<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.

<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.
