VoxelImage.chunk_slice_indices(chunk_id, return_indices=False)[source]#

Calculate the slice indices for a given Zarr chunk.

This method computes the first and last+1 indices for a specific Zarr chunk within the array, based on the block’s ID. Useful for working with chunked data in parallel processing.

Parameters:: chunk_id (int) – The ID of the block for which to calculate the slice indices.
Returns:: If return_indices is True, a tuple containing six integers: (box, bex, boy, bey, boz, bez). These represent the start and end indices for the block in the x, y, and z directions, respectively. If return_indices is False, a tuple containing the three slices: (slice(box, bex), slice(boy, bey), slice(boz, bez)).
Return type:: tuple
