SERVER CLIENT METHODS
The scanner consists of two halves - the server and the client. Both of these entities can
be located on a single machine, or spread over multiple machines.
THE FILTER SYSTEM
Rather than produce a monolithic application, the scanner consists of a number of discrete
programs and scripts that output files. The output file from one filter acts as the input file of another filter.
Each application produces
THE CONTROL SCRIPT
Filters are linked together in a particular order using a script called a control script. This makes it easy to
adapt the scanner to different purposes, and also to write a cross-platform GUI in HTML/PHP.
