Buffer Polygons

Command line

The Buffer Polygons operation can be directly executed by typing the following expression on the command line of the Main window:

  

OUTMAP

=

PolygonMapBuffer(InputPolygonMap, distance, endstyle)

where:

OUTMAP

is the name of your output polygon map.

PolygonMapBuffer

is the command to start the Buffer Polygons operation.

InputPolygonMap

is the name of the input polygon map.

Distance

The distance between the boundary of the bufferd polygon and the old boundary. Negative numbers indicate a buffer to the inside of the Polygon.

End style

The shape of the ending of vertices forming the buffered polygon. Possible styles are 'Round', 'Butt' and 'Square'

When the definition symbol = is used, a dependent output map is created; when the assignment symbol := is used, the dependency link is immediately broken after the output map has been calculated.
