@galavi/ome-zarr-adapter

OME-Zarr adapter for Galavi.

Opens an OME-Zarr store via zarrita, reads multiscales metadata, and exposes a Galavi-compatible tile fetcher that converts zarr chunks to r16float tiles.

Supports OME-Zarr v0.5 (Zarr v3) and v0.4 (Zarr v2). Handles non-spatial selection dimensions (c, t, ...).

Install

npm install @galavi/ome-zarr-adapter zarrita

The adapter has no runtime dependency on galavi itself; it produces plain ArrayBuffer tiles (r16float packed) plus metadata that you wire into Galavi sources on your side.

Usage

import { openOMEZarr, getVolumeTransform, getPhysicalSpace } from "@galavi/ome-zarr-adapter";

const info = await openOMEZarr("https://example.com/sample.ome.zarr");
const { scale, translate } = getVolumeTransform(info);
const space = getPhysicalSpace(info);

const tile = await info.fetchTile({
  level: 0,
  position: [0, 0, 0],
  selection: { c: 0 },
});
