libLASi is a library written by Larry Siden that provides a C++ stream output interface
( with operator << ) for creating Postscript documents that can
contain characters from multiple languages, as well as the full range of scientific
and other symbols defined in the
Unicode standard.
The library accomodates both left-to-right (e.g. most European
languages) as well as right-to-left scripts (e.g. Yiddish and Semitic languages),
even in the same document, without need for any special configuration
or layout calculation on the programmer's part.
Although the capability to produce Unicode-based multilingual Postscript documents
exists in large Open Source application framework libraries such as
GTK+,
QT, and
KDE,
libLASi was designed for projects which require
the ability to produce Postscript independent of any one application framework.

Motivation and Strategy
Download
In order to run the example program,
you may need to download and install the following
Hebrew font.
You may find this
HOWTO excerpt
helpful for installing Truetype fonts on Linux.
Prerequisites
- Pango 1.0+
- FreeType 2.1+
- Glib 2.0+
Documentation and help
To generate documentation for all interfaces including internals,
make "developer-docs".
The short program ./example/example.cpp
is meant as an example of how to use LASi.
The associated Makefile in the same directory demonstrates for programmers
how to build projects that include LASi.

Colophon
My friend, Ed Trager, who first envisioned and motivated me to write LASi,
suggested that I assign the name "Lasi" to this project,
as "Lasi" is composed of the first two letters of my first name, Larry,
followed by the first two letters of my last name, Siden.
Since this immediately delighted by own sense of vanity,
I had no trouble indulging Ed.
Out of concern that the name "Lasi" might invite ridicule
by jeolous software developer rivals
who would no doubt take every opportunity to mock it's connection
to the beloved TV canine hero,
I changed it's spelling to the post-modern, hi-tech moniker "LASi".
