Sort images by resolution
Related articles
When recovery of files done and you restored images with help of a post recovery tasks script then it could be wise to sort images by the resolution. This will help to sort the photos you made, webcam images or any other images into the folders by the resolutions, most of them are often using the same related image resolutions.
Collect info about images
collect-info-about-images.sh
#!/bin/bash
if [ 'XX' != 'XX'"$1" ]; then 
 if [ -f "$1"  ]; then
# mime part start
  IsIt=$(file "$1" --mime-type -b);
  NeedImageOnly="ItIs_"${IsIt/'/'*/}
   if [ "$NeedImageOnly" == "ItIs_image" ] ; then
# mime part end
ImageInfoFEH=($(feh -l "$1"))
IfDamaged=${?}
ImageType=${ImageInfoFEH[9]}
   Height=${ImageInfoFEH[11]}
    Width=${ImageInfoFEH[10]}
   if [ "$IfDamaged" != '0'  ]; then 
    echo "$1" "Damaged" "${IfDamaged}";
   fi;
    echo "$1"'|'W'|'$Width'|'H'|'$Height'|'Format'|'$ImageType'|'Errors'|'$IfDamaged'|' >> collect-info-about-images.txt
# mime part start
  fi
# mime part end
   else
    echo The « "$1" » is not a valid file name.
  fi
 else
  ScriptsName=${0##*/}
   find -type f -exec sh -e "./$ScriptsName" "{}" \;
  #find -type f  -name "*.jpg" -o -name "*.gif" -o -name "*.png" -exec sh -e "./$ScriptsName" "{}" \;
fi
The $IfDamaged variable contains an exit status code returned by feh.
You can also install pngcheckAUR to check integrity of "PNG, JNG or MNG" and/or jpeginfoAUR and use output of errors in the $IfDamaged variable or modify script to skip adding of damaged files into a collect-info-about-images.txt file.
Example of pngcheckAUR check resuslt:
./f939799496.png invalid IDAT row-filter type (11) ./f939799496.png private (invalid?) IDAT row-filter type (236) (warning) ./f939799496.png private (invalid?) IDAT row-filter type (231) (warning) ./f939799496.png invalid IDAT row-filter type (49) ./f939799496.png zlib: inflate error = -3 (data error) ERROR: ./f939799496.png OK: ./f218842888.png (532x552, 32-bit RGB+alpha, non-interlaced, 95.8%).
Example of jpeginfoAUR check result:
f62152912.jpg 5678 x 2829 24bit Exif N 11625509 Corrupt JPEG data: 1074 extraneous bytes before marker 0xd9 [WARNING] f124619744.jpg 144 x 119 24bit JFIF N 5813 [OK]
To extract necessary data from a string in a script is better to use an expression instead of an extern program as sed or gawk to make a script work a little faster, e.g.
AA="$(jpeginfo -c f62152912.jpg)";
ZZ="${AA/*' [OK]'/}"; 
if [ 'XX'"$ZZ" == 'XX' ]; then 
  echo File is good'!!!';
fi
The collect-info-about-images.sh script generates data about images by pattern:
full path to image|Width|size|Height|size|Format|type of image|Errors|exit code by feh|
Example: Images/f269351998.bmp|W|40|H|39|Format|bmp|Errors|0|
Sort images by resolution
This script creates folders based on the resolution. You can set your limitations about how many files should be in each folder and how many sub-directories in a base file type named folder. When limit is reached a new number in the order will be added to a directory name for creation. If you have a really huge amount of files and don't want to overload a single folder with all of them then you can also add your own counters for a new sub-folders after the base destination variable IfExist="${Destination}/, just look out for quotes " to be in the begin and end of a whole destination path. It use to be much more easier to browse folders with a limited amount of images, thumbnails loads much faster and to remember or add to favorite a folder number/name instead of trying to find once more same image in an overloaded folder out of probably thousand images there.
