JSF UI Deprecation
This requires to have the JSF UI addon installed on your server that is deprecated since Nuxeo Platform LTS 2019.
Please refer to the Web UI documentation.

The diff capabilities of the Nuxeo Platform now include picture comparison thanks to Nuxeo Diff Pictures. This addon displays a dialog where the user can spot the differences between two pictures. The compared pictures can be of different formats (JPEG, PNG, ...) or dimensions, leveraging ImageMagick capabilities in this area. When the two pictures have the same format and the same dimensions, the user can also set-up a "Fuzzy" comparison parameter (to remove noise when comparing JPEGs for example), and to choose the colors used for to highlight the differences.

When you compare two documents or versions of a document, the elements below are compared:

  • The metadata (title, coverage, modification date, etc),
  • The content.

You can compare documents in any space of the Nuxeo Platform: workspaces, sections...
