Introduction
\layout Standard

Bitstream Vera was designed by Jim Lyles of Bitstream, Inc., in cooperation
 with the Gnome Foundation as a high quality scalable free font for use
 with free open-source software 
\begin_inset LatexCommand \cite{vera}

\end_inset 

.
 The Bitstream Vera family includes serif, sans serif, and monospaced fonts,
\begin_inset Foot

\layout Standard

The text of this document is set in Bera Serif and Mono\SpecialChar ~

\begin_inset LatexCommand \cite{bera}

\end_inset 

, a repackaging of Bitstream Vera for TeX.
\end_inset 

 and all three fonts have normal, oblique, bold, and bold oblique faces.
 Bitstream Vera is primarily intended as a screen font (though it also works
 well as a print font) and has hinting for display on low-resolution devices
 such as computer monitors and projectors.
 All three fonts have large 
\emph on 
x
\emph default 
 height, wide letters and spacing, and 
\begin_inset Quotes eld

\begin_inset Quotes erd
\end_inset 

 letters,
\begin_inset Foot

\layout Standard

For instance, compare the lowercase 
\begin_inset Quotes eld
\end_inset 

e

\end_inset 

 of Arev Sans with that of Helvetica.
\end_inset 

 resulting in fonts that are extremely easy to read at small sizes or on
 projected displays.
 
\layout Standard

Tavmjong Bah created Arev Sans
\begin_inset Foot
collapsed true

\layout Standard

Per the license for Bitstream Vera, any derivative fonts must have a different
 name.
\end_inset 

 by extending Bitstream Vera Sans to include Greek, Cyrillic, and many mathemati
cal symbols 
\begin_inset LatexCommand \cite{arev}

\end_inset 

.
 The new glyphs added by Bah accurately capture the feel of the Latin letters
 and so seamlessly integrate into the font.
 Bah's intention was to add symbols that are useful for technical writing,
 and hence the Greek letters are typical of those used in mathematics and
 science and not of the letters used in writing the Greek language.
\begin_inset Foot

\layout Standard

Specifically, alpha is not the same as lowercase 
\begin_inset Quotes eld
\end_inset 

a,
\begin_inset Quotes erd
\end_inset 

 nu is not the same as lowercase 
\begin_inset Quotes eld
\end_inset 

v,
\begin_inset Quotes erd
\end_inset 

 and Upsilon is not the same as uppercase 
\begin_inset Quotes eld
\end_inset 

Y.
\begin_inset Quotes erd
\end_inset 


\end_inset 

 At the author's request, Bah also added several alternate glyphs for some
 of the Latin and Greek letters.
 This was mainly done so that all of the letters can be clearly distinguished
 when in mathematics and not surrounded by other letters or even aligned
 with the baseline.
\begin_inset Foot

\layout Standard

The lowercase 
\begin_inset Quotes eld
\end_inset 

l
\begin_inset Quotes erd
\end_inset 

 and the uppercase 
\begin_inset Quotes eld
\end_inset 

I
\begin_inset Quotes erd
\end_inset 

 in particular are almost identical in Bitstream Vera Sans.
 The lowercase phi and original uppercase Phi in Arev Sans are also difficult
 to distinguish without a baseline.
\end_inset 

 Additionally, several alternate glyphs were added that are 
\begin_inset Quotes eld
\end_inset 

warmer
\begin_inset Quotes erd
\end_inset 

 or more 
\begin_inset Quotes eld
\end_inset 

humanist

 than the strict

\end_inset 

geometric

 glyphs.
\begin_inset Foot

The extra glyphs include

i,

 and uppercase Pi and Phi.
 The florin is used as an alternate 
\begin_inset Quotes eld
\end_inset 

f.
\begin_inset Quotes erd
\end_inset 


\end_inset 

 These extra glyphs add a degree of warmth to mathematics written in Arev
 Sans that is not achieved with other sans serif fonts.

Figure\SpecialChar ~

 shows a sample of Arev Sans being used for text and mathematics.
 The primary use that the author sees for Arev Sans in LaTeX is for presentation
s, and especially for those that are displayed with a computer projector.
 The attributes of Bitstream Vera and Arev mentioned above make Arev particularl
y suited for this purpose.
 Besides Arev, there are only a few other options for sans serif fonts in
 LaTeX, and none of them are entirely satisfactory.
 Computer Modern sans serif and the SliTeX sans serif
\begin_inset Foot
collapsed true

\layout Standard

Arev Sans is actually very similar to SliTeX sans serif (
\family typewriter 
lcmss
\family default 
) in that both have large 
\emph on 
x
\emph default 
 height, have wide letters and spacing, and have 
\begin_inset Quotes eld
\end_inset 

open
\begin_inset Quotes erd
\end_inset 

 letters.
 Arev Sans is heavier than SliTeX sans serif though, which makes it more
 suitable for computer projectors.
\end_inset 

 fonts can be used for text, but Computer Modern roman is still used for
 mathematics.

Harald Halders created Type 1 Postcript font versions of the 
\family typewriter 
cmbright
\family default 
 fonts called 
\family typewriter 
hfbright
\family default 
.
 The fonts were created by tracing high resolution bitmaps, and so are not
 perfect.
 However, scalable Type 1 fonts greatly improve the quality of Postscript
 and 
\family typewriter 
.pdf
\family default 
 files on computer screens and projectors.
\end_inset 

 (
\family typewriter 
cmbright
\family default 

\begin_inset LatexCommand \cite{cmbright}

\end_inset 

) is a sans serif family that includes both text and mathematics, but is
 very thin and does not display well on a computer projector.
 Kerkis Sans
\begin_inset LatexCommand \cite{kerkis}

\end_inset 

 is based on Avant Garde and includes Greek sans serif glyphs, but is also
 very thin.
 Helvetica and other PostScript sans serif fonts can be used for text and
 for Latin letters in mathematics, but they do not have matching Greek letters
 or the proper weight for geometric mathematical symbols.

Implementation
\layout Standard

With internationalization of computer software and the growing use of Unicode,
 many free scalable fonts are available that include both Latin and Greek
 letters.
 However, making use of these fonts for mathematics in LaTeX is a nontrivial
 task: not only are there many subtleties to using fonts in LaTeX, but the
 documentation is scattered among many sources and there are few examples
 to consult.
 The author hopes that the 
\family typewriter 
arev
\family default 
 package can serve as a template for others who wish to create new math
 font packages for LaTeX.
\layout Standard

The excellent GPLed font editor FontForge\SpecialChar ~

\begin_inset LatexCommand \cite{fontforge}

\end_inset 

 was used by Bah to create Arev Sans and was used by the author for creating
 PostScript 
\family typewriter 
pfb
\family default 
, 
\family typewriter 
afm
\family default 
 , and TeX 
\family typewriter 
tfm
\family default 
 files.
 The Bash shell script 
\family typewriter 
afmtoglyphlist
\family default 
 was used to extract the glyph names from the 
\family typewriter 
afm
\family default 
 file into a list that a 
\family typewriter 
fontinst
\family default 
 script used for renaming glyphs.
 The magic of 
\family typewriter 
fontinst
\family default 
 was used to create virtual fonts and font metrics, LaTeX font definition
 files, and the 
\family typewriter 
dvips
\family default 
 map file.
\layout Standard

The vertical placement of math accents requires the accents to be appropriately
 placed for characters 1 ex high.
 The accents also need to have a zero depth, which is set by the file 
\family typewriter 
fixot1accents.mtx
\family default 
 (based on their bounding boxes, the accents naturally have negative depths).
 Horizontal placement of math accents is done by centering the accent over
 the character, and then adjusting the position by the kern between the
 character on the left and a special character called the 
\emph on 
skewchar
\emph default 
.
 To better visualize the placement of the accents, the graphical kerning
 dialog box in FontForge was used, and then the script 
\family typewriter 
afmtokernaccent
\family default 
 extracts this kern information from the 
\family typewriter 
afm
\family default 
 file and creates 
\family typewriter 
mtx
\family default 
 files that calculate the appropriate kern.
 The one difficulty in implementing this in 
\family typewriter 
fontinst
\family default 
 is that the kerning data must be reglyphed before applied to the font metrics.
\layout Standard

Arev Sans is used for all letter-like symbols, including Latin and Greek
 letters.
 Arev Sans includes many mathematical symbols, but not the full range of
 symbols included in Computer Modern or the AMS symbol fonts.
 The Math Design Bitstream Charter\SpecialChar ~

\begin_inset LatexCommand \cite{mdch}

\end_inset 

 bold math font comes very close to the weight of Arev Sans, and so is used
 for the majority of geometric symbols
\begin_inset Foot
collapsed true

\layout Standard

The Math Design Bitstream Charter math fonts have a few minor flaws: for
 instance, in the formation of square root symbols and overbraces.
 However, most of the symbols are of fine quality, and the range of symbols
 is impressive.
\end_inset 

.
 Computer Modern is used for the default calligraphic font, Fourier-GUTenberg\SpecialChar ~

\begin_inset LatexCommand \cite{fourier}

\end_inset 

 for blackboard bold (since the letters are sans serif), Ralph Smith Formal
 Script for script, and the AMS font for fraktur.
 One disadvantage of using so many different fonts for mathematics is that
 TeX can only have sixteen simultaneously loaded fonts, and the Arev package
 comes very close to this limit.
\layout Standard

The file 
\family typewriter 
mathtesty.tex
\family default 
 is a combination of the file 
\family typewriter 
mathtestx.tex
\family default 
 from the 
\family typewriter 
mathptmx
\family default 
 package\SpecialChar ~

\begin_inset LatexCommand \cite{mathptmx}

\end_inset 

 and the 
\family typewriter 
symbols.tex
\family default 
 file of David Carlisle.
 It is very useful for testing all of the math styles and symbols for a
 given font setup.
\layout Standard

There are three LaTeX packages for use with Arev Sans: 
\family typewriter 
arev
\family default 
, 
\family typewriter 
arevtext
\family default 
, and 
\family typewriter 
arevmath
\family default 
.
 The 
\family typewriter 
arev
\family default 
 package simply loads both 
\family typewriter 
arevtext
\family default 
 and 
\family typewriter 
arevmath
\family default 
.
 
\family typewriter 
arevtext
\family default 
 changes the default text font (both roman and sans serif) to Arev Sans.
 
\family typewriter 
arevtext
\family default 
 also changes the default typewriter font to Bera Mono, a repackaging of
 Bitstream Vera Mono for TeX.
 
\family typewriter 
arevmath
\family default 
 sets the math fonts as described above.
 In addition to the normal styles, the 
\family typewriter 

\backslash 
mathbm
\family default 
 command changes the math font to bold italic.

 This would require modification of the variant letters code as well.

 However, Arev's creator Tavmjong Bah requests that TrueType versions of
 Arev be obtained from his website at

 LaTeX package.
 FontForge source files may also be obtained at his website.
