magick x.png x.jpg Fails:
That is odd, since you do have both PNG and JPG installed in your delegates.

Re: IM 7.0.8-13 reports incorrect "-version" number

I can confirm the same on my Mac OSX for IM 7.0.8.13 -- it reports 7.0.8.12.

But the legacy version 6.9.10.13 reports correctly.

Re: Confused about median

The virtual pixel setting is used to extend the image at the borders, so that the edge pixels have values next to them so that each edge pixel can be in the center of a neighborhood. See, for example, https://www.cs.auckland.ac.nz/courses/compsci373s1c/PatricesLectures/Image%20Filtering_2up.pdf for ...

Re: Confused about median

It replaces only the center pixel in each 3x3 neighborhood with its median. So when the command finishes, every pixel will have been replace by the median in its 3x3 region surrounding that pixel. This is the way most regional statistics operators work. For the mean, each pixel will be replaced by t...

Re: Converting Photoshop PDF with Transparency

I played with your file in Photoshop CC 2018. If I save it again and turn off "Preserve Photoshop Editing Capabilities" in the PDF Save dialog box, then it seems to work fine when I convert to PNG using Ghostscript 9.24.

Re: Confused about median

With even dimensions, I do not thing there will be any averaging done for the middle two. IM probably takes either the first or the second of the two middle values. Looks like from your tests, it takes the second. Try with odd number of values and see what happens. Only the middle value is replaced ...

Re: convert unable to read font

If you don't specify a font what one is used by default? I think it relies on the system default font, but am not 100% sure of that. In the font family documentation https://imagemagick.org/script/command-line-options.php#family it seems to say it is Arial. But that only works if you have arial on ...

Re: Unwanted gaps between combined PNG images

It has been this way since IM 6 first started. But IM 6 is forgiving. IM 7 is not. See https://imagemagick.org/Usage/basics/#why

Re: Unwanted gaps between combined PNG images

By the way, the order of the options in the code does not seem to matter in my case.
It would in ImageMagick 7.
