File Operations

All file operations are supported by a file selector dialog box to select a file name.

File in the menu line offers the following file operations:  

• Open File...  
  Open the file selector box to select a file name. A new graph specification is read from the file selected, a layout calculated, followed by the graph being displayed.

• Reopen File (g)  
  This operation causes the file containing the current graph specification to be read again, the layout recalculated and the graph displayed again. It can also be invoked by pressing the g key.  

• VCG1.0 Save...  
  Open the file selector box to select a file name. The graph currently displayed is then written to the file selected along with some calculated layout parameters. Note: This is a legacy feature providing compatibility to VCG V.1.0. It may not work for graph specifications that contain any newer GDL features.

Graphs or parts of graphs can be exported to files in several formats for which many printer drivers are available. Exporting is done via the export dialog box.

• Print/Export Part...  
  A rectangular rubberband is used to select part of the graph currently shown in the display window. Selecting is done like this:
  • Press the left mouse button and hold it down: The rubberband appears.
  • Drag it over the area of the graph to be exported followed by releasing the mouse button.

  After selecting the area to be exported the export dialog box pops up.

  Hint: To facilitate selecting the part to be exported it is useful to shrink the graph to a size so that this part is entirely visible.

  Note: It is not possible to export parts of a graph if splines have been used for drawing the edges.

• Print/Export Graph...  
  The Export dialog is opened.
