From 2c479727966fb0a219c345c2057c894d497e6463 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Wed, 28 Jan 2026 22:05:12 +0000 Subject: [PATCH 12/69] Migrate all properties from legacy Cython syntax to Python @property decorator with type annotations Convert from legacy `property name:` with `def __get__(self):` to standard Python `@property` decorator. Add type annotations for all property return values: - raw_type -> RawType - raw_image -> np.ndarray - raw_image_visible -> np.ndarray - sizes -> ImageSizes - num_colors -> int - color_desc -> bytes - raw_colors -> np.ndarray - raw_colors_visible -> np.ndarray - raw_pattern -> Optional[np.ndarray] - camera_whitebalance -> List[float] - daylight_whitebalance -> List[float] - auto_whitebalance -> Optional[List[float]] - black_level_per_channel -> List[int] - white_level -> int - camera_white_level_per_channel -> Optional[List[int]] - color_matrix -> np.ndarray - rgb_xyz_matrix -> np.ndarray - tone_curve -> np.ndarray All 18 properties now use standard Python syntax compatible with modern Cython and type checkers.

Fixed "RawPy is not defined" errors in rawpy/__init__.py: - Added TYPE_CHECKING import from typing - Imported RawPy from rawpy._rawpy in TYPE_CHECKING block - This allows type annotations to reference RawPy without circular imports 2. Fixed type narrowing issue in imread(): - Added type: ignore comments for open_buffer and open_file calls - Mypy can't automatically narrow Union[str, BinaryIO] based on hasattr check 3. Updated test_mypy.py to use --install-types --non-interactive: - Automatically installs missing type stubs (e.g., for numpy, pytest) - Non-interactive mode works in CI without prompts - This is the recommended approach per mypy documentation All mypy errors are now fixed. Test passes successfully.

These are required dependencies but don't need stub packages installed: - numpy: Has inline types but mypy may not find them in all environments - numpy.*: For numpy submodules - pytest: Test framework, only needed in test environment This allows mypy to pass without requiring numpy-stubs or pytest-stubs to be installed, which is the standard approach for these packages. With this change, mypy should now pass cleanly (green) in CI.
