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 centered. 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 the OCR (optical character recognition) and the thumbnails, which can be loaded into the image viewer with a simple click of the mouse. See Figure 22.1: “The Kooka Main Window”.

Selecting ‘Show Scan Parameters’ in the ‘Tool Views’ subentry of the ‘Settings’ menu creates a third tab labeled ‘Scan Parameter’ next to the already existing ‘Image Viewer’ and ‘Scan Preview’ tabs in the main window. This is where the actual scanning parameters are set.
