GDSCompact is a command line based program and should be executed from a writable working directory.

The command line syntax can be obtained by running $gds_compact -h

Syntax

gds_compact inputfile outputfile [options]

where

gds_compact        full path to the executable

inputfile          path/name of the input GDSII stream file

outputfile         path/name of the output GDSII stream file

[options]          command line options

-h                 show the command line syntax

layers             a list of layers in the form: +1+2+3. If not specified
                   all layers found in the input file are processed.

-maxpts:4096       maximum number of vertices per boundary. range from
                   200 to 8191. Adjust this to whatever value the target
                   system supports.

-text              if this argument is present, text will not be passed
                   to the output. Default is to pass text to output.

-zwp               if this argument is present, any paths with zero width
                   will not be passed to output. Default behavior is to
                   pass zero width paths to the output.
