.SH USING JGRAPH TO DRAW PICTURES
|
|
As hypercube.jgr and alb.jgr show, jgraph can be used as a postscript
|
|
preprocessor to make drawings. There are two advantages
|
|
using jgraph to draw pictures instead of using standard drawing tools like
|
|
-\fIxfig\fB,
|
|
-\fIfigtool\fB,
|
|

|
|
+\fIfigtool\fR,
|
|
or
|
|
-\fIidraw\fB.
|
|
+\fIidraw\fR.
|
|
The first is that with jgraph, you know exactly where strings, lines,
|
|
boxes, etc, will end up, because you plot them explicitly. The second
|
|
advantage is that for iterative drawings, with lots of patters, you
|
