Kooka, part of the kdegraphics package, is a
raster image scan program which supports OCR. It
is based on the scanner access library SANE. It
supports scanning in different modes and
resolutions, preview, scan area selection, and an
image save assistant which features a gallery
organised in a treeview with a comfortable image
viewer and thumbnail support. OCR is supported
through GOCR, an open source project. Kooka uses
the libkscan, which offers scanner support to all
KDE applications.
