Hello everyone -
I have defined a custom symbol for electric light fixtures. The MetaPost code
is below. Now that I have used it, I find that it draws the symbol too large.
I tried using "-scale small" and "-scale tiny", and that helps. Rather than go
through and add that to every point, I would like to change the MetaPost so it
draws the symbol a bit smaller.
And I am lazy! I could replot all the points for each of the lines. It seems
to me there should be a simpler way. I tried messing with the U:= parameters,
but they seem to make no difference whatever.
Is there a way I can declare a multiplier in the MetaPost code? Perhaps
declaring u = 0.6u?
Thanks!
