Using IM 6.9.9-20 Q16 x64 HDRI with Windows 10, I get an unexpected result when running this command...
The command should create three canvases, annotate them with numbers 1, 2, and 3, then crop each canvas into halves. The actual output is these six panels (which I've appended for display)...



Annotate is numbering the panels 1, 3, and 5 as if it's counting relative to the six images in the stack after the crop, even though the annotate operation occurs before the crop and should only affect the original three images.

If I run the same command with IM 7.0.7-8 by substituting "magick" for "convert", the output is as expected with the panels numbered 1, 2, and 3.

I do not think annotate permits fx expressions in IM 6 for the text. However, it does allow escapes such as %w, but not %{fx:w]

I haven't found any descriptions of how "-annotate" handles FX expressions in IM6, but I have tested many variations, and pretty much everything I try seems to work as expected. Even back to version 6.7.7 on bash this would print "Test: 1256.64 200 72"...
The documentation just below THIS link suggests FX expressions should work for at least "label:" and "caption:" since v6.3.2. I suppose the fact that it works for most expressions using "-annotate ..." and IM6 may be unintended.

I stand corrected. If you have found that it works with fx expressions, then the issue is which "letters" it is coded for. Perhaps %[fx:t] is not coded whereas %[fx:w] does work. In that past, I had to ask that other letters be included in certain places, but I do not recall which letters or in which functions.
