More than 6 months ago, I wrote about generating TTF versions of the
(and published mine on that occasion), but I didn’t actually explain
how to generate them.
I found the answer to my problem (“How do I get TTF files from the
Terminus BDF source files?”) in the FontForge
- Create a new font.
- Import the different sizes (one BDF file per font size). Make sure to
import the BDF file with the biggest bitmaps into the glyph background!
- Select all glyphs.
- Autotrace them.
- Add extrema.
- Simplify all glyphs.
- Save as TTF.
This process requires the AutoTrace
program and FontForge, obviously. While
repeating these steps at least two times (for the medium and bold
versions of Terminus) is not that hard, I really like to automate
things. I also wanted an italic version (I accomplished that by running
the BDF files through
Fortunately, FontForge is
allowed me to write a script in FontForge’s own “legacy” scripting
language (the build I used didn’t support Python scripts…) to perform
the steps described above, a small wrapper for AutoTrace to remove the
obnoxious borders it adds to the resulting Postscript “images” and a
small shell script wrapper that runs mkitalic to produce italic BDF
files, tells FontForge to use my AutoTrace wrapper and finally runs the
FontForge script for the three different font weights (medium, bold and italic).
Since I had to do some research to obtain the above information, I
thought it would be nice to allow other people to easily generate TTF
versions of Terminus (mind you, I might lose interest some day!). The
scripts I wrote were only tested on unixoid systems (I didn’t test
whether they correctly run on Windows, e. g. using Cygwin or CoLinux;
they probably do, though).
Get the scripts here: https://github.com/Tblue/mkttf/archive/master.zip.
Also check out my Git repository on GitHub.
Read the included README file for information on how to use the
mkttf.sh script. Feel free to post comments (questions, constructive criticism…)!
You might want to use these scripts to generate TTF versions of other
fonts than Terminus, too; since the scripts are all fairly generic, it
should be sufficient to modify mkttf.sh.
