The gbr2tiff program is often run from the command line. The complete syntax and options are shown below. Note that there are no breaks in the command line - the breaks shown below are only for clarity.
gbr2tiff.exe
gbrfile(s)
{-apt:aptfile | -274x}
[-xf xformfile]
[-ram:R]
[ outtype:outputfile ]
[other_options]
where
gbr2tiff the gbr2tiff program
gbrfile the Gerber file to be ripped
-apt:aptfile the name of the aperture list (assuming that
the input file is RS274D. There is no need
for an .apt file in the input is RS274X)
-274x indicates input file is a 274X file
-xf:xformfile optional; name of an ascii file contain
transform parameters for mirroring, rotation
and scaling.
-ram:R use R as the raster buffer size (Mb)
The following output types are available (outtype:filename) Select one:
-tiff:outputfile output file in 1 bit tiff; uncompressed
-pack:outputfile output file is 1 bit tiff; packbits comp.
-ps2:outputfile output in Postscript II (uncompressed)
-cps2:outputfile output is Postscript II RLE compression
-bmp::outputfile output in Windows BMP (monochrome)
-bitmap:outputfile output is raw bitmap (uncompressed)
-atf:outputfile output is custom for Automatech
[other options] if on command line override xform file
-units: {inch | mm} specifies xformfile units
with the exception of Resolution (DPI)
which is always in inches
(aliases -inch, -mm)
-dpi:DPI specifies DPI setting (alias -DPI#)
-enhanced turns off enhanced mode; allows bitmap copy
operation for faster RIP speed (default is
enhanced RIP precision)
-inverse output polarity is reversed
-super:[8 | 16 ] super sample output (-tiff only)
-color[:2 | 16 | 256] set BMP output to 2, 16, or
256 greyscale modes (BMP only)
-color[:black | red | green | yellow | blue | magenta | cyan]
set Postscript II color (Postscript II only)
-asizeup:X size aperture info up by X units
-round:{best | up | down | none} used with pixel subsampling; sets
which rule to use
-stroke:{best | left | right | none} controls adjustment of stroked
objects.
-flatness:N arc chord error is not to
exceed N pixels
-rotate:A rotate image A degrees (alias -rA)
(when using -imagesize -rotate:auto is valid)
-scale:X[,Y][@P,Q] scale data by X and Y in the x
and y directions respectively
(optionally about the point P,Q)
(default: X = Y) (alias -sX)
-shift:X,Y translate data by X and Y
(incompatible with -wplot)
-xmirror:X reflect data about the line x = X
(-wplot implies simple X mirror, i.e. -mirror:x)
-ymirror:Y reflect data about the line y = Y
(-wplot implies simple Y mirror, i.e. -mirror:y)
-step:Nx,Ny,Dx,Dy arrays data in an Nx by Ny rectangular
array with spacing of Dx and Dy
-image:X,Y rasterize data in the window from the origin
to X,Y (incompatible with -wplot)
-imagesize:X,Y[,x,y] dimension of image is X,Y. if the offsets x,y
from lower left are not specified, the image
is centered.
-wplot x0,y0 x1,y1 rasterize data in the window from x0,y0(LL)
to x1,y1(UR) (incompatible with -image)
-pause don't run right away, wait for user intervention.
-status run visibly.
-logcalls record the calls to setupFunc to plot.log
for debugging purposes.
-nopad do not pad tiff output to the nearest byte.
-noplot do not create any output, rip data only;
for debugging purposes.
-scanonly do not create any output, scan
input GERBER file only
-usedisk create TIFF packbits from raw bitmap image
on disk (for use with -pack)
-aw autowindow data (overrides -wplot parameters).
-margin:X provide a border of X units (used in conjunction
with -wplot or -aw).
-dothreads run a single thread at a time
+dothreads run multiple threads at a time
-maxt:N run at most N threads at a time
Engine Arguments arguments that follow -engargs do not affect
GBR2TIFF but are passed to the gbrplt.dll
argument list.
-engargs
-blowup:N generate an arithmetic exception after N counts
-msgcbs suppress popups and make use of
message callbacks instead
-keep do not delete file droppings
-logmem report memory statistics to plot.log
-loglibs log library usage to plot.log
-oem:ID use ID for keyless operation
-maxstrip:N allow N ATF strips (default: 6)
