[JP T]

Hi

I just updated from version 3.04.01 but now tesseract fails with above message if I give the -psm option.
input files are PNG.

any idea?

thanks

Use

--psm

as --psm is deprecated

If you are really insterested in help than provide full information/command how you run tesseract.

Solved:
must be tesseract infile outfile options instead of standard unix program options infile outfile.

... and it was exactly the same in tesseract 3.0x as in 4.0....

Well, the problem is error handling.
If tesseract would have given a meaningful error message...
This is about basic parameter handling, nothing sophisticated.

aim is to have tool that is easy portable with minimum dependencies.

IMO it is standard on linux/unix like system to use --help option for explanation of usage.
