2.5.3.1 Constructors for CLIM Polygons and Polylines

The following functions can be used to create polylines and polygons:

make-polyline [Function]

Arguments: point-seq ```
&key
```

closed

make-polyline* [Function]

Arguments: coord-seq ```
&key
```

closed

Summary: Returns an object of class
standard-polyline
consisting of the segments connecting each of the points in *
point-seq*
(or the points represented by the coordinate pairs in *
coord-seq*
).

If *
closed*
is
t
, then the segment connecting the first point and the last point is included in the polyline. The default for *
closed*
is
nil
.

These functions capture their mutable inputs; the consequences of modifying those objects are unspecified.

make-polygon [Function]

Arguments: point-seq

make-polygon* [Function]

Arguments: coord-seq

Summary: Returns an object of class
standard-polygon
consisting of the area contained in the boundary that is specified by the segments connecting each of the points in *
point-seq*
(or the points represented by the coordinate pairs in *
coord-seq*
).

These functions capture their mutable inputs; the consequences of modifying those objects are unspecified.
