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 PPM pixmap files).  The purpose of this backend is primarly to aid in debugging  of  SANE  fron-
       tends.  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

       SANE_DEBUG_PNM
	      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.

NAME

       sane-nec - SANE backend for NEC scanners

DESCRIPTION

       The sane-nec library implements a SANE (Scanner Access Now Easy) backend that provides access to NEC SCSI scanners.  This backend should be
       considered alpha-quality software!  In the current state it is known to work with PC-IN500/4C scanners. Another MultiReader scanner  series
       is not supported. PC-IN 500/4C and MultiReader scanner are only sold in Japan.(except Multi Reader PetiScan.)

       For other scanners, it may or may not work.

       The backend has the following known problems:
	      - ColorLineart mode is not supported.
	      - device name is fixed to /dev/scanner

       At present, the following scanners are known to work with this backend.
	      Vendor Product id
	      ------ -----------
	      NEC    PC-IN500/4C

FILES

       /etc/sane.d/nec.conf
	      The backend configuration file.

       /usr/lib64/sane/libsane-nec.a
	      The static library implementing this backend.

       /usr/lib64/sane/libsane-nec.so
	      The shared library implementing this backend (present on systems that support dynamic loading).

ENVIRONMENT

       SANE_DEBUG_NEC
	      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.
