Actually ... I spoke to soon. I discovered this:
identify -format "%[fx:a]" my.png
is not behaving as I initially thought. So maybe Ralf or someone else
knows a better fx expression to use?
>identify -verbose file.png | perl -pe 'while(<STDIN>){ if(/^\s.*alpha:
>(\w+)-bit/){print "$1";}}'
>Luke
Thanks for your post Luke! I didn't see your reply until I had already
figured out something similar, but seeing your post helped me see I was
on the right track. I'm doing something in java with the -verbose
output for now, which isn't nearly as terse as perl but it works. Would
still prefer a -format expression if there is one.
