How to find parameters supported in Tesseract OCR config file
tesseract
Solution
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
Problem
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. How can I determine what parameters are supported, and what they mean?
