Feature request: Intensity values & auto brightness #123

Open StephanPreibisch opened 3 years ago

StephanPreibisch commented 3 years ago

Hi, we should think about adding the very basic features (that are more complex in this context) of displaying a pixels intensity and auto brightness adjustment to BDV. Happy to discuss and contribute!

I also miss the values displayed when pointing to (x,y,z) pixels... Also a colorbar scale(s) would be nice.

This reminded me of this issue , because the user will have to navigate larger value ranges when supporting more data types.

Auto-contrast UI

What about adding an option for auto-contrast somewhere here? Maybe add set range auto?

Pixel values UI

Two suggestions:

  1. Add value next to name, current, active, color
  2. Make a new card, called Sources pixel values, where you repeat all the source names

Maybe the second approach could have the advantage that if one hides this card, the code would know that it does not have to fetch the pixel values (in case that is expensive).

Maybe to clarify my terminology:

range: the current min max values of the Converter bounds: the min and max limits of the UI sliders

For datatypes like uint64 it is, in my view, not trivial to set the bounds such that the user can still sensibly use them. In MoBIE we have thus implemented some logic that computes the bounds given the current range, happy to discuss this.
