Chopper

From Fmepedia

Chopper is a Workbench Transformer.

Description

Ensures that all features output have less than or equal to <maximum vertices> vertices. This is useful if you're outputting to a format that has limitations on the number of points in lines or areas. It can also be used to crudely simplify complex objects.

When an area feature is chopped, the result will still be a number of closed areas.

A Chopper set to 1 will turn area and line features into point features.

Update for FME2009

As of build 5556 in FME2009 the Chopper transformer has undergone a major improvement in the algorithm used to chop polygons.

The improvement results in:

   * Faster Computation
   * A Reduced number of output features
   * More visually appealing output
