Using ImageMagick and 4NT to find jpegs by quality level
Using ImageMagick and 4NT to find and modify all jpegs in the current dir who have quality level 94:
for %f in (*.jpg) do (echo %f
& identify -verbose %f | grep Quality
| grep -o “[0-9]*”)
iff “%@execstr[identify -verbose %f
| grep Quality | grep -o “[0-9][0-9]”]” == “94″
then & echo %f & endiff
for %f in (*.jpg) do
(iff “%@execstr[identify -verbose %f
| grep Quality | grep -o “[0-9][0-9]”]” == “94″
then & echo %f &
mogrify -strip -quality 84 %f & endiff)

This is one of several posts that I will be making in the near future, which come directly from my ever-growing toblog.txt file… No code cleanup or lengthly explanations, just commands I’ve run at some point that I thought were worth saving.
