Command Line Syntax
The InkRaster executable is controlled by a command line. The syntax is shown below:
inkraster64.exe <input> -out:<outfile> [optional arguments] where: inkraster64.exe full path to the executable input input Gerber file (RS274X). appears to require a full path - does not work with relative or no path. -out:outfile full path to the output bitmap file no file extension needed; it will be added based on output file type. Optional Arguments ----------------------------------------------------------------------------------- -h display the command line syntax -bmp output monochrome BMP - otherwise defaults to monochrome TIFF (packbits) -workdir:<dir> working directory for temporary files does not appear to be an "optional" argument. -log:<filename> full path to the log file -thrnum:N number of concurrent threads to use -dpi:<val>[,<val>] DPI - single value or X,Y value -droplet:<size> droplet diameter (value in units defined with the -unit command line option) -coverage:<fill>,<edge> ink coverage parameters (0-1) for the interior (fill) and the periphery (edge) Details -compensate:<fill>,<edge> droplet compensation values for interior and edge. Details -window:<minX,minY,maxX,maxY> rasterize this window only. (in input units) -mirror:<x|y|xy> mirror about X or Y axis or both X and Y -rotate:<X> rotate X degrees (CCW for positive values) -scale:<val>[,<val>] scale the data (independent X and Y if desired) -margin:<val>[,val][px] when no window is defined the data extents will be computed. Use the margin to add area around the data extents. A single value is applied around all edges of the extents. If two values are specified one can control the left/right and top/ bottom margin independently. If all 4 values are specified they apply to left,right,top and bottom respectively. Margin values are in: input file units if -unit is not used; the setting for -unit if it is specified; in pixels if the last margin value is followed by px. -reversal reverse the polarity of the input data and clip to extents (or window or extents plus margin) -minfeature:<size> minimum geometry feature size (features below this value will not be rasterized.) Defaults to [droplet dia]/2 -unit: mm | um | inch | mil sets the units for the following other arguments: -droplet, -minfeature, -window, -margin, -border, -offset, -anchor this argument is optional. If not used, units match those of the input Gerber file. -keep_tmp keep temporary working files. Default is to delete them when program is complete. -silent run in silent mode - i.e. no progress -drop OK to drop narrow features - disables the narrow line recovery module. -extent computes the data extents and writes the results to the output file. (No rasterization)
Command Line Examples
Here is an example where the command line (located in the current directory) processes a Gerber file also located in the current directory. There are two sub-directories in the current directory: "output folder" is for the output bitmap and "working files" will hold the temporary working files. The output will be TIFF packbits since that is the default output.
C:\wcad\inkraster64\inkraster64.exe full path to executable %CD%\demo1.gbr input file (%CD% is current directory) "-out:%CD%\output folder\demo1.tif" output file (note quotes for paths or file names with spaces.) "-workdir:%CD%\working files" working directory. -log:%CD%\output folder\demo1.log log file -dpi:1050 DPI setting -droplet:0.060 droplet diameter in Gerber input units -coverage:0.5,1 ink coverage parameters -offset:1,0.5 droplet offset (0.5 for outer edge is standard usage)
How to Get the Extents of a Gerber File
C:\wcad\inkraster64\inkraster64.exe full path to executable %CD%\demo1.gbr input file (%CD% is current directory) -workdir:\%CD%\working working directory for temp files "-out:%CD%\output folder\demo1" output file (note quotes for paths or file names with spaces.) -extent compute data extents and write to output file.
The results will be a text file (demo1.txt) that contains the lower left and upper right extents:
-10.505000 -3.995000 12.755000 21.995000
