Using IM 7.0.7-30 Q16 x64 HDRI from Windows 10 command line, this command...
... produces this error message and no image...
Code: Select all
magick: no images for write '-write' 'test1.png' at CLI arg 2 @ error/operation.c/CLINoImageOperator/4792.
This command...
Code: Select all
magick -pointsize 50 -background pink label:"ABC %[fx:1] 123" test2.png
... produces this image...
It seems to just stop creating the label when it hits the FX expression.
As described
at THIS link, I've always understood FX expressions are supposed to be parsed when creating a "label:".

fx expression work with -label. -label is not the same as label:. I am not sure label: allows direct fx expression evaluation. The developers will need to provide a definitive answer.

GeeMack's examples work fine for me with IM v7.0.7-28 on Windows 8.1. The %[fx:] expression can be more than a simple number:
Code: Select all
magick -pointsize 50 -background pink label:"ABC%[fx:1/7]DEF" fxlabel.png
EDIT to add: it also works on v6.9.5-3 and v6.9.9.40.

This fails for me on IM 7.0.7.29 Q16 Mac OSX
Code: Select all
magick -size 100x -background white label:"%[fx:1]" test1.png
magick: no images for write '-write' 'test1.png' at CLI arg 6 @ error/operation.c/CLINoImageOperator/4792.
Snibgo's command
Code: Select all
magick -pointsize 50 -background pink label:"ABC%[fx:1/7]DEF" fxlabel.png
just shows the image, ABC
