For installation instructions, please see the file INSTALL
This package provides Eikazo, a graphical frontend for Sane, which
is intended mainly for usage with ADF scanners. It has one major
goal: to be fast.
Features:
- To maximize throughput for ADF scanners, a new scan is started
immediately after a scan has been finished. Postprocessing and
saving of the old scan is done, while the new scan is running.
- more than one output per scan possible: You can simultaneously save
the scanned image into a file and send it to a printer.
- plugin mechanisms for special devices features, for post-scan image
processing and for other "storage options".
The device plugin mechanism allows to implement functions to support
special device features.
With image enhancement plugins you can automatically post-process
the image. Currently, three plugins exist:
o adaptive threshold
o "dirt removal"
o ImageMagick
The combination of adaptive threshold and dirt removal can give better
scan results for "problematic" originals, for example, if you want to
extract the text from a paper with "shaded background", from an
stained original, or if you can't reliably predict the density of the
ink of the text. See the sample images samples/1.tif (simple fixed
threshold, set in the scanner), samples/2.tif ("automatic threshold" from
another scanner), samples/3.tif (grayscale scan) and samples/4.tif
(adaptive threshold).
The ImageMagick plugin is probably not very useful in many cases;
some of the provided options are procesed _very_ slow -- in short:
it is mostly intended to show how to integrate an external image
filter than to be directly useful.
Eikazo has at present three output plugins:
- write to file. supported file formats: TIFF and JPEG
- print
- write to file and record some informations about the scans in an
SQL database. This plugin is probably not very useful by itself --
what information abouts scans should be stored in a database,
depends on specific use cases. The plugin is mainly intended to be
an example that shows how Eikazo can be extended. It is by default
disabled in order to keep the user interface simple. If you want to
try the plugin, run eikazo with the environment variable
EIKAZO_SQLSAMPLE set to 1.
The plugin supports MySQL and PostgreSQL.
