User's Guide to the Graphics Editor

The Tycho graphics editor is still in highly preliminary form. It is currently used as a base class for more specialized editors like the graph display widgets. The features it currently provides are described below.

Titles

Support for title, subtitle, author, version and copyright header information. The idea here is to provide a common look for titles across a wide variety of graphical display and edit widgets in Tycho that will need titles. The "Title" command in the "Edit" menu invokes a dialog that facilitates entering such titles. This dialog lists only title types that do not already exist. To edit an existing title type, use the "Edit Item" command in the "Edit" menu.

What goes in the version title depends on the version control system you will use. If you use SCCS, then the following will work well:

	Version: %W% %G%
	
The SCCS system will translate this when the file is checked in to, for example,
	Version: @(#)filename	1.2  12/13/96
	
Similarly, the copyright line used at Berkeley looks like this:
	Copyright (c) 1995-%Q%, The Regents of the University of California.
	
The SCCS version control system translates this to
	Copyright (c) 1995-1996, The Regents of the University of California.
	

Printing

The contents of the canvas in a graphical widget can be converted to postscript and sent to a printer. The "Print" command in the "File" menu opens a dialog box that controls various parameters of this process.

Exporting

The contents of the canvas in a graphical widget can be converted to a number of file formats, including encapsulated postscript GIF, and XWD. Currently, the latter two work on Unix installations only. The "Export" command in the "File" menu opens a dialog box that controls various parameters of this process.
