OME-Zarr

OME-Zarr is the main image format for odon.

What Works Well

  • multiscale image pyramids
  • on-demand tile loading
  • per-channel display controls
  • responsive single-view inspection
  • mosaic workflows across many ROIs

Viewer Assumptions

The current viewer is focused on 2D XY inspection.

In practice, that means:

  • the first multiscales[] entry is used as the main image
  • XY viewing is the primary path
  • other axes such as z or t are currently treated more narrowly than in a full multidimensional viewer

Opening Local OME-Zarr

cargo run -- "/path/to/ROI1.ome.zarr"

You can also open OME-Zarr through a project file or as part of a mosaic.

Rendering Behavior

The viewer uses a tile-based, coarse-to-fine approach:

  • only visible tiles are requested
  • coarse levels appear first
  • finer levels replace them as data arrives

This keeps large pyramids usable during zoom and pan.
