I began the implementation in that regard and modernised the package 
according to current standards. Everything seems very promising.

However, I came across a different issue with python-imgviz. In newer 
versions, imgviz depends on the package cmap.

Cmap was released in 2023 to provide a minimal library which gives 
access to the colour maps of large ecosystems such as matplotlib.

At the moment cmap only depends on numpy but has heavy dependency groups 
[1].

Cmap itself is released under the BSD-3 license but includes 10 
different licenses. [2]

The documentation clearly states that cmap can provide "[...] all of the 
colormaps in matplotlib, [...] (and more), with no dependencies beyond 
numpy".[3]

My next step is to validate the licenses of cmap and the code to verify 
if potential licensing issues arise.

If no issues arise I will file an ITP, package cmap first, where 
possible exclude all of the dependency groups, and then continue my work 
with python-imgviz.

If there are issues, I will approach the maintainers of imgviz to 
resolve those concerns.


Best,
