NAME

       xcam - a graphical camera frontend for SANE

SYNOPSIS

       xcam [--buffer|-B] [--version|-V] [--help|-h]

DESCRIPTION

       xcam  provides a graphical user-interface to control an image acquisition device such as a
       flatbed scanner or a camera.  It allows scanning individual  images  and  can  be  invoked
       directly from the command-line.

       xcam  acts  as  a  stand-alone program that saves acquired images in a suitable PNM format
       (PBM for black-and-white images, PGM for grayscale images, and PPM for color images).

       xcam accesses image acquisition  devices  through  the  SANE  (Scanner  Access  Now  Easy)
       interface.  The list of available devices depends on installed hardware and configuration.

       xcam presents a menu listing of all known and available devices.

OPTIONS

       If  the  --Buffer (-B) option is given, xcam will use a 1024 kByte input buffer instead of
       the default 32 kByte.

       If the --version (-V) option is given, xcam will output its version number.

       The --help (-h) flag prints a short summary of options.

       SANE_DEBUG_XCAM
              This environment variable controls the debug level of xcam.   Higher  debug  levels
              increase the verbosity of the output.

                            Value  Descsription
                            0      print fatal errors
                            1      print errors
                            2      print warnings
                            3      print information messages
                            4      print everything

                            Example:
                            SANE_DEBUG_XCAM=3

FILES

       $HOME/.sane/xcam/devicename.rc
              For  each  device,  there  is  one  rc-file  that holds the saved settings for that
              particular device.   Normally,  this  file  should  not  be  manipulated  directly.
              Instead,  the  user  should use the xcam interface to select appropriate values and
              then save the device settings using the  "Preferences->Save  as  default  settings"
              menubar entry.
