How to find parameters supported in Tesseract OCR config file

Question

I want to know what parameters the config file used by Tesseract OCR accepts, how to write a config file, etc.

I can\'t find any documentation about this on their site.

Answer 1

Tesseract v3.04 now offers the command line option --print-parameters, so you can call tesseract --print-parameters to get a list of the 678 (!) configurable parameters, their default values, and a short description:

Tesseract parameters:
editor_image_xpos   590 Editor image X Pos
editor_image_ypos   10  Editor image Y Pos
editor_image_menuheight 50  Add to image height for menu bar
editor_image_word_bb_color  7   Word bounding box colour
editor_image_blob_bb_color  4   Blob bounding box colour
editor_image_text_color 2   Correct text colour
...and many, many more
