Taking fun
as simply fun
and earnestness
in earnest
shows how thoroughly
thou none
of the two
discernest.

This is Tom Powers' zip file that contains the entire 'lib'
and 'include' directories needed to build Windows-based programs
using static or dynamic versions of the leptonica library
(including static library versions of zlib, libpng, libjpeg,
libtiff, and giflib). The libraries are built with Microsoft
Visual Studio 2008 32-bit. See his developer package notes
for version details, including where to unzip this file.
Version 1.68: leptonica-1.68-win32-lib-include-dirs (3/14/11)

Version 1.66: leptonica-1.66-win32-lib-include-dirs (8/9/10)
leptonica-1.66-win32-lib-include-dirs.zip
Even if you're not going to develop applications using the
leptonica library on Windows, you may want to look
at the beautiful
vs2008 Developer Notes
that Tom constructed using Sphinx.
This is a self-contained package that extracts C prototypes from
C files. It was a fun exercise (see grook above) in building
a simple parser with the leptonica string array (Sarray) utility.
It is also included in the leptonica library.
Version 1.5 (5/15/11)
xtractlib-1.5.tar.gz
This is a self-contained package with a simple interface
to gnuplot, but with no other dependencies. It is also included
in the leptonica library.
Version 1.2 (3/24/07)
plotlib-1.2.tar.gz
