 floating-point numbers specifiying the scaling, minimal/maximal x- and y-coordinates of the window (see the window class of LEDA).

3. node label font
   type size
   This line defines the font used for node labels. The type value of of type int. Possible values (see gw_font_type) are
   0 ( roman_font)
   1 ( bold_font)
   2 ( italic_font)
   3 ( fixed_font). The size value is of type int and defines the size of the font in points.

4. edge label font
   type size as above, but defines the font used for edge labels.

5. node index format
   format
   This line contains a printf-like format string used for constructing the index label of nodes (e.g. %d).

6. edge index format
   format
   This line contains a printf-like format string used for constructing the index label of edges (e.g. %d).

7. multi-edge distance
   dist
   This line contains a floating-point parameter dist that defines the distance used to draw parallel edges.

We close the description of the global parameter section with an example.
