Octave 4.3.90 with (Ubuntu) linux: I have uninstalled and re-installed the image package. What I then get is a lot of "deprecated" messages during installation (compilation of some image package functions), but still no warning message after "pkg load image".

I assume the shadowing itself will be fixed in one of the next releases of the image package. But the missing warning message itself under (my ?) linux is what makes me suspicious.

On Debian GNU/Linux I see the exact same behavior you are describing, so I don't see any system-dependent difference:

Is this a bug or just the way the image package is working for now?

When I use Octave 4.3.90 and do "pkg load image" with the current image-2.6.2 package, then

  • I do NOT get any warning message under Linux. When doing "which rgb2gray" then the answer is that it would use rgb2gray from the image package. When I look in the octave folder "scripts/image" then I do see a second rgb2gray.m file there.
  • I DO get a warning message "rgb2gray.m shadows a core function" under Windows.

This seems odd to me, but I am unsure if this hints to a deeper problem. Shouldn't the same shadowing also happen under Linux? Shouldn't this provoke the same warning message under Linux, then?
