Bash scripting 7 – Image resize

So moving on to resizing images, I have created two scripts. The first extracts the image size from the photo metadata.

echo display metadata image size in photos
echo
echo "requires exiftool as a dependency"
echo "requires gm (graphics magick) as a dependency"


for file in *.JPG # apply to all files ending with JPG
do
    filename="${file%.*}"
    exiftool -TAG -s -ImageSize ${file}
done

The second script resizes each image to the specified new size. Then displays the new metadata to help confirm successful operation.

echo resize photos
echo
echo "requires exiftool as a dependency"
echo "requires gm (graphics magick) as a dependency"

for file in *.JPG # apply to all files ending with JPG
do
    filename="${file%.*}"
    gm mogrify -resize 1024x768 $file  
    exiftool -TAG -s -ImageSize ${file}
done
