OMERO figure creation app

Project description


An OMERO.web app for creating figures from images in OMERO.

For full details see


  • OMERO 5.2.6 or newer.

Installing from Pypi

This section assumes that an OMERO.web is already installed.

Install the app using pip:

$ pip install omero-figure

Add figure custom app to your installed web apps:

$ bin/omero config append omero.web.apps '"omero_figure"'

Display a link to ‘Figure’ at the top of the webclient:

$ bin/omero config append omero.web.ui.top_links '["Figure", "figure_index", {"title": "Open Figure in new tab", "target": "_blank"}]'

Now restart OMERO.web as normal.


OMERO.figure version 2.x requires OMERO.web 5.2.6 or newer. This is due to a Django Framework compatibility and to a required package reorganization in OMERO.figure in version 2.0 so the application can be distributed from Python Package Index PyPi.

Enabling figure export

This section assumes that an OMERO.server is already installed.

Figures can be exported as PDF or TIFF files using a script that runs on the OMERO.server. This script needs to be uploaded to the OMERO.server and its dependencies installed on the OMERO.server machine.

The script can be uploaded using two alternative workflows, both of which require you to be an admin.

Option 1: Connect to the OMERO server and upload script via the CLI. It is important to be in the correct directory when uploading so that the script is uploaded with the full path: omero/figure_scripts/

$ cd omero_figure/scripts
$ path/to/OMERO.server/bin/omero script upload omero/figure_scripts/ --official

Option 2: Alternatively, before starting the OMERO.server, copy the script from the figure install /omero_figure/scripts/omero/figure_scripts/ to the OMERO.server path/to/OMERO.server/lib/scripts/omero/figure_scripts. Then restart the OMERO.server.

Now install the script’s dependencies:

$ pip install reportlab
  • Optional: Figure legends can be formatted using Markdown syntax. To see this correctly in the exported PDF info page, we need Python Markdown installed:

$ pip install markdown


We use Grunt for various tools. See for an introduction.

Install Node from, then:

$ cd omero-figure
$ npm install

Install Grunt CLI as described on

To compile jst templates:

$ grunt jst

To concatenate js files into a single figure.js file that is used in the app:

$ grunt concat

During development, you’ll want to have both of these run whenever the relevant files are edited. This can be achieved with:

$ grunt watch

To update the demo figure app at we have a grunt task that concats and moves js files into demo/. It also replaces Django template tags in index.html and various js code fragments with static app code. This is all handled by the grunt task:

$ grunt demo

This puts everything into the omero-figure/demo/ directory. This can be tested locally via:

$ cd demo/
$ python -m SimpleHTTPServer

Go to http://localhost:8000/ to test it. This will not install the script and dependencies required to export the figure as PDF.

To update the site:

It is also possible to run the demo in docker without installing anything locally:

$ docker build -t figure-demo .
$ docker run -ti --rm -p 8000:8000 figure-demo


OMERO.figure is released under the AGPL.
