Sample Application for GBRUnion LIB

Artwork provides a sample application, gbrunion_dynamic.exe, which illustrates how to use the library. We provide source code and project files for this sample app so that an OEM programmer can study it to see how to effectively use the library.

-window:<xmin,ymin,xmax,ymax>         Clip data to specified window.
                                      If not specified, the entire data file is

Test Program Options:

-dll:<dll_filename>              Specify Gerber Union DLL where <dll_filename> 
                                 is its full name.

-o:<output_txt>                  Specify output file of Test Program.

-useProgressCB                   Use callback function for progress display.

Command Line Examples

We want to convert a file called icsxseed.gbr into ascii using Leonov style polygons. The window we wish to extract goes from 5,5 to 6,6 (i.e about an inch square from a larger board)

Carriage returns have been inserted only for clarity. Comments are in italics.

"C:\WCAD\Gbrunion DLL\bin\gbrunion_dynamic.exe"           starts the calling application

"C:\WCAD\Gbrunion DLL\examples\icsxseed.gbr"              input file to process

"-dll:C:\WCAD\Gbrunion DLL\artwork\gbrunion.dll"          points to the location of the library

"-wdir:C:\WCAD\Gbrunion DLL\examples\work"                working directory is defined

"-o:C:\WCAD\Gbrunion DLL\examples\out\icsxseed_win.txt"   output file location and name

-thrnum:1                                                 number of concurrent threads

-useProgressCB                                            tells the app to use a callback for progress

-polyformat:1                                             tells the program to create Leonov polys
