NAME

gbtiler - Gbtiler is a program that can offset and merge gerber and NC drill files that represent circuit board artwork.

SYNOPSIS

--argfile [filename]      name of file of additional options.
                          Multiple argument files may be specified
                          on the command line which invokes gbtiler
                          but --argfile tags in external arguments
                          files are basically ignored.  In typical
                          use, only one external argument file
                          should be needed anyway.

DESCRIPTION most arguments are passed in a separate file, rather than on the command line when gbtiler is invoked, most file data is read line by line and written out to intermediate or final file as soon as processing is complete,

GBTILER OPTIONS 

--gerberfile [filename]   filename of Gerber source file to tile.

--drillfile [filename]    filename of NC drill file to tile.

--rackfile [filename]     filename of rack or tool file to
                          accompany a given NC drill file.

--outfile [filename]      output file name for tiled layer which
                          may be either a tiling of RS274X Gerber
                          files or a tiling of NC drill files, but
                          not a mix of both.

--path  [pathname]        path to prepend to all files up to next
                          --path option.  This option makes it
                          easier to include files to tile that are
                          located in different directories.  When
                          encountered, the script updates an
                          variable as it builds the hash of circuit

GLOBAL GBTILER OPTIONS:

The following gbtiler options normally would only appear once in
a list of arguments directing the processing work of gbtiler:

--offset [n.n,n.n]        offset to apply to input file data,
                          where n.n represent a real value whose
                          precision is limited practically to the
                          resolution of the board producing house,
                          and whose resolution is limited
                          programmatically to the precision of
                          floating point supported by the end-
                          user's version of Perl.

--leading_zeroes [n]      toggles leading zero formatting on 
                          and off. Not yet fully implemented
                          in gbtiler 2.0.

--trailing_zeroes [n]     toggles trailing zero formatting on
                          and off. 

--x_integer_digits [n]    output file coordinate formatting,
                          n is an integer value between 1 and 6
                          inclusive.  This description of n
                          applies to the remaining global
                          arguments in this list.

--x_decimal_digits [n]    output file coordinate formatting,

--y_integer_digits [n]    output file coordinate formatting,

--y_decimal_digits [n]    output file coordinate formatting.



 VERSION 2.0 GLOBAL OPTIONS:

--created_by [program name]   not yet implemented, and may not be
                              needed for external drill rack
                              processing.

--drill_substitution ["apc"]  this option currently toggles on and
                              off a limited drill size substituting
                              routine which tries to simplify the
                              set of drills used in a file to the
                              seven standard drills available at
                              Alberta Printed Circuits, Inc.
                              Drill sizes outside this set add
                              extra charges to the cost of
                              producing a board.
