Hi Patrick, Do you have experience that it works (e.g. it produces different output for different "Page seg mode")?
I tried several options but I got the same output. I used scan of 4
column magazine page as input file.
Maybe I did something wrong, maybe I do not understand what should be
result...
I created new config file (/usr/local/share/tessdata/tessconfigs/PSM)
with line:
tessedit_pageseg_mode 3
and than I run:
$ /usr/local/bin/tesseract multicolumn.tif ouput_3 PSM
tesseract accepted config file (if I replace "3" with "PSM_SINGLE_LINE"
tesseract will complain that "variable not found: tessedit_pageseg_mode"
- there must be number as explain in ccmain/tesseractclass.cpp:
"Page seg mode: 0=auto, 1=col, 2=block, 3=line, 4=word, 6=char")
When I add to config file another line:
tessedit_dump_pageseg_images true
it produces the same images as input image even I use different "Page
seg mode..." (I expected that it will create different images for
different "Page seg mode")
