Example:23python -c '24import eyenfinger25eyenfinger.printEventsFromFile("/dev/input/event0")26'27Alternatively, you can use device names in /proc/bus/input/devices and28printEventsFromDevice("device name").29Configuring OCR30---------------31autoconfigure() evaluates number of preprocessing filters to give the32best result on finding given words from given image. Example:33python -c '34from eyenfinger import *35autoconfigure("screenshot.png", ["Try", "to", "find", "these", "words"])36'37evaluatePreprocessFilter() highlights words detected on given image. Example:38python -c '39from eyenfinger import *40evaluatePreprocessFilter("screenshot.png", "-sharpen 5 -resize 1600x", ["File", "View"])41'42setPreprocessFilter() sets given filter to be used when reading text from images.43Debugging44---------45iClickWord() capture parameter visualises coordinates to be clicked.
