Convert Images on Linux
To Thumbs
Alt dette piping sletter EXIF data
for i in *.JPG; do djpeg $i | pnmscale -width 800 | cjpeg -opti -progr -qual 90 > TN_$i; echo $i processed; done
Brug convert istedet den bevarer EXIF
for i in *.JPG; do convert -resize 800 -quality 90 $i TN_$i; echo $i processed; done
Time comparision(on the Raspberry PI):
# time djpeg DSCN1111.JPG | pnmscale -width 800 | cjpeg -opti -progr -qual 90 > TN_DSCN1111.JPG
real 0m37.604s
user 0m25.870s
sys 0m1.750s
# time convert -resize 800 -quality 90 DSCN1111.JPG TN2_DSCN1111.JPG
real 5m9.545s
user 2m19.830s
sys 0m8.250s
Hvis den skal tælle op kan man bruge denne for løkke.
t=1; w=`ls -l | wc -l`; for i in *.JPG; do let t++ ; echo "Converted $i($t/$w)"; done
