Export

The file menu contains a submenu with a number of different file formats that it is possible to export the graph to. The submenu is under the menu item called Export to.... Bellow are the different file formats described with referenses to webpages where it is possible to find more information.

Graphviz dot-file format

This format can be used with the Graphviz tools produced in the Graphviz project. The Graphviz tools can create images of graphs from simple graph descriptions. The generated file is a description of a undirected graph created from the current graph. See the Graphviz documentation for information of how to change the files and configure the output. Bellow is an example of a command that produces a PNG-image file with a graph drawn from the description in the test.dot file:
neato test.dot -Tpng > test.png

GraphML

GraphML is an XML based file format for describing all types of graph structures. Among other things it has support for both undirected and directed graphs. The generated file is a description of an undirected graph.

Graph Modeling Language (GML)

GML was created to make a universal graph file format that could be used in all types of graph programs. It is possible to attach all kind of data to the graph objects.

File format compatible with Mathematica Combinatorica software

This file format is a simple neighbour list with position information for vertices. It can be opened with the Mathematica software.

Each row in the file format represents a vertex. The first number on each line is a vertex identification. The two floating point number next on the line is the horizontal and vertical coordinates of the vertex. The numbers coming after that is the identifications of the vertices that are neighbours to the vertex.

Neighbour list

The files exported by this exporter are exactly the same as files that are exported by the Mathematica exporter except that they do not contain vertex position information.

JPEG image file format

When you export to a JPEG (Joint Photographic Experts Group) image the graph is exported exactly as it looks like in the graph window except that the selection is cleared. This means that if you zoom in the graph the exported image will be bigger. The image exported is the same size as the least bounding rectangle of all vertices plus an empty border with 5 pixels.

PNG image file format

The PNG (Portable Network Graphics) export export is similar to the JPEG export but produces a PNG image.

EPS image file format

The EPS (Encapsulated PostScript) image files produced by this exporter uses vector graphics which makes the images scalable. It is a very popular file format for images included in e.g. scientific reports.
