Look-up Tables

WARNING

ome-zarr.js is not yet stable and the API may change in patch releases.

Over 40 LUTs are included in ome-zarr.js. Each lut.png is a png of 256 x 1 pixels. Below these are displayed with a height of 15px:

omezarr.getLuts().forEach((lut) => {
  let html = `<legend>${lut.name}</legend> <img src="${lut.png}" />`;
  document.getElementById("luts").innerHTML += html;
});

To renderImage() with a LUT, we can set the lut attribute of omero.channels:

omero.channels[0].lut = "fire.lut";
let src = await omezarr.renderImage(arr, multiscale.axes, omero);

Click on a LUT below to re-render the image:
