Module to reshape vectors. The reshape operation includes the possibility to:
The reshape uses the ECQL language, please refer to the uDig user manual or the GeoTools documentation for more informations about the syntax and usability of the language.

Geometry changing examples:
To create a centroid layer from a polygon layer use:

the_geom=centroid(the_geom)

To create a buffer of 20 meters from a points layer use:

the_geom=buffer(the_geom, 20.0)

To create a convex hull from a points layer use:

the_geom=convexHull(the_geom)

Other examples:
To create a two new field containing the perimeter and area of the polygons in a layer:

area=area(the_geom)
length=geomLength(the_geom)

This is also the perfect way to create a new column in a shapefile layer and assign it a new default value:

newfield=-1
