SANE Scanner Access Now Easy                          sane-pnm(5)



NAME
     sane-pnm - SANE PNM image reader pseudo-backend

DESCRIPTION
     The sane-pnm library implements a SANE (Scanner  Access  Now
     Easy)  backend  that provides access to PNM (Portable aNyMap
     files, which covers PBM bitmap files, PGM  grayscale  files,
     and  PM pixmap files).  The purpose of this backend is pri-
     marly to aid in debugging of SANE frontends.  It also serves
     as an illustrative example of a minimal SANE backend.

DEVICE NAMES
     This backend provides two devices called 0 and 1.

CONFIGURATION
     No configuration required.

FILES
     /usr/lib/sane/libsane-pnm.a
          The static library implementing this backend.

     /usr/lib/sane/libsane-pnm.so
          The shared library implementing this  backend  (present
          on systems that support dynamic loading).

ENVIRONMENT
     SANEDEBUGPNM
          If the library was compiled with debug support enabled,
          this  environment variable controls the debug level for
          this backend.  E.g., a value of 128 requests all  debug
          output to be printed.  Smaller levels reduce verbosity.

BUGS
     If the pnm backend is installed and saned is used  to  allow
     users  on remote computers to scan on the local machine, pnm
     files can be read by the remote user. This is limited to the
     files  saned  can  access  (usually  it's  running  as  user
     "sane"). All pnm files can be read if  saned  runs  as  root
     which  isn't recommended anyway. The pnm backend is disabled
     by default. If you want to use it, enable it with  configure
     (see  configure  --help  for  details).  Be  sure  that only
     trusted users can access the pnm backend over saned.
