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. |

Bitstream Vera Fonts - April 16, 2003 |
|
||||||
===================================== |
|
||||||
|
|
||||||
The version number of these fonts is 1.10 to distinguish them from the |
|
||||||
beta test fonts. |
|
||||||
|
|
||||||
Note that the Vera copyright is incorporated in the fonts themselves. |
|
||||||
The License field in the fonts contains the copyright license as it |
|
||||||
appears below. The TrueType copyright field is not large enough to |
|
||||||
contain the full license, so the license is incorporated (as you might |
|
||||||
think if you thought about it) into the license field, which |
|
||||||
unfortunately can be obscure to find. (In pfaedit, see: Element->Font |
|
||||||
Info->TTFNames->License). |
|
||||||
|
|
||||||
Our apologies for it taking longer to complete the fonts than planned. |
|
||||||
Beta testers requested a tighter line spacing (less leading) and Jim |
|
||||||
Lyles redesigned Vera's accents to bring its line spacing to more |
|
||||||
typical of other fonts. This took additional time and effort. Our |
|
||||||
thanks to Jim for this effort above and beyond the call of duty. |
|
||||||
|
|
||||||
There are four monospace and sans faces (normal, oblique, bold, bold |
|
||||||
oblique) and two serif faces (normal and bold). Fontconfig/Xft2 (see |
|
||||||
www.fontconfig.org) can artificially oblique the serif faces for you: |
|
||||||
this loses hinting and distorts the faces slightly, but is visibly |
|
||||||
different than normal and bold, and reasonably pleasing. |
|
||||||
|
|
||||||
On systems with fontconfig 2.0 or 2.1 installed, making your sans, |
|
||||||
serif and monospace fonts default to these fonts is very easy. Just |
|
||||||
drop the file local.conf into your /etc/fonts directory. This will |
|
||||||
make the Bitstream fonts your default fonts for all applications using |
|
||||||
fontconfig (if sans, serif, or monospace names are used, as they often |
|
||||||
are as default values in many desktops). The XML in local.conf may |
|
||||||
need modification to enable subpixel decimation, if appropriate, |
|
||||||
however, the commented out phrase does so for XFree86 4.3, in the case |
|
||||||
that the server does not have sufficient information to identify the |
|
||||||
use of a flat panel. Fontconfig 2.2 adds Vera to the list of font |
|
||||||
families and will, by default use it as the default sans, serif and |
|
||||||
monospace fonts. |
|
||||||
|
|
||||||
During the testing of the final Vera fonts, we learned that screen |
|
||||||
fonts in general are only typically hinted to work correctly at |
|
||||||
integer pixel sizes. Vera is coded internally for integer sizes only. |
|
||||||
We need to investigate further to see if there are commonly used fonts |
|
||||||
that are hinted to be rounded but are not rounded to integer sizes due |
|
||||||
to oversights in their coding. |
|
||||||
|
|
||||||
Most fonts work best at 8 pixels and below if anti-aliased only, as |
|
||||||
the amount of work required to hint well at smaller and smaller sizes |
|
||||||
becomes astronomical. GASP tables are typically used to control |
|
||||||
whether hinting is used or not, but Freetype/Xft does not currently |
|
||||||
support GASP tables (which are present in Vera). |
|
||||||
|
|
||||||
To mitigate this problem, both for Vera and other fonts, there will be |
|
||||||
(very shortly) a new fontconfig 2.2 release that will, by default not |
|
||||||
apply hints if the size is below 8 pixels. if you should have a font |
|
||||||
that in fact has been hinted more agressively, you can use fontconfig |
|
||||||
to note this exception. We believe this should improve many hinted |
|
||||||
fonts in addition to Vera, though implemeting GASP support is likely |
|
||||||
the right long term solution. |
|
||||||
|
|
||||||
Font rendering in Gnome or KDE is the combination of algorithms in |
|
||||||
Xft2 and Freetype, along with hinting in the fonts themselves. It is |
|
||||||
vital to have sufficient information to disentangle problems that you |
|
||||||
may observe. |
|
||||||
|
|
||||||
Note that having your font rendering system set up correctly is vital |
|
||||||
to proper judgement of problems of the fonts: |
|
||||||
|
|
||||||
* Freetype may or may not be configured to in ways that may |
|
||||||
implement execution of possibly patented (in some parts of the world) |
|
||||||
TrueType hinting algorithms, particularly at small sizes. Best |
|
||||||
results are obtained while using these algorithms. |
|
||||||
|
|
||||||
* The freetype autohinter (used when the possibly patented |
|
||||||
algorithms are not used) continues to improve with each release. If |
|
||||||
you are using the autohinter, please ensure you are using an up to |
|
||||||
date version of freetype before reporting problems. |
|
||||||
|
|
||||||
* Please identify what version of freetype you are using in any |
|
||||||
bug reports, and how your freetype is configured. |
|
||||||
|
|
||||||
* Make sure you are not using the freetype version included in |
|
||||||
XFree86 4.3, as it has bugs that significantly degrade most fonts, |
|
||||||
including Vera. if you build XFree86 4.3 from source yourself, you may |
|
||||||
have installed this broken version without intending it (as I |
|
||||||
did). Vera was verified with the recently released Freetype 2.1.4. On |
|
||||||
many systems, 'ldd" can be used to see which freetype shared library |
|
||||||
is actually being used. |
|
||||||
|
|
||||||
* Xft/X Render does not (yet) implement gamma correction. This |
|
||||||
causes significant problems rendering white text on a black background |
|
||||||
(causing partial pixels to be insufficiently shaded) if the gamma of |
|
||||||
your monitor has not been compensated for, and minor problems with |
|
||||||
black text on a while background. The program "xgamma" can be used to |
|
||||||
set a gamma correction value in the X server's color pallette. Most |
|
||||||
monitors have a gamma near 2. |
|
||||||
|
|
||||||
* Note that the Vera family uses minimal delta hinting. Your |
|
||||||
results on other systems when not used anti-aliased may not be |
|
||||||
entirely satisfying. We are primarily interested in reports of |
|
||||||
problems on open source systems implementing Xft2/fontconfig/freetype |
|
||||||
(which implements antialiasing and hinting adjustements, and |
|
||||||
sophisticated subpixel decimation on flatpanels). Also, the |
|
||||||
algorithms used by Xft2 adjust the hints to integer widths and the |
|
||||||
results are crisper on open source systems than on Windows or |
|
||||||
MacIntosh. |
|
||||||
|
|
||||||
* Your fontconfig may (probably does) predate the release of |
|
||||||
fontconfig 2.2, and you may see artifacts not present when the font is |
|
||||||
used at very small sizes with hinting enabled. "vc-list -V" can be |
|
||||||
used to see what version you have installed. |
|
||||||
|
|
||||||
We believe and hope that these fonts will resolve the problems |
|
||||||
reported during beta test. The largest change is the reduction of |
|
||||||
leading (interline spacing), which had annoyed a number of people, and |
|
||||||
reduced Vera's utility for some applcations. The Vera monospace font |
|
||||||
should also now make '0' and 'O' and '1' and 'l' more clearly |
|
||||||
distinguishable. |
|
||||||
|
|
||||||
The version of these fonts is version 1.10. Fontconfig should be |
|
||||||
choosing the new version of the fonts if both the released fonts and |
|
||||||
beta test fonts are installed (though please discard them: they have |
|
||||||
names of form tt20[1-12]gn.ttf). Note that older versions of |
|
||||||
fontconfig sometimes did not rebuild their cache correctly when new |
|
||||||
fonts are installed: please upgrade to fontconfig 2.2. "fc-cache -f" |
|
||||||
can be used to force rebuilding fontconfig's cache files. |
|
||||||
|
|
||||||
If you note problems, please send them to fonts at gnome dot org, with |
|
||||||
exactly which face and size and unicode point you observe the problem |
|
||||||
at. The xfd utility from XFree86 CVS may be useful for this (e.g. "xfd |
|
||||||
-fa sans"). A possibly more useful program to examine fonts at a |
|
||||||
variety of sizes is the "waterfall" program found in Keith Packard's |
|
||||||
CVS. |
|
||||||
|
|
||||||
$ cvs -d :pserver:anoncvs@keithp.com:/local/src/CVS login |
|
||||||
Logging in to :pserver:anoncvs@keithp.com:2401/local/src/CVS |
|
||||||
CVS password: <hit return> |
|
||||||
$ cvs -d :pserver:anoncvs@keithp.com:/local/src/CVS co waterfall |
|
||||||
$ cd waterfall |
|
||||||
$ xmkmf -a |
|
||||||
$ make |
|
||||||
# make install |
|
||||||
# make install.man |
|
||||||
|
|
||||||
Again, please make sure you are running an up-to-date freetype, and |
|
||||||
that you are only examining integer sizes. |
|
||||||
|
|
||||||
