Warnings in Spectral Viewer

Using enmapboxplugin.3.10.20220119T091443.develop

As soon as I move the color bars, I get:

I didn’t get those warnings on my Windows system.

Would be helpful, if you could manually edit the code. Replace the bandNo with an int(bandNo):

Does that work?

[Agustin Lobo]

I get:

[Andreas Janz]

So nothing changed, right?
Please try to also cast the sampleSize: int(QgsRasterLayer.SAMPLE_SIZE)

[Agustin Lobo]

Fixed!

resolves #932

Another one. This one might be related to the image displaying not being updated when moving the color bars:

Will close this here. For more warnings, open an issue in GitHub.

[Agustin Lobo]

I can’t remember how to get the 3 bars to define the raster composite from the spectrum…
