Verified usage

Verified import paths — ran on the pinned version, not inferred.

decode

✓ import pylibdmtx.pylibdmtx; decode = pylibdmtx.pylibdmtx.decode

✗ from pylibdmtx import decode

encode

✓ import pylibdmtx.pylibdmtx; encode = pylibdmtx.pylibdmtx.encode

✗ from pylibdmtx import encode

from PIL import Image from pylibdmtx.pylibdmtx import decode image = Image.open('datamatrix.png') results = decode(image) for result in results: print(result.data.decode('utf-8'))

Debug

Known issues

breakingOn Windows, libdmtx.dll must be in PATH. Use conda or manually add DLL directory.

fix

Install via conda-forge (includes bundled DLL) or copy libdmtx.dll to a PATH directory.

affects: all

gotchadecode() returns bytes, not str. Must call .decode('utf-8') on data.

fix

Use result.data.decode('utf-8') or appropriate encoding.

affects: all

gotchaInput image must be PIL Image, not file path. Open with Image.open() first.

fix

Always pass a PIL Image object to decode().

affects: all

deprecatedPython 2 support is deprecated; library still installs but may break on Python 2 EOL.

fix

Use Python 3.6+.

affects: <=0.1.10
