I have extensively tested a large number of free TrueType fonts in order to increase the readability in tuxtxt. Many of the popular available fixed width fonts looks bad, like Inconsolata, Monotype Typewriter, Envy R, Vera Sans Mono, and the likes. I did however finally find one excellent font: Liberation Mono Bold.

As this looks much better than the provided tuxtxt TrueType font in OpenPLi, would it be possible to switch to Liberation Mono Bold since it is GPL:ed?

Steps to switch and activate the font in any version of OpenPLi:
[list=1]
[*]Download this font pack https://fedorahosted...20091227.tar.gz (or later version)
[*]Unpack and copy the font LiberationMono-Bold.ttf as /usr/share/fonts/tuxtxt.ttf
[*]Edit the file /etc/tuxtxt/tuxtxt2.conf and change to "UseTTF 1"[/list]Enjoy!

Visually they are about the same size. On disk the provided TTF is 49k and this one is 105k.

did you test this both with e1 and e2? (they use different tuxtxt versions).
Also, I seem to remember there were issues with the ttf support of tuxtxt (font dimensions were ignored, so glyph positioning was not perfect).

That's why we ended up disabling ttf in the config.
But if for currrent versions things look fine with ttf, using your font, we could make the switch.

(however, for the 500 maxvar image it will be hard finding 55K of additional space...)

just tested this with the 20090130UTC which we use for e2.
The glyphs do not fit in their bounding boxes; for instance the 'g' drops 1 pixel below it, so it's cropped.
Also, when the background color changes (probably because of txt level 2.5) the glyph backgrounds become messed up.

So unfortunately, TTF support seems incomplete/broken, at least in more recent tuxtxt versions.

Good input Lasa, thanks. Really disliked those huge bold characters on my HD set...

I have even tried more of your list and now selected (standard for me) LiberationMono-Regular.ttf.

Beautiful and thin characters! Really 'liberation' :)

Let's make teletext more beautiful, otherwise it could disappear from our screens, like in Belgium.

For me it's part of my daily routine, reading teletext. This font really makes it more pleasant.

Also try to change 'ShowLevel2p5' to 0.

 

In level 2.5 background changes per section, this is bad for contrast.

Somewhere mid 90's this decision was made. At the TV development lab we could not understand why, but it happened ...

Now you can change this back for yourself I just discovered...

 

Switching level 2.5 off, makes you always have a black background.

 

Thin yellow letters on pure black contrasted background.

 

Try and enjoy ... ;)

Thanks mrvica. Just tried, good work!

 

It is a bit receiver-tv dependent, because with the sharp set I am testing here 'LiberationMono-Regular.ttf.' seems best and seems also more constant, but with another set it looks horrible ... not sharp/bad contrast.

 

On my set here 'tuxtxt_prestige.ttf' is close 2nd and 'tuxtext_prestige_bd.ttf' also very good ;)

 

Perhaps the prestige fonts are more 'portable' (?)

 

Everybody should try for themselves and give some vote/ranking here on the forum!

 

Perhaps the firmware developers can use this feedback information somewhere for future releases (?)

 

It is a pity the USB/wireless keyboard is not having the coloured keys, is there perhaps some file like 'button setup' we can edit ?
