In what follows we show how to use BLAG for constructing drawings of trees.
If you want to construct a tree drawing with BLAG, simply do the
An example of tree constructed with the previous steps
is shown in the following figure.
- Construct the file "filename" containing your tree using the
GDT file format.
- Perform the commandline:
Where "conf" is a configuration file that allows to customize the
behaviour of BLAG. A full description of the cofiguration file syntax
In this case we suggest the following
content for "conf":
Number 9 corresponds to the TreeCenterSons algorithm. Alternatively, you
can use number 10, that is TreeCenterSubtree.
<ALGORITHM> 9 </ALGORITHM>
- At this point file "filename.exp" stores all the
information that is needed to draw your tree, according to the
simplified export format.
Note that another file is also created, called "filename.gdt".
It contains the same information in a format that is the internal
format of GDT and that is a little more complicated.
