Postscript needs no parsing as you can directly interpret it with data and graphics stacks. > just the absolute > minimum to extract the vectorial drawing coordinates, start point and > end point. > I suggest you take a look at the library provided by ghostscript and also the various gs widgets. > I am a little impressed that everyone says postscript is so complex, > so I'm reevaluating which path to go, but I do have a competent > software developer available to whom send the task, so the amount of > work isn't that much a problem =P (as long as it is doable by 1 person > in a couple of months) > just curious: does corel draw generate vectorial output? otherwise your postscript output will contain a huge (ugly) bitmap... cheers, -Krishna -- One reason that life is complex is that it has a real part and an imaginary part -Andrew Koenig _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
