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.

loki2.inference.wsi_meta.load_wsi_meta(wsi_path: pathlib.Path, wsi_properties: Dict[str, Any] | None, resolution: float, logger: logging.Logger) → Tuple[Dict[str, float], float]

Load WSI metadata and compute target MPP.

Parameters:

• wsi_path – Path to the WSI file.

• wsi_properties – WSI properties dictionary. Optional keys: “slide_mpp”, “magnification”.

• resolution – Target resolution of the network (MPP).

• logger – Logger instance for logging messages.

Returns:

• WSI properties dictionary with ‘mpp’ and ‘magnification’

• Target MPP for processing

Return type:

Tuple[Dict[str, float], float]

Raises:

• NotImplementedError – If MPP or magnification cannot be determined.

• RuntimeError – If WSI MPP is invalid or incompatible with network resolution.
