README

        
5 October 2010

This directory contains some tools for generating TSP art for the Eggbot.

These tools have only been tested quite a bit under OS X 10.6.

These tools have had very limited testing on Windows XP SP3.

 25 Sep 2010 v0.1   Initial version

 27 Sep 2010 v0.1   Added --count and --runs options

 28 Sep 2010 v0.3   Added support for (x,y) and (x,y,radius) files

  1 Oct 2010 v0.4   Decided to close the TSP tour after all; added

                      --max-segments, and --fill options

  3 Oct 2010 v0.5   Added --line-color, --pre, --mid, & --post options for

                      color TSP art

  4 Oct 2010 v0.6   Added --layer for specifying layer names

  5 Oct 2010 v0.7   Fix help documentation, change --line-color to --stroke

  7 Oct 2010 v0.8   Added cmyk.jsx for Photoshop

 10 Oct 2010 v0.8.1 Added metadata; XML comment referencing Eggbot

  1 Dec 2011 V0.8.2 Fixed an incorrect error diagnostic which when output

                      prematurely ended processing; switched to a different

                      Python library for running linkern in a "subprocess"

                      so as to support current versions of Python on Windows 7

                      (thanks to Peter Vancorenland for diagnosing the issue,

                      researching a fix, and testing it!)

  7 Mar 2012 V0.8.3 Build the tour file in the user's temporary file directory.

                      This avoids issues with file permissions on some systems

                      where it's most convenient to run tspart.py from within

                      a specific directory that the user may not have write

                      access to.  Note that other temporary files were already

                      being written (and then removed) from the temp. directory.

                      For purposes of debugging, the tour file was being

                      written to the current working directory.  That is no

                      longer done.

build-concorde-osx.sh

  Shell script to obtain with Curl the QSopt LP Solver library and the

  Concorde TSP library and places them in /usr/local/src/concorde.

  The script then builds either a 32bit or 64bit version of the Concorde

  TSP library and places symlinks in /usr/local/bin/ for the concorde

  and linkern executables.  (Note: QSopt is not needed for linkern.)

  This script will need modification for Linux.

  While binary executables are available for concorde and linkern for

  Windows, they require a minimal cygwin install.  See

  http://www.tsp.gatech.edu/concorde/downloads/downloads.htm

cmyk.jsx

  Photoshop script for producing CMYK "separations" for Color TSP art.

  Tested on Mac OS X 10.6.4 with Photoshop CS5.

STIPPLING.txt

  Fifty words or less explaining how to do quick stippling in gimp.  A

  useful means of getting a bitmap to feed to tspart.py.

tspart.py

  Python script to accept as input a black and white bitmap file in PBM

  format and produce as output a SVG file (TSP art) arrived at by using

  the fast, heuristic TSP solver linkern.

  In addition to PBM files, a simple format allowing (x, y) or (x, y, radius)

  coordinates is also supported.  (E.g., the format output by some stippling

  software.) See the comments in tspbitcity.py for further details.

tspbitcity.py

  Python class used by tspart.py.  This is the class which reads in a

  PBM file and can generate a TSPLIB format file for concorde and linkern.

  Also, using a TSP tour, it can generate an SVG file.

  If run as a standalone Python script, tspbitcity.py will generate a

  TSPLIB file from a PBM file.

tspsolution.py

  Python class used by tspart.py.  This class reads a solution file from

  either concorde or linkern and determines the "tour".  This "tour" is

  then used by tspart.py to generate the output SVG file.
