Is it possible to output file type and progressiveness only?

Hi I tried this command to output only file type.
Code: Select all
identify -format "%m" 0000048884_20080529155208.jpg
However, I can't find any info related to a way to find progressiveness. Is there special format letter to return it that I might have missed?
Thanks in advance.

Best I can figure out, you have to extract it from the verbose info:
convert rose: -interlace line rose.jpg
identify -verbose rose.jpg | grep "Interlace:"
returns:
Interlace: JPEG
see

for JPEG progressive via interlace line or plane

I think that should work. How would I have not thought about that???
Thanks so much!
