       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

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.

OPTIONS

       Basic options

       -i filename
              Add this file to the triangulation using this schema index

       -o filename
              Output the reconstructed polygons in this file

       -fix   Automagically repair (same as -rrlb -rrrn)

       -d     Dissolve the boundaries between regions with the same tag according to  the  schema
              index

       Possible steps (in usual processing order)

       -i filename
              Add this file to the triangulation using this schema index

       -t     Tag the triangulation

       -otnt filename
              Output the tagged triangulation with the number of tags to this file

       -vh    Consider holes as valid

       -sr ration
              Split invalid regions at triangles with a higher aspect ratio than this

       -v     Validate

       -au    Allow removing invalid regions (where convenient)

       -rtnn  Repair triangles by assigning them to the neighbour present on most sides

       -rtam  Repair triangles by assigning them to a neighbour present on at least 2 sides

       -rtlb  Repair  triangles by assigning them to the neighbour present along the longest part
              of their boundary

       -rrlb  Repair regions by assigning them to the neighbour present along the longest part of
              their boundary

       -rrrn  Repair regions by assigning them to a random neighbour

       -rpl filename
              Repair by assigning according to the priority list in this file

       -rem filename
              Repair for edge matching according to the priority list in this file

       -ot filename
              Output the triangulation to this file

       -otwp filename
              Output the triangulation to this file, including the input file where each triangle
              came from

       -bd    Removes unnecessary vertices before reconstruction to support larger data sets (try
              if you get a segmentation fault)

       -rp    Reconstruct polygons

       -o filename
              Output the reconstructed polygons in this file

       -owp filename
              Output the reconstructed polygons in this file, including the input file where they
              came from

       -pi    Print triangulation information
