NAME

       xscanimage - scan an image


SYNOPSIS

       xscanimage   [--version|-V]   [--help|-h]   [--display  d]  [--no-xshm]
       [--sync] [devicename]


DESCRIPTION

       xscanimage provides a graphical  user-interface  to  control  an  image
       acquisition  device  such  as a flatbed scanner or a camera.  It allows
       previewing and scanning invidual  images  and  can  be  invoked  either
       directly  from  the command-line or through The GIMP image manipulation
       program.  In the former case, xscanimage 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).   In
       the latter case, the images are directly passed to The GIMP for further
       processing.

       xscanimage accesses image acquisition devices through the SANE (Scanner
       Access  Now  Easy) interface.  The list of available devices depends on
       installed hardware and configuration.  When invoked without an explicit
       devicename  argument, xscanimage presents a dialog listing of all known
       and available devices. If the environment variable  SANE_DEFAULT_DEVICE
       is  set  to the devicename, the device is preselected in the dialog. To
       access an available device that is not known to the system, the device-
       name must be specified explicitly. The format of devicename is backend-
       name:devicefile (e.g. umax:/dev/sga).


RUNNING UNDER THE GIMP

       To run xscanimage under the gimp(1), simply  copy  it  to  one  of  the
       gimp(1)  plug-ins directories.  If you want to conserve disk-space, you
       can create a symlink instead.  For example, for gimp-1.0.x the command

       ln -s /usr/local/bin/xscanimage ~/.gimp/plug-ins/

       and for gimp-1.2.x the command

       ln -s /usr/local/bin/xscanimage ~/.gimp-1.2/plug-ins/

       adds a symlink for the xscanimage binary to the user's plug-ins  direc-
       tory.   After  creating  this  symlink,  xscanimage  will be queried by
       gimp(1) the next time it's invoked.  From then on,  xscanimage  can  be
       invoked   through  "File->Acquire->Xscanimage->Device  dialog..."  menu
       entry.

       You'll also find that  the  "File->Acquire->Xscanimage"  menu  contains
       short-cuts to the SANE devices that were available at the time xscanim-
       age was queried.  For example, the first PNM pseudo-device is typically
       available  as  the  short-cut "File->Acquire->Xscanimage->pnm:0".  Note
       that gimp(1) caches these short-cuts in ~/.gimp/pluginrc.   Thus,  when
       the  list  of  available  devices  changes  (e.g.,  a  new  scanner  is
       installed), then it is typically desirable to rebuild this  cache.   To
       do  this,  you  can either touch(1) the xscanimage binary (e.g., "touch
       /usr/local/bin/xscanimage") or delete the  plug-ins  cache  (e.g.,  "rm
       ~/.gimp/plug-ins").  Either way, invoking gimp(1) afterwards will cause
       the pluginrc to be rebuilt.


OPTIONS

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

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

       The  --display flag selects the X11 display used to present the graphi-
       cal user-interface (see X(1) for details).

       The --no-xshm flag requests not to use shared  memory  images.   Shared
       memory  images usually enhance performance but cause problems with some
       buggy X11 servers.  Unless your X11 server dies when running this  pro-
       gram, there is no need or advantage to specify this flag.

       The  --sync flag requests a synchronous connection with the X11 server.
       This is for debugging purposes only.


ENVIRONMENT

       SANE_DEFAULT_DEVICE
              The           default           device-name.            Example:
              SANE_DEFAULT_DEVICE="hp:/dev/scanner".

       SANE_DEBUG_XSCANIMAGE
              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_XSCANIMAGE=3


FILES

       $HOME/.sane/xscanimage/xscanimage.rc
              This files holds the  user  preferences.   Normally,  this  file
              should  not  be  manipulated directly.  Instead, the user should
              customize the program through the "Preferences" dialog.

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

       $HOME/.sane/preview-devicename.ppm
              After acquiring a preview, xscanimage normally saves the preview
              image in this device-specific file.  Thus, next time the program
              is  started  up,  the program can present the old preview image.
              This feature can be turned off through the "Preferences->Preview
              Options..." dialog.

       /usr/local/share/sane-style.rc
              This system-wide file controls the aspects of the user-interface
              such as colors and fonts.  It is a GTK style file  and  provides
              fine control over the visual aspects of the user-interface.

       $HOME/.sane/sane-style.rc
              This file serves the same purpose as the system-wide style file.
              If present, it takes precedence over the system wide style file.
