Batch resize images into new folder using ImageMagick

Question

I have a folder of images over 4MB - let\'s call this folder dsc_big/. I\'d like to use convert -define jpeg:extent=2MB to convert them to

Answer 1

I found that cd-ing into the desired folder, and then using the bash global variable $PWD made my convert not throw any errors. I'm utilizing ImageMagick's recently implemented caption: http://www.imagemagick.org/Usage/text/#caption function to label my images with the base filename and place them in another directory within the first.

cd ~/person/photos
mkdir labeled
for f in $PWD/*.JPG; do
    width=$(identify -format %w $f)
    filename=$(basename $f .JPG)
convert -background '#0008' -colorspace transparent -fill white -gravity center -size ${width}x100  caption:"${filename}" ${f} +swap -gravity south -composite "$PWD/labeled/${filename}.jpg";
done
