czitools.metadata_tools.scaling #

Scaling helpers for CZI files.

Provides CziScaling which extracts physical scaling (X/Y/Z) from CZI metadata and computes downsampled values and simple ratios. The implementation is defensive: missing values fall back to sensible defaults and ratio computations avoid division-by-zero.

Classes:

  • CziScaling

    A class to handle scaling information from CZI image data.

CziScaling dataclass #

CziScaling(
    czisource: Union[str, PathLike[str], Box],
    unit: Optional[str] = "micron",
    zoom: float = 1.0,
    verbose: bool = False,
)

A class to handle scaling information from CZI image data.

Attributes:

  • czisource (Union[str, PathLike[str], Box]) –

    The source of the CZI image data.

  • X (Optional[float]) –

    The scaling value for the X dimension in microns.

  • Y (Optional[float]) –

    The scaling value for the Y dimension in microns.

  • Z (Optional[float]) –

    The scaling value for the Z dimension in microns.

  • X_sf (Optional[float]) –

    The downscaled scaling value for the X dimension in microns.

  • Y_sf (Optional[float]) –

    The downscaled scaling value for the Y dimension in microns.

  • ratio (Optional[Dict[str, float]]) –

    The scaling ratios for XY, ZX, and ZX_sf.

  • unit (Optional[str]) –

    The unit of measurement for scaling, default is "micron".

  • zoom (float) –

    The zoom factor, default is 1.0.

  • verbose (bool) –

    Flag to enable verbose logging.
