Reads layout information from xdot ASTs

Simple layout types

type pos = float * float

2D coordinates

type bounding_box = pos * pos

upper-left and bottom-right corners

Layout informations are parsed from xdot files (dot files with graphviz layout).

Each node or edge layout thus contains several lists of drawing operations.

See http://www.graphviz.org/doc/info/output.html#d:xdot to understand the details of the layout informations.

type node_layout = {

n_name : string;
(*
Dot label
*)
n_pos : pos;
(*
Center position
*)
n_bbox : bounding_box;
(*
Bounding box
*)
n_draw : XDotDraw.operation list;
(*
Shape drawing
*)
n_ldraw : XDotDraw.operation list;
(*
Label drawing
*)

}

Each node has at least a position and a bounding box.

type cluster_layout = {

c_pos : pos;
c_bbox : bounding_box;
c_draw : XDotDraw.operation list;
c_ldraw : XDotDraw.operation list;

}

type edge_layout = {

e_draw : XDotDraw.operation list;
(*
Shapes and curves
*)
e_ldraw : XDotDraw.operation list;
(*
Label drawing
*)
e_hdraw : XDotDraw.operation list;
(*
Head arrowhead drawing
*)
e_tdraw : XDotDraw.operation list;
(*
Tail arrowhead drawing
*)
e_hldraw : XDotDraw.operation list;
(*
Head label drawing
*)
e_tldraw : XDotDraw.operation list;
(*
Tail label drawing
*)

}

Parsing and reading XDot

exception ParseError of string

module Make (G : Graphviz.GraphWithDotAttrs) : sig ... end

Instantiates a module which creates graph layouts from xdot files

Converts and reads various layout informations

val bounding_box : (float * float) -> float -> float -> bounding_box

bounding_box pos w h converts a bounding box of center pos, width w and height h from a Dot file to a pair of corners (lower left and upper right) in the world coordinate system.

parameter pos
position of the center of the node

parameter w
width of the node

parameter h
height of the node

val read_bounding_box : string -> bounding_box

val read_node_layout : Dot_ast.node_id -> Dot_ast.attr list -> node_layout

Reads xdot layouts from the dot ast

val read_edge_layout : Dot_ast.attr list -> edge_layout

val read_cluster_layout : Dot_ast.attr list -> cluster_layout
