silx-view: Plugin for extra DataView

[vallsv]

Hi,

I would like to propose python plugin for silx viewer to allow to create extra dataviewers.

For instance depending on the data you are browsing we could provide a bit more adapted data views.

This views could be handled by different project, or different beamlines if they really cares.

This would not remove anything to the actual silx viewer. But will provide a bit more flexibility if we need.

• BLISS could provides some extra viewers for scans
  • Flatfield for tomo scans
  • ROI location in detector images
• Pyfai could provide a dedicated view for integrated data (i have juste created https://github.com/silx-kit/pyFAI/issues/1823)

Python already provide the machinery for that (entry points, used by pytest and Lima for example). And a DataView was already designed as a pluggable object.

If I understand well, the idea would be to have external packages providing some silx-view entry-points that defines a DataView and control its priority. This way, it would be included in the viewer as an extra tab but without any side-effects on the other views/state of the viewer. That sounds nice to me.

I'm wondering if it can have some issues with stuff that is shared across viewes like the colormap dialog.
