-c textord_min_linesize 3.25 in tesseract 4 give Errormessage

[Martin Jenniges]

Hello,

I have found the follow Tip for tesseract; but when I give this parameter with -c  textord_min_linesize 3.25 in tesseract 4, I receive a error message. What is wrong ?

Example 3: Line Size

Command

tesseract image.jpg outputfilename config

Command Line Arguments

None

Config Settings

textord_min_linesize 3.25

Notes

• textord_min_linesize seems to have an affect on the line heights detected by Tesseract when it performs the layout analysis on the image.  The default value for this setting is 1.25.
• When set to 3.25, the "broken" line problem in the original baseline output is corrected.  Lower settings (for example, 3.0) do not correct the "broken" lines.  
• This settings causes other character recognition errors.
• The text in the output that is highlighted in red is again correctly contained on a single line.
• The words highlighted in blue include extra characters that are a results of "noise" (specks and imperfections in the image).  None of these have corrected, but no new ones have appeared.
• Lines between "paragraphs" now appear in somewhat odd locations.  Again, there are NO lines between paragraphs on the source image.
• The garbage words at the end of the page do not appear.
• A small number of errors in individual words that appear in the original output were corrected, a few other incorrect words changed (but were still incorrect), a small number of correct words now are  incorrect.  These have been highlighted in purple.
