Development: Embedded Graphics Part I
appears in the July 1999 issue of Embedded
Systems Programming magazine.
It discusses fonts
and bitmaps for embedded systems. The code related to the article
is available for download here. It is
in ZIP format. If you require another format, or have any comments
to make on the article, then E-mail
A character editor,
for fixed sized fonts, is available from http://www.bluewind.it/products.html
Another handy tool
is this bdfviewer.zip for Windows.
It was kindly contributed by the guys at Mars Electronics. It
is useful for taking a quick look at what a BDF font will look
like if you do not have an environment, such as Linux, where you
can install the font. Unfortunately limited to single-byte fonts
and so will not read unicode fonts.

A related library,
which is not mentioned in the article is the Jpeg library, libJpeg,

ERRATA The location
of the BDF Specification document referred to in the article has
changed since the magazine went to print and adobe also require
registration, so an easier source is :http://ftp.ktug.or.kr/obsolete/info/adobe/devtechnotes/pdffiles/5005.bdf_spec.pdf
Sites for finding fonts
in the BDF format:
I am looking for a
good link to a self contained windows ttf to bdf converter, but
have still not located one. A search for ttf2bdf will yield some
which can be built for X11 environments.
The August issue contains
II which discusses the use of objects in graphics software,
and algorithms for updating the display.

articles have given you an appetite for more, then check out my
