Re: [Gerbv-devel] aperture macro a bit on the way

[Julian <the...@gm...>]

Stefan,
   What did you think of my earlier idea about "compiling" the macro
definitions down to actual macro primitives during the parsing?  For
example, if the user uses an aperture that uses an aperture macro,
amacro.cwould go through the program and calculate exactly what
primitives to draw
and then store each of these primatives in a gerb_net_t somehow (for
example, the "rounded corners rectangle" program that was submitted to
geda_user might store a 4x2 rectangle and 4 0.5" diameter circles each time
the aperture was flashed in the program).  This would also allow the parser
to calculate the exact mix/max x and y values for autoscaling, too.  Right
now, the parser doesn't really know how large the macros are and autoscales
incorrectly sometimes.  I've also just implemented the knockout Gerber
feature which sometimes needs to know the exact size of all apertures for
its "border" mode where it draws a clear box around all apertures after it.
These could both be handled if we compiled all aperture macros during the
parsing.

Let me know your thoughts.  Cheers,
Julian
