Python interface to the Tesseract library

Project description

A Python API for Tesseract

Requirements

  • Python >= 2.7 or >= 3.2
  • NumPy >= 1.6
  • Tesseract >= 3.02

Building

It’s the usual distutils dance – run python setup.py for more details.

If your Tesseract installation’s files are not in the standard system paths, you may need to create a setup.cfg with the following contents:

[build_ext]
include-dirs=/path/to/tesseract/include
library-dirs=/path/to/tesseract/lib

Example

Here’s a simple example that requires OpenCV:

import cv2
import tesserpy

tess = tesserpy.Tesseract("/path/to/tessdata/prefix", language="eng")
# Anything exposed by SetVariable / GetVariableAsString is an attribute
tess.tessedit_char_whitelist = """'"!@#$%^&*()_+-=[]{};,.<>/?`~abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789""""
image = cv2.imread('/path/to/image.png')
tess.set_image(image)
page_info = tess.orientation()
print(page_info.textline_order == tesserpy.TEXTLINE_ORDER_TOP_TO_BOTTOM)
print("#####")
print(tess.get_utf8_text())
print("#####")
print("Word\tConfidence\tBounding box coordinates")
for word in tess.words():
       bb = word.bounding_box
       print("{}\t{}\tt:{}; l:{}; r:{}; b:{}".format(word.text, word.confidence, bb.top, bb.left, bb.right, bb.bottom))
