Recompile, sorry. See libgeda/src/o_text_basic.c

Search:

#define GEDA_FONT_FACTOR 1.3

You probably want it "1.0"

The on-screen scaling ought not to have changed (much), as the scaling
factor above was designed to match (as closely as possible), the height
of the old gEDA font.

It does mean that postscript output has seen its font size increase (by
a factor of x1.3). Sometimes I still think I made the wrong decision in
doing it that way.

The choice was either smaller on-screen fonts compared to pre gEDA
1.6.0, or try to match on-screen - and increase the postscript output
size.

I really wish I'd fixed 1-1, and just shrunk the on-screen rendering
now. Unfortunately, this isn't something we can easily change back - as
consistency is good.

Technically, it "could" go in a 1.6.1 update - but I suspect there would
be a lot of (valid) opposition to that, since it isn't really a "bug
fix" per-se.

Got it in one there.

I avoided making if configurable deliberately - since it adds yet
another variable in the already confusing array of settings.

One thing I'm absolutely against is introducing separate on-screen, and
output scalings. gschem is WYSIWYG, and something I think we want to
keep.

I'm not violently opposed to adding a setting for the scaling factor -
but I'd really prefer it wasn't necessary.

Ok, cool - glad to hear they are working for you.

Best wishes,
