GraphWin File Format - Node Attributes

Node Attributes

The node attribute section contains for each node of the graph a line consisting of the following attributes (separated by blanks). More precisely, the i-th line in this section defines the attributes of the i-th node of the graph (see native graph fileformat).

1. x-Coordinate: an attribute of type double defining the x-coordinate of the center of the node.
2. y-Coordinate: an attribute of type double defining the y-coordinate of the center of the node.
3. Shape: an attribute of type int defining the shape of the node. Possible values are
   • 0 (circle_node)
   • 1 (ellipse_node)
   • 2 (square_node)
   • 3 (rectangle_node)
4. Border Color: an attribute of type int defining the color used to draw the boundary line of the node. Possible values are

   -1 (invisible) 0 (black) 1 (white) 2 (red) 3 (green) 4 (blue)

   5 (yellow) 6 (violet) 7 (orange) 8 (cyan) 9 (brown) 10 (pink)

   11 (green2) 12 (blue2) 13 (grey1) 14 (grey2) 15 (grey3) 16 (ivory)

5. Border Width: an attribute of type double defining the width of the border line of the node.
6. Radius1: an attribute of type double defining the horizontal radius of the node
7. Radius2: an attribute of type double defining the vertical radius of the node
8. Color: an attribute of type int defining the color used to fill the interior of the node. See color for possible values.
9. Label Type: an attribute of type int specifying the label type. Possible values are
   • 0 ( no_label)
   • 1 ( user_label)
   • 2 ( data_label)
   • 3 ( index_label)
10. Label Color: an attribute of type int defining the color used to draw the label of the node. See color for possible values.
11. Label Position: an attribute of type int defining the label position. Possible values are
    • 0 ( central_pos)
    • 1 ( northwest_pos)
    • 2 ( north_pos)
    • 3 ( northeast_pos)
    • 4 ( east_pos)
    • 5 ( southeast_pos)
    • 6 ( south_pos)
    • 7 ( southwest_pos)
    • 8 ( west_pos).
12. User Label: an attribute of type string defining the user label of the node.

Example for Node Attribute Line: Describes a circle node at position (189,260) with border color black, border width 0.5, horizontal and vertical radius 12, interior color ivory, label type index_label, label position east_pos, and an empty user label.

# x y shape b-clr b-width radius1 radius2 clr l-type l-clr l-pos l-str 
189.0 260.0 0 1 0.5 12.0 12.0 16 3 -1 4
