Usage

You can run the program by typing gazou in your terminal. It runs in the background and should appear in your system tray. If you click on the app in the tray, a settings dialog should appear. In here, you can customize the keybinds to your liking. The default hotkeys are

Alt+A: Vertical OCR
Alt+D: Horizontal OCR
Alt+S: Repeat the previous OCR

When you perform an OCR, the result text gets copied to the clipboard.

Gazou also has a command line mode, and this can be useful for integrating it with bash scripts. It takes two different parameters, the image path and the orientation, which is either vertical (-v) or horizontal (-h). Here's an example:

gazou -h page103.png

This command scans all the text in the image and prints the resulting text.
