Sorry, there seems to be a problem with the fixed pitch detector. I haven't had chance to investigate it completely yet, and I don't remember exactly, but it is possible that the fixed pitch detector doesn't work on modern fixed pitch. On old typewriters, the spaces are the same size as the characters, but on modern (word processed/laser or inkjet printed) fixed pitch, the size of the spaces is variable, and this is probably preventing the fixed pitch detection algorithm form seeing the text as fixed pitch. Font size can be calculated as follows: ROW* row = ...; double pt_size = (row->x_height() + row->ascenders() - row->descenders()) * 72.0 / resolution; Where row can be obtained from a ROW_RES, and reolution is the input resolution of the image. See write_shm_text in output.cpp.
