Abstract

Kooka is a KDE application for scanning. This chapter explains the user interface and the functionality of the application. In addition to creating image files from printed media, like photographs or magazines, Kooka has character recognition capabilities. This means it can help convert written text to a text file that can be edited.

Start Kooka from the main menu or enter the command kooka. When started, Kooka opens a three-frame window with a menu bar to the upper left and a toolbar directly below it. All windows can be freely readjusted or rearranged with the mouse. It is also possible to completely detach single frames from the Kooka window for deliberate placement on the desktop. To move the frames, click and drag the thin double line right above the frame. Any frame, except the main window, can be placed within any other frame aligned to the left, right, top, bottom, or center. Centered windows have the same size, are stacked, and can be brought to the foreground with tabs.

The Image Viewer and the Scan Preview frames share a window by default. Tabs allow switching between them. The left frame provides the gallery. This is a small file browser for accessing the scanned images. The frame to the lower right is shared by OCR (optical character recognition) and the thumbnails, which can be loaded into the image viewer with a simple click of the mouse. See Figure 17.1, “The Kooka Main Window”.

17.1. The Preview

A preview should always be created when the object to scan is smaller than the total scanning area. Set a few parameters to the left of the preview frame. Select the scanning size with Custom or one of the standard formats. See Figure 17.2, “The Kooka Preview Window”. The Custom setting is the most flexible, because it allows selection of the desired area with the mouse. Once the settings have been made, request the preview of the image to scan by clicking Preview Scan in Scan Parameters.
