xcam(1)                DragonFly General Commands Manual               xcam(1)


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 invidual 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) xcam flag prints a short summary of options.

       SANE_DEBUG_XCAM
              This environment variable controls the debug level xscanimage.
              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.
