<H3>Summary:</H3>
|
|
|
|
|
<BLOCKQUOTE>
|
|
|
|
|
The <B>label</B> command places a label on the layout. The label
|
|
|
|
|
is marked by a point, line, or rectangle, depending on the size
|
|
|
|
|
of the cursor box. If the area under the cursor box contains
|
|
|
|
|
exactly one type, the label will be "attached" to that type; that
|
|
|
|
|
is, the label will name the network of the node containing that
|
|
|
|
|
type. If the area under the cursor box contains multiple layers,
|
|
|
|
|
one will be chosen for attachment to the label. If there are
|
|
|
|
|
multiple network nodes under the cursor box, the result may not
|
|
|
|
|
be what the user intended; in such cases, the user should specify
|
|
|
|
|
which <I>layer</I> the label should be attached to, so that the
|
|
|
|
|
appropriate network node will be labeled. <P>
|
|
|
|
|
|
|
|
|
|
The label text is placed to one side of the marker in the
|
|
|
|
|
direction indicated by the <I>position</I> argument. For
|
|
|
|
|
example, "<B>label text north</B>" will draw the label string
|
|
|
|
|
"<TT>text</TT>" to the north (above) the marker. <P>
|
|
|
|
|
|
2022-01-21 16:44:13 +01:00
|
|
|
In versions of <B>magic</B> prior to 8.0, labels cannot be
|
|
|
|
|
directly modified; modifications should be handled by first
|
|
|
|
|
erasing the label with "<B>erase label</B>" and then redrawing.
|
|
|
|
|
Versions 8.0 and higher use the <A HREF=setlabel.html><B>setlabel</B></A>
|
|
|
|
|
command to modify selected labels. <P>
|
|
|
|
|
|
|
|
|
|
Versions of <B>magic</B> from 8.0.139 allow the <I>layer</I> name
|
|
|
|
|
to have a dash ("<B>-</B>") in front (e.g., "<B>-metal1</B>") to
|
|
|
|
|
indicate a "sticky label", that is, one that is attached to the
|
|
|
|
|
specified layer type <I>layer</I>, and which cannot be reattached
|
|
|
|
|
to another layer. <P>
