.. py:module:: loki2.inference.wsi_meta

.. autoapi-nested-parse::

   Helper functions to load WSI metadata for Loki2.

   This module provides utilities for extracting and processing metadata
   from whole slide images, including MPP (microns per pixel) and magnification.

.. py:function:: load_wsi_meta(wsi_path: pathlib.Path, wsi_properties: Optional[Dict[str, Any]], resolution: float, logger: logging.Logger) -> Tuple[Dict[str, float], float]

   Load WSI metadata and compute target MPP.

   :param wsi_path: Path to the WSI file.
   :param wsi_properties: WSI properties dictionary. Optional keys:
                          "slide_mpp", "magnification".
   :param resolution: Target resolution of the network (MPP).
   :param logger: Logger instance for logging messages.

   :returns:     - WSI properties dictionary with 'mpp' and 'magnification'
                 - Target MPP for processing
   :rtype: Tuple[Dict[str, float], float]

   :raises NotImplementedError: If MPP or magnification cannot be determined.
   :raises RuntimeError: If WSI MPP is invalid or incompatible with network resolution.
