Code: Select all

convert rose: rose: -set options:compose:args 50,50 -compose blend -composite rose_blend6.png

IM 7.0.5.5 Q16

Code: Select all

magick rose: rose: -set options:compose:args 50,50 -compose blend -composite rose_blend7.png

Try:

Code: Select all

magick rose: rose: -set option:compose:args 50,50 -compose blend -composite rose_blend7.png

DOH! Sorry for the false alarm. Something did look odd, but I could not put my finger on it.

Should not bad syntax raise a warning or error message as per this typo?

The syntax is fine. "-set {key} {value}" will accept anything as {key}. It would take more intelligence than IM has to realise that your {key} is very close to, but not exactly, one of the standard attributes.
