• Recognize characters in the [i]nput image and [o]utput it in the given file. Put the database ([p]) in path/to/db_directory (verify that the folder exists or DB usage will silently be skipped). [m]ode 130 means create + use + extend database:

gocr -m 130 -p {{path/to/db_directory}} -i {{path/to/input_image.png}} -o {{path/to/output_file.txt}}

gocr -m 130 -p {{path/to/db_directory}} -i {{path/to/input_image.png}} -o {{path/to/output_file.txt}} -C "{{0..9}}"

gocr -m 130 -p {{path/to/db_directory}} -i {{path/to/input_image.png}} -o {{path/to/output_file.txt}} -a 100
