I want to sort images by aspect ratio, and I got some codes like this:
identify * | gawk '{split($3,sizes,"x"); print $1,sizes[1]/sizes[2]}' | sed 's/\[.\]//' | sort -gk 2
This is a output:
28.webp 0.698404
1.webp 0.699544
27.webp 0.706956
10.webp 0.707061
25.webp 0.707061
9.webp 0.707061
2.webp 0.707241
22.webp 1.41431
23.webp 1.41431
24.webp 1.41431
It works, and the first queue is exactly what I want, anyway, but identify is too slower than exiftool especially when handling WebP format, and exiftool have a -r option, so I want to use exiftool to get this output instead, but I don't know how to deal with the output of exiftool -r -s -ImageSize, anyone could help me?
You can find an Aspect Ratio config file in this post (https://exiftool.org/forum/index.php?topic=7275.0) but it returns a ratio, e.g. 16:9, 4:3, 1:1, etc.
You can use this command to get a decimal number, but the api call would also affect other tags.
exiftool -config Exiftool_Aspect_Ratio.config -api "Filter=m/(\d+):(\d+)/;$_=$1/$2" -AspectRatio file.jpg
Example output:
C:\>exiftool -config Exiftool_Aspect_Ratio.config -s -api "Filter=m/(\d+):(\d+)/;$_=$1/$2" -AspectRatio -AspectRatio# y:/!temp/Test_All_QT_tags_x.mp4 "y:/!temp/test3 (2).jpg" y:/!temp/Test2.tiff
======== y:/!temp/Test_All_QT_tags_x.mp4
AspectRatio : 1.77777777777778
AspectRatio : 16:9
======== y:/!temp/test3 (2).jpg
AspectRatio : 1.33333333333333
AspectRatio : 4:3
======== y:/!temp/Test2.tiff
AspectRatio : 1
AspectRatio : 1:1
If you need a decimal output without affecting other tags, then I can work on that later today.
Thanks for your replay. But all I need are only a sequence of files name, I don't care what the aspect ratio is.
Try this then. It will output in about the same format as your example image magick command and then you can just pass through to sort
exiftool -p '$filename ${ImageSize;m/(\d+)x(\d+)/;$_=$1/$2}' /path/to/files | sort -gk 2
