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 devicename must be
specified explicitly. The format of devicename is backendname: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/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->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
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 output 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 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 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.
