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
