\Treestyle{<style option>}
, where <style option>
contains all the parameter settings the user might want
to change.
Normally, the command \Treestyle
appears only once at the beginning
of the document and the style options are valid for all trees of the
document.
The changes in the style options are global. A \Treestyle
command
changes only the specified style options; non-specified options retain
the last specified value or the default value, respectively. The following
style options are available:
\treefonts{<font options>}
:
\treefonts
is invoked by \beginTree
, and it simply executes
whatever is specified in <font options>
. Defaults are
\treefonts{\tenrm}
(or \treefonts{\normalsize\rm}
in
LATEX).
\nodesize{<size>}
:
\nodesize
defines the size of the nodes. <size>
is a
dimension and specifies the diameter of circle nodes. The
width of square nodes is adjusted accordingly to be slightly
smaller than the diameter of circle nodes in order to
balance their appearance. Furthermore,
\nodesize
adjusts the amount of space by which the
baseline of the labels is placed beneath the center of the node.
The default value of \nodesize
suits the default of
\treefonts
(taking into account the size option
of LATEX's document style).
\vdist{<dimen>}
, \minsep{<dimen>}
,
\addsep{<dimen>}
:
vdist
specifies the vertical distance between two
subsequent levels of the tree. Default is \vdist{60pt}
.
\minsep
specifies the minimal horizontal distance between two
adjacent nodes. Default is \minsep{20pt}
.
\addsep
specifies the additional amount of horizontal space
by which two subtree siblings are pushed apart farther than
calculated by the RT algorithm,
if the level at which they are closest is beneath
their root level. Default is \addsep{0pt}
\extended
, \nonextended
:
\extended
in effect, the nodes of a binary
tree are placed in exactly the same way as they would be in the
associated extended version of the tree (the missing nodes are
assumed to have no labels). The default is \nonextended
,
that is the usual layout.
Some examples of tree descriptions are given in the next figures. A detailed description of the TreeTEX macros is given in [3].
