| LUTs caching | ||
| ------------ | ||
|
|
||
| The OMERO server ships with a set of look-up tables (LUTs) for rendering images. Users can also | ||
| add their own LUTs to the server. The LUTs available on the server can be retrieved from the | ||
| `/webgateway/luts/` endpoint as JSON data. | ||
|
There was a problem hiding this comment. Although it certainly does not hurt to have this documentation here, it feels a bit at odds with the rest of the README. Should https://omero.readthedocs.io/en/stable/developers/Web/WebGateway.html be extended to cover the LUT endpoints of the OMERO.web gateway? |
||
|
|
||
| To include the `rgb` values of each LUT in the JSON response, append `?rgb=true` to the URL. | ||
|
|
||
| A copy of the JSON output from `/webgateway/luts/?rgb=true` is included in the `omero-web` package | ||
| as a static file at | ||
| https://github.com/ome/omero-web/blob/master/omeroweb/webgateway/static/webgateway/json/luts.json. | ||
|
|
||
| This is used to generate a LUT preview png at `/webgateway/luts_png/` that can be used by clients | ||
| such as OMERO.ivewer and OMERO.figure to display the LUTs in a user-friendly way. | ||
| By using the static `luts.json`, the `/luts_png/` can be quickly generated without needing to load LUTs from | ||
| the server. | ||
|
|
||
| The sequence of LUTs in `/webgateway/luts_png/` correspond to the dynamic list from `/webgateway/luts/`. | ||
| If there are new LUTs on the server that are not found in the static `luts.json`, the `/luts_png/` will | ||
| show a blank placeholder for that LUT. | ||
| To fix this issue following addition of LUTs to the server, the JSON from `/webgateway/luts/?rgb=true` | ||
| should be updated in the `luts.json` file in the `omero-web` package. | ||
