- I just tested "romans2-scaled.lff, and its scale is just perfect!
  i.e.: Have the same size has IntelliCAD "ic-simplex.shx".

- Good job Rallaz.

- I updated the "simplex-1.lff" I created with this font.

  Good.

Ok.

- Attached, the "simplex-1.lff" font.

simplex-1.lff.zip

simplex does not exist in librecad so is changed:
if (style == "simplex") then style = "normallatin2";

when the font is finished then rename to simplex.lff
and change the code.

considerations:
The field "Format" should be version for possible formats redesigns like v12, v2000, v2007 in dwg
The field "Author" is also handled by LibreCAD and require a line starting by "# Author:" to handle it
and not lose any author when the file is saved.

Fields
"Created:", "Last modified:" and "Notes"  are treated as commentaries
If you open the font with LibreCAD, then saved, are lost.
I have to watch that when the file is saved do not miss the comments and update # Last modified:

I now I have little time and hard work
if you take care I would be happy :-)
And if you do, feel free to ask

Claude:
I have written a converter from jhf (Hershey fonts) to lff
Is a qt4 console, you can get it:
http://sourceforge.net/projects/rallaz.u/files/fontconverter/fontconverter.zip/download

I converted the file romans.jhf (in QCAD romans2.cxf) to romans.lff and added more chars, the same ones that were added by Adam Radlowski and the five vowels in capital and small, with open and closed accent.

This file is a good example in how to reuse chars definitions.
romans.lff

something else, what is your opinion regarding change already .cxf files for .lff?

Who are interested:

the above link have all Hershey fonts converted to .lff if someone else is encouraged to add characters
also have the font ISO-3098 in dwg and svg (in QCAD called normal, normallatin1, normallatin2 and standard)

Great!
This will enhance LibreCAD fonts a lot :-)

- Interresting.  So now, we can forget "romans2.cxf" and "romans2.lff",
   and use "romans.lff".

- Wondering if I can use your "romans.lff" as replacement for
   "simplex(-1).lff".
   I will take a look at that.

- By the way, I had no time to add accents on "simplex(-1).lff" :-(

- After doing some functional tests on all ".lff" fonts I was aware
   of, I think the ".lff" font format is mostly usable.

Good day! I tried LibreCAD and i liked it, but didn't find the font we use in our country as standard (Ghost Type A). Searching in the internet found a free version of ttf fonts i need (opengostfont-ttf-0.3). Could You convert them to lff and send me on e-mail (chymax3m@mail.ru). Hope to see these fonts included to new versions of LibreCAD. Good luck!

there's a ttf2lff tool comes with LibreCAD.

You can generate the lff fonts using ttf2lff. If you the ttf fonts are licensed by free software terms, we may include the lff fonts in LibreCAD.

I've uploaded an archive with fonts and license i've been writing about. Please include it into a new release. Regards, Vladymyr

P.S. I'm using Windows 7 SP1 x64, and couldn't find the ttf2lff tool for windows OS. Could You convert those font files and send it to my e-mail: chymax3m@mail.ru. Would be greatfull.

Thanks!

I will add it to both 2.0 and 1.0 series.

as 2.0.0beta1 already tagged, it should appear in 2.0.0beta2 release.

Would You be so kind to send me the converted fonts?

https://github.com/LibreCAD/LibreCAD/blob/master/librecad/support/fonts/OpenGostTypeA-Regular.lff
https://github.com/LibreCAD/LibreCAD/blob/master/librecad/support/fonts/OpenGostTypeB-Regular.lff

Thanks, i'd already written to dxli on e-mail about my trouble, but there were no answer. Those fonts are Cyrullic-type (Russian), but when i imported them in LibreCAD 2 beta 1 they reflected as some ASCII symbols, not letters. Is this the trouble of a new version of LibreCAD, or in me? And one more thing, sorry for offtop, the button "Grid" in main pannel doesn't create grid.
