How to use trained data with pytesseract?

问题

Using this tool http://trainyourtesseract.com/ I would like to be able to use new fonts with pytesseract. the tool give me a file called *.traineddata

Right now I'm using this simple script :

try:
    import Image
except ImportError:
    from PIL import Image
import pytesseract as tes

results = tes.image_to_string(Image.open('./test.jpg'),boxes=True)
file = open('parsing.text','a')
file.write(results)
print(results)

How to I use my traineddata file so I'm able to read new font with the python script ?

thanks !

edit#1 : so I understand that *.traineddata can be used with Tesseract as a command-line program. so my question still the same, how do I use traineddata with python ?

edit#2 : the answer to my question is here How to access the command line for Tesseract from Python?

回答1:

Below is a sample of pytesseract.image_to_string() with options.

pytesseract.image_to_string(Image.open("./imagesStackoverflow/xyz-small-gray.png"),
                                  lang="eng",boxes=False,
                                  config="--psm 4 --oem 3 
                                  -c tessedit_char_whitelist=-01234567890XYZ:"))

To use your own trained language data, just replace "eng" in lang="eng" with you language name(.traineddata).
