Bitstream Vera Fonts Copyright
|
||||
|
||||
The fonts have a generous copyright, allowing derivative works (as
|
||||
long as "Bitstream" or "Vera" are not in the names), and full
|
||||
redistribution (so long as they are not *sold* by themselves). They
|
||||
can be be bundled, redistributed and sold with any software.
|
||||
|
||||
The fonts are distributed under the following copyright:

Copyright FAQ
|
||||
=============
|
||||
|
||||
1. I don't understand the resale restriction... What gives?
|
||||
|
||||
Bitstream is giving away these fonts, but wishes to ensure its
|
||||
competitors can't just drop the fonts as is into a font sale system
|
||||
and sell them as is. It seems fair that if Bitstream can't make money
|
||||
from the Bitstream Vera fonts, their competitors should not be able to
|
||||
do so either. You can sell the fonts as part of any software package,
|
||||
however.
|
||||
|
||||
2. I want to package these fonts separately for distribution and
|
||||
sale as part of a larger software package or system. Can I do so?
|
||||
|
||||
Yes. A RPM or Debian package is a "larger software package" to begin
|
||||
with, and you aren't selling them independently by themselves.
|
||||
See 1. above.
|
||||
|
||||
3. Are derivative works allowed?
|
||||
Yes!
|
||||
|
||||
4. Can I change or add to the font(s)?
|
||||
Yes, but you must change the name(s) of the font(s).
|
||||
|
||||
5. Under what terms are derivative works allowed?
|
||||
|
||||
You must change the name(s) of the fonts. This is to ensure the
|
||||
quality of the fonts, both to protect Bitstream and Gnome. We want to
|
||||
ensure that if an application has opened a font specifically of these
|
||||
names, it gets what it expects (though of course, using fontconfig,
|
||||
substitutions could still could have occurred during font
|
||||
opening). You must include the Bitstream copyright. Additional
|
||||
copyrights can be added, as per copyright law. Happy Font Hacking!
|
||||
|
||||
6. If I have improvements for Bitstream Vera, is it possible they might get
|
||||
adopted in future versions?
|
||||
|
||||
Yes. The contract between the Gnome Foundation and Bitstream has
|
||||
provisions for working with Bitstream to ensure quality additions to
|
||||
the Bitstream Vera font family. Please contact us if you have such
|
||||
additions. Note, that in general, we will want such additions for the
|
||||
entire family, not just a single font, and that you'll have to keep
|
||||
both Gnome and Jim Lyles, Vera's designer, happy! To make sense to add
|
||||
glyphs to the font, they must be stylistically in keeping with Vera's
|
||||
design. Vera cannot become a "ransom note" font. Jim Lyles will be
|
||||
providing a document describing the design elements used in Vera, as a
|
||||
guide and aid for people interested in contributing to Vera.
|
||||
|
||||
7. I want to sell a software package that uses these fonts: Can I do so?
|
||||
|
||||
Sure. Bundle the fonts with your software and sell your software
|
||||
with the fonts. That is the intent of the copyright.
|
||||
|
||||
8. If applications have built the names "Bitstream Vera" into them,
|
||||
can I override this somehow to use fonts of my choosing?
|
||||
|
||||
This depends on exact details of the software. Most open source
|
||||
systems and software (e.g., Gnome, KDE, etc.) are now converting to
|
||||
use fontconfig (see www.fontconfig.org) to handle font configuration,
|
||||
selection and substitution; it has provisions for overriding font
|
||||
names and subsituting alternatives. An example is provided by the
|
||||
supplied local.conf file, which chooses the family Bitstream Vera for
|
||||
"sans", "serif" and "monospace". Other software (e.g., the XFree86
|
||||
core server) has other mechanisms for font substitution.
