Image libraries
---------------

These precompiled image libraries are required when compiling the
source code for several applications. In partucular:

!Snapper requires to be linked to the jpeg9d library, preferably the
jpeg9d_fl version, which provides flex memory handling functions. It
also requires the PNG and Zlib libraries for saving as PNG. The Zlib
library is required by the PNG librariy to provide
compression/decompression functions.

!DPlngScan requires the jpeg9d_fl, PNG and Zlib libraries as above. It
also requires the Tiff library for the Tiff image format, and the
TWAIN library for the scanning capability.
