<H2>polygon</H2>
<HR>
Generate polygons from the command line.
<HR>
<H3>Shortcuts:</H3>
<BLOCKQUOTE>
None.
</BLOCKQUOTE>
<H3>Usage:</H3>
<BLOCKQUOTE>
<B>polygon</B> <I>type x1 y1 x2 y2</I> ... <I>xn yn</I> <BR><BR>
<BLOCKQUOTE>
where <I>type</I> is a tile type to draw, and <I>x1 y1</I> ...
<I>xn yn</I> are <I>n</I> vertices of a polygon.
</BLOCKQUOTE>
</BLOCKQUOTE>
<H3>Summary:</H3>
<BLOCKQUOTE>
The <B>polygon</B> command allows generation of polygons on the
layout from the command line, similarly to the <B>wire segment</B>
command. The <B>polygon</B> command automatically generates the
proper tile geometry for the polygon as specified by vertices.
Vertex points are pairs of X Y coordinates, and may take any
dimensional value (default lambda, but may be internal units or
metric units). Note that polygons should be convex; the tile
generation algorithm is not guaranteed to work with non-convex
geometries. <P>
While simple non-Manhattan structures (triangles) can be generated
with the "splitpaint" and "spliterase" commands using macros, there
is no convenient interactive method for generating complex polygon
geometry. The <B>polygon</B> command is best used in scripts to
create specific patterns based on known geometry.
</BLOCKQUOTE>
<H3>Implementation Notes:</H3>
<BLOCKQUOTE>
<B>polygon</B> is implemented as a built-in command in <B>magic</B>.
