Re: gEDA-user: output scale

["harry eaton" <bumpelo@comcast.net>]

"Correcting drawing to reality" had better be just a matter of correcting
for errors in the printer or photo-processess further down stream. If not,
you'd better change the layout itself.

That said, pcb's print scaling is not really intended for that purpose -
partly because to do it properly you need separate corrections for X and Y
scaling in most cases.

If you do want to make tiny adjustments to the scaling, I'd recommend simply
adjusting the postscript scale value(s). Any pcb postscript output will have
lines that look like:
...
gsave
0.00072 0.00072 scale
xxxxx  yyyyy translate
1.000 1.000 scale
....

where xxxxx and yyyyy depend on your design. Simply edit the "1.000" values
to tweak the scaling. (They are X and Y scalings).

Good luck,
harry

When you print out a layout, it can become out scale, so for instance longer
components will have the holes out of alignment (and is not mountable).
