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 cam-
era. 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 configu-
ration. When invoked without an explicit devicename argu-
ment, 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 devicename 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 con-
serve disk-space, you can create a symlink instead. For
example, for gimp-1.0.x the command
ln -s /usr/bin/xscanimage ~/.gimp/plug-ins/
and for gimp-1.2.x the command
ln -s /usr/bin/xscanimage ~/.gimp-1.2/plug-ins/
adds a symlink for the xscanimage binary to the user's plug-
ins directory. 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->Xscan-
image->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 xscanimage 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/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 out-
put its version number.
The --help (-h) flag prints a short summary of options.
The --display flag selects the X11 display used to present
the graphical 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 program, 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
SunOS 5.11 Last change: 1 Feb 2003 2

file should not be manipulated directly. Instead, the
user should customize the program through the "Prefer-
ences" dialog.
$HOME/.sane/xscanimage/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 xscanimage interface to select
appropriate values and then save the device settings
using the "Preferences->Save Device Settings" 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/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.
