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 section leda-format).

x-coordinate
an attribute of type double defining the x-coordinate of the center of the node.

y-coordinate
an attribute of type double defining the y-coordinate of the center of the node.

shape
an attribute of type int defining the shape of the node. Possible values are (see gw_node_shape of GraphWin)
0 ( circle_node)
1 ( ellipse_node)
2 ( square_node)
3 ( rectangle_node.

border color
an attribute of type int defining the color used to draw the boundary line of the node. Possible values are (see the LEDA color type)
-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).

border width
an attribute of type double defining the width of the border line of the node.

radius1
an attribute of type double defining the horizontal radius of the node

radius2
an attribute of type double defining the vertical radius of the node

color
an attribute of type int defining the color used to fill the interior of the node. See the LEDA color type for possible values.

label type
an attribute of type int specifying the label type. Possible values (see gw_label_type of GraphWin) are
0 ( no_label)
1 ( user_label)
2 ( data_label)
3 ( index_label).

label color
an attribute of type int defining the color used to draw the label of the node. See the LEDA color type for possible values.

label position
an attribute of type int defining the label position. Possible values (see gw_position of GraphWin) 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).

user label
an attribute of type string defining the user label of the node.

We close this section with an example of a node attribute line that 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.
