Hi I tried this command to output only file type. 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
http://www.imagemagick.org/script/comma ... #interlace
for JPEG progressive via interlace line or plane

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