First work items

• Basic structure, 4 quadrants and one left column for controlling everything
• Load one volume
• Display in one or several quadrants
• Display loaded volume
• Display metadata in left column

Then

• Specify cutting plane in each quadrant
• Link the four panes (mono volume)
• Multi volume

Visualization

• Scale bar (eg. |---| 10 um)
• Small "axes reference frame" materialized on the image
• Option to display image in 1:1 zoom mode (1 image pix = 1 screen pix).

For the future:

• If overlay feature is implemented: display both values under cursor (the one on the main image, and the one on the overlaid image). Ludo.
• If 4d data feature is implemented: Is 4th dimension locked to one slider (probably yes if 4th dim is time, but not always the case). If not time, do we want to toggle display on the 4 dimensions? Ludo.
• If casting feature is implemented: use the colormap used for display in the casting rules. Ludo.

Ideas

• If volume loaded is "projections" (NX file): offer the possibility to normalize (flat-field) the projections
• Small filters ? (median)
• "Searchlight" feature from Captain Nemoz ?
