  44 \begin{abstract}
  45 SANE is an open source project to provide scanner support on Unix.  It
  46 supports more then 200 different scanners and works on almost all Unix
  47 platforms.

  54 \heading{What is SANE}
  55
  56 \begin{itemize}
  57
  58 \item Open Source multi-platform project with developers all over the
  59   world.
  60
  61 \item Application programming interface (API) that provides
  62   standardized access to any raster image scanner hardware (flatbed
  63   scanner, hand-held scanner, video- and still-cameras,
  64   frame-grabbers, etc.).
  65
  66 \item Network protocol to communicate with scanner servers --- hosts
  67   with attached scanner hardware.

  75 \heading{Why another scanner API}
  76
  77 When the SANE project started, there were no common scanner API on
  78 Unix.  Some programs supported some scanners, but every program
  79 maintained it's own drivers.
  80
  81 TWAIN existed only on Windows and Macintosh.  The TWAIN API is not
  82 usable, because GUI and scanner driver is one (i.e. platform
  83 dependent) and it has no network support.

  90 \begin{itemize}
  91
  92 \item automated and remotely controllable semiconductor inspection
  93   microscopes
  94
  95 \item lets MEMS designers view their wafers after critical processing
  96   steps from any location having an Internet connection.

 101
 102 \begin{itemize}
 103
 104 \item an optical microscope (currently a Leica INM200 or
 105 INS1000)
 106
 107 \item a server which controls the microscope
 108
 109 \item a JavaTM applet or servlet that constructs the client interface.

 119
 120  \item Frontend is backend and platforms independent
 121
 122  \item Backends are platform independent
 123
 124  \item The sane internal (sanei) API hides all platform dependent code
 125    (SCSI, parport, serial, network and config file API) from the
 126    backends.

 132 \heading{Setting up SANE}
 133 \subsection*{Fetch and compile}
 134
 135 Download latest distribution from \url{http://www.mostang.com/sane/},
 136 current stable version is 1.0.2.
 137
 138 Unpack:\\
 139 {\tt tar zxvf sane-<version>.tar.gz}
 140
 141 Compile:\\
 142 {\tt ./configure <--prefix=[/usr/local]>\\
 143 make; make install}.
 144
 145 When successful, {\tt scanimage}, {\tt xscanimage}, {\tt xcam}, {\tt
 146   sane-config} should be available in /usr/local/bin;.
 147
 148 {\tt xscanimage} require the Gtk library and might be missing.
 149
 150 \newslide
 151
 152 \subsection*{Configuration}
 153
 154 The SANE config files hide in {\tt <prefix>/etc/sane.d/}.
 155
 156 \begin{itemize}
 157   \item local scanner
 158     \begin{itemize}
 159       \item {\tt dll.conf} \\
 160         List of backends to load.  Comment out the unused ones to
 161         reduce startup time. ('man sane-dll' for details)
 162       \item {\tt $<$backend$>$.conf} \\
 163         Backend-dependent configuration, normally path to scanner device.
 164       \item Test with {\tt scanimage -L} and {\tt scanimage -T}
 165       \item If nothing works, try to set environment
 166         {\tt SANE\_DEBUG\_DLL=128} to get debug information.
 167     \end{itemize}
 168 \newslide
 169   \item network scanner
 170     \begin{itemize}
 171       \item {\tt /etc/inetd.conf} and {\tt /etc/services} (server side)
 172         to start saned. ('man saned' for details)
 173       \item {\tt saned.conf} (server side)\\
 174         List of hosts allowed to access scanner.  Insert '+' to allow
 175         everyone and leave access control to tcp\_wrapper.
 176       \item {\tt net.conf} (client side)\\
 177         List of scanner server hosts to contact.
 178       \end{itemize}

 184 \heading{Frontends}
 185
 186 I'm aware of the following applications with SANE support.
 187
 188 \begin{itemize}
 189  \item {\tt scanimage} for batch scanning
 190  \item {\tt xscanimage} / {\tt xsane} for GUI. (also as GIMP plugins)
 191  \item WWW frontend (SANEcgi)
 192  \item Pyton and Tcl/Tk client
 193  \item NextStep client (NSane)
 194  \item BeOS client
 195  \item OS/2 client (ScanIt/2)
 196  \item winsane / xsane for Windows
 197 \end{itemize}
 198
 199 {\tt xsane} is the best client for Unix/X11 at the moment.

 203 \heading{Supported scanners and platforms}
 204 \begin{itemize}
 205  \item 35 backends and $>200$ different models
 206  \item Mostly SCSI, some parallel port and some USB scanners
 207
 208  \item Works on Unix (Linux, *BSD, HP/UX, OpenSTEP, DEC Unix, SCO *,
 209    Irix, Solaris, AUX, DomainOS), OS/2, BeOS and sometimes even on
 210    Windows.
