Question

Could you please specify how to recognize the PNG document in CommandLineInterface in FineReader Engine 12 for Linux?

Answer

The available settings for the CommandLineInterface sample are mentioned in CmdLineOptions.cpp file at /opt/ABBYY/FREngine12/Samples/CommandLineInterface

Detailed documentation of those settings with its explanation is available by default at /opt/ABBYY/FREngine12/Help/HTML/index.html

For example:

./CommandLineInterface -pi -if /data/abbyy_install/nu_colour.png -f PDF -lpp "TextExtraction_Accuracy" -of /data/abbyy_install/nu_colour.converted.pdf
