<H2>ruler</H2>
<HR>
Create ruler markings inside the box with indicated text.
<HR>
<H3>Usage:</H3>
<BLOCKQUOTE>
<B>ruler</B> [<I>text</I> [<I>orient</I>]] <BR><BR>
<BLOCKQUOTE>
where <I>orient</I> is either <B>vertical</B>,
<B>horizontal</B>, or <B>auto</B> (the default), and
where <I>text</I> is any string. If the string
contains whitespace, it must be quoted.
</BLOCKQUOTE>
</BLOCKQUOTE>
<H3>Summary:</H3>
<BLOCKQUOTE>
The <B>ruler</B> command generates a "ruler", a set of lines indicating
a dimension. It is used to annotate layouts with the indicated text.
If no orientation is given, then automatic orientation it used, in
which the presented dimension (the line or lines with arrowheads)
is whichever box dimension (width or height) is longer. The ruler
may be removed with the <B>unmeasure</B> command. The <B>measure</B>
command is a specific type of ruler where the text is set to the
presented box dimension.
</BLOCKQUOTE>
<H3>Implementation Notes:</H3>
<BLOCKQUOTE>
<B>ruler</B> is implemented as a Tcl procedure defined
in the "tools" script. It generates a set of elements (lines and
text) with the <B>element add</B> command.
