NAME
pprepair - planar partition repair tool
SYNOPSIS
pprepair [ [-i filename [schemaindex]] [-o filename] [-fix] [-d] | -p [-i filename [ schemaindex]] [-t] [-otnt filename] [-vh] [-sr ratio] [-v] [-au] [-rtnn] [-rtam] [-rtlb] [-rrlb] [-rrrn] [-rpl filename] [-rem filename] [-ot filename] [-otwp filename] [-bd] [-rp] [-owp] [-o filename] [-pi] ]
DESCRIPTION
pprepair (planar partition repair) takes a set of polygons and ensures that they form a valid planar partition, made of valid polygons and having no gaps or overlaps. It can be used as a validator, telling of problems in individual polygons or in the planar partition, and also as an automatic repair tool, outputting a set of polygons that do form a valid planar partition.
