Hi everyone,

A new plugin is available. This [Pixels Masker plugin](https://orthanc.uclouvain.be/book/plugins/pixels-masker.html) extends the `/modify` and `/anonymize` REST API routes enabling masking of pixels in the image e.g., to hide Patient information burned in the image.

Note that this plugin is not smart at all and is **not** detecting the areas to mask. It is just a convenience tool to help you anonymize DICOM data completely inside Orthanc provided that you already know where the sensitive information is.

This plugin is available

- as part of the [Windows Installers 25.12.2](https://www.orthanc-server.com/download-windows.php)
- as part of the [orthancteam/orthanc:25.12.2 Docker images](https://hub.docker.com/r/orthancteam/orthanc)
- as [individual downloads](https://orthanc.uclouvain.be/downloads/index.html) (Linux LSB/Windows/MacOS)

Enjoy !

Alain
