Re: [Jocr-devels] Bug - No contrast in image causes division by zero

[Igor F. [Contr] <ig...@he...>]

Dear Joerg,

I've tried building the libPgm2asc.a library in 0.47 (by the way - thank
you for adding it back), but no success so far. Attached is the output
of "make libs". Am I missing something obvious?

Thank you,
Igor
