[grlee77]

Implemented a couple of remaining deprecations missing from the TODO as found by grep -rI "0.19" in the codebase.

Also fixed f2878e5 by adding the removal of draw.circle (forgot to save and commit that change previously!)

[mkcor]

I didn't follow when or why this change was decided on... pandas speaks 'inplace' so it seems more standard to me. Oh well.

[grlee77]

I don't remember, but I think it was for consistency with several other functions that use in_place. It looks like a number of functions under future/graph already have in_place, also morphology.remove_small_holes and morphology.remove_small_objects

[grlee77]

That said, most of those are still in future, so changes are probably expected there. I wonder if there are other prominent examples of inplace aside from pandas?

I don't think SciPy or NumPy tend to use either, usually requiring an out or output argument to be specified instead.

Ok.

also morphology.remove_small_holes and morphology.remove_small_objects

Right, but it looks like the argument is going away altogether for 1.0!

scikit-image/skimage/morphology/misc.py

Line 51 in 7b0d37d

@remove_arg("in_place", changed_version="1.0",

And going NumPy-style instead:

scikit-image/skimage/morphology/misc.py

Line 52 in 7b0d37d

help_msg="Please use out argument instead.")
