tessbind 0.16.0

Tesseract pybind11 bindings

tessbind

Python 3.12+ bindings for Tesseract built with pybind11. The package vendors the native dependencies (leptonica, libpng, zlib) so you only need Tesseract's trained data files available at runtime.

Installation

pip install tessbind

Tesseract language data must be discoverable. If it is not installed in a default location (e.g., /usr/share/tesseract-ocr/5/tessdata on Linux or the Homebrew Cellar on macOS), set TESSDATA_PREFIX to the directory that contains the tessdata folder.

Usage

TessbindManager wraps the underlying API in a context manager and exposes the recognized UTF-8 text plus per-word confidences:

from pathlib import Path

from tessbind import PageSegMode, TessbindManager

img_bytes = Path("tests/hello.png").read_bytes()

with TessbindManager(lang="eng", page_seg_mode=PageSegMode.SINGLE_LINE) as tb:
    text, confidences = tb.ocr_image_bytes(img_bytes)

print(text)         # -> Hello, World!
print(confidences)  # list of word-level confidences (0-100)

Use the page_seg_mode setter to change segmentation between calls, or omit it to rely on Tesseract's default.

Development

• uv sync --extra test to create the venv and build vendored libraries.
• uv run pytest -m "not slow" to run the test suite.
