[gentoo-user] Making a new frame-buffer console font

[gentoo-user] Making a new frame-buffer console font

[Peter Humphrey]

[-- Attachment #1: Type: text/plain, Size: 2679 bytes --]

Hello list,

This is to summarise what I did in case anyone else wants to do
something similar.

Last May I was looking for a font that would distinguish the upper-case
letter O from the numbers 0 and 8 on a virtual TTY with a frame-buffer.
My difficulty was twofold: the available unicode fonts were all too
small, and the only bigger fonts I could find had an oblique stroke
through the zero which made it look like an eight[1], and some of them
even had serifs.

The first step was to find a font that looked good. I chose terminus
font, which included fonts up to 32 pixels tall and had an attractive
and easily read shape to its characters.

The second step was to find a font editor, and I found nafe[2]. I
fetched it and compiled it locally. GCC threw out an error but the
program seemed to work anyway. I followed its readme.txt and used the
text editor joe to replace the oblique stroke in the zero with spaces,
and to round the shoulders; I made sure I kept the line lengths the
same, though it's supposed not to be necessary. Lastly I gzip'd the new
font file.

The shoulders could be made more rounded, but for the moment I'm happy
with the result I have.

Thirdly, working at a virtual console, I replaced the original 
/usr/share/consolefonts/ter-v20n.psf.gz with my new version and called 
"etc/init.d/consolefont restart". Lovely!

There was still a problem though: when I ran a kernel menuconfig the
line characters were displayed as question marks; the system log on VT12
couldn't display all the characters right either.

The reason was straightforward. I'd noticed that nafe used file-name
suffix .psfu for fonts with unicode maps and .psf for those without.
Since all the files in /usr/share/consolefonts had .psf I assumed they
didn't need the map. Wrong. So I added the unicode map into my new.ter-
v20n.psf to make new.ter-v20n.psfu, then gzip'd it and copied it back
into /usr/share/consolefonts as ter-v20n.psf.gz. (Notice the missing u.)
Now I get the expected display of kernel menuconfig and the VT12 log.

The final step was to add /usr/share/consolefonts to CONFIG_PROTECT in
/etc/portage/make.conf so that I wouldn't lose my changes at the next
upgrade.

I've attached my three new console fonts for anyone who'd like to use
them. I've settled on the 22-pixel version pro tem.

Thanks to David Haller for getting me started by pointing me in the
right direction.

1.	Where did that oblique stroke come from? Was it just copied blindly
from those nasty old line printers, with their poor resolution? It must
surely be time now to get rid of it.

2.	Not another font editor: http://sourceforge.net/projects/nafe/files/nafe/nafe-0.1/

  A bit of a tangent... do you know of any font editors that will
convert a font to "double-wide"?  E.g. convert 8x8 to 16x8, 8x12 to
16x12, or 8x16 to 16x16.  The reason I ask is because I have a laptop
with a 1280x800 screen.  Back in the old days, the native VGA display
would've been 80 columns across.  But now with framebuffer drivers, the
straight text display is almost unreadable 160 columns across.  Going to
the Sun 12x22 font gives me 107 columns across, but that's still not
good.  That's why I'm looking for 16-pixel-wide fonts, either freely
available, or try to generate them from existing 8-pixel-wide fonts.

I think that would be a bit of a tall order, unless you're happy to 
accept glyphs all having double-thickness vertical lines.

Yes, that's what started me off on my hunt for acceptable fonts. This 
desktop screen is 27" and 1920x1080: evidently designed for 1080p video.

That one has serifs, doesn't it? Serif fonts work well in print with its 
much higher resolution, but IMO they're not a good idea on screens.

From my own experience I can only suggest terminus-font; you might find 
an acceptable compromise there as its heights range from 12 to 32 
pixels, so I suppose its widths will range from 6 to 16. Or perhaps some 
font will call itself [something]-wide.

There's also the problem that most work in typeface design these days 
(not counting the print world) seems to be in graphical settings -- X 
etc. -- so anything new would need some sort of conversion for use in a 
console.

Good luck in your hunt! I expect you'll need it :-(

  That's what I was looking for.  I did not expect natively designed
16-pixel-wide fonts.

I also use terminus-font as console font and even as X11 desktop font
since many years. It's readability is very good.

I like terminus a lot -- especially for low DPI use.  

I'm also very fond of sun12x22.psfu.gz as a console font for high DPI
situations [some of my affaction for that font is probably a result of
nostalgic feelings for my Sun-3 and Sun-4 boxes of old.]

I hadn't thought of it for Konsole, but now I have and I like it. But 
something's odd here: I've chosen the 17pt size, and I wanted to delete 
the oblique stroke from it, but as far as I can see there isn't a 17pt 
font anywhere on the system! Unless it's hidden in a file with no 17 in 
its name, or Konsole is scaling the font itself.

Any ideas, anyone?

Not all sizes are available, that's true. It is a little bit as a fixed
font. :-)

I don't know what you mean with oblique stroke. Do you mean the
slash through the letter zero? Anyway, I don't know how to remove it.

Sorry, I meant bitmap font and not fixed font. And I'm not sure, but I
think it is indeed a bitmap font.

Yes.

I've always been puzzled by that form of zero, and recently since it 
started causing me difficulty I've come to loathe it. :-(

Maybe I'll go back to Deja Vu Sans Mono for Konsole.

It dates back to the days when fonts were much coarser and it was the
only reliable way to distinguish between a zero and a capital o. Less
useful nowadays and many fonts no longer use it.

Yes, I know, but I can't see why it's survived so long after it stopped 
being useful.

Inertia? It's mainly the older fonts that have it, many no longer do.

I actively seek out and use fonts with a stroked zero (or at least with
a dot in the middle of the zero. I can never remember if the digit is
the fat one or the thin one

I'd have thought it was easy enough: the zero is the same width as the 
other numerals. The O is bigger.

You're as bad as me :P

In a mono font the O looks bigger because it fills more of the "tile", 
so just remember The Big O.

Anyone besides me use the ctrl + shortcut to zoom in?  I do that and I
have bi-focals on.   I also have a magnifying glass right in front of my

So instead of a font with a line through the zero, you have one where the
capital o wears dark glasses?

I tried varifocals but had to give them up. I now have three single-
focus pairs. At least with those, things are in focus at some distance, 
but with the varies nothing was ever in focus. Not good for driving.

I too have a magnifying glass to hand.
