The Main Window
The Main Window
Start from a console by simply entering kooka. Create a link on the desktop, which uses a scanner icon, if desired.
The main window in consists of three frames. At the top, see both icon and a menu panels. Use the mouse to enlarge or reduce the windows as needed.
The navigation window consists of two tabs, which allow you to switch between the Preview and the integrated file browser called the Gallery. The working directory is displayed in the lower part of the window along with the directory where the scan will be saved.
Make your scanner-dependent settings, which are dependent on the scanner you have connected, in the lower left window. Usually, these are settings for resolution, brightness and contrast, scanning mode (⪚, color, gray, or binary), and for gamma values.
Configure your settings here first. Afterwards, initiate the preview scan with Preview. If the Preview tab in the upper window is selected, see the results there.
Select the various formats in the preview image itself to define the final dimensions. The User setting is recommended for this, so you select the area to scan in the preview display with the mouse.
After this is done, click Scan to scan the selection made in the preview. After scanning, you will be asked in which format to save the image whether to make this your standard format (without being prompted to confirm your selection in the future).
If you checked that you do not want to be asked about the save format, the memory assistant will no longer appear. To change the format some time in the future, select Settings Configure Kooka... Save Image Always show memory assistant
The large window shows how the image appears after a final scan.
