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:

  • adaptive threshold
  • "dirt removal"
  • 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.
