[SOLVED] selecting pictures by size

nyloc · 08-31-2014, 01:39 AM

Does any one know of software that will let me either select all landscape orientated pics or by the pixel size e.g. any pic bigger than 1200x800

You can use the find command with the -size option to find all files a certain size or larger. So if you know how large a file is with 1200x800 pixels then you can use find to find all files that large or larger. See:

man find

If you have imagemagik, you can use identify command like

Code:

cd /dir/of/png
for image in *.png; do
  read w h <<<$(identify -format "%w %h" "$image")
  if (( $w > 1200 && $h > 800)); then
    echo $image
  fi
done

Slow but it works

"find" will only find file size, not image dimensions.
imagemagick is the way to go.
or, there certainly is some image viewer able to do something like that. check out geeqie and gthumb. esp. gthumb has plugins.

...and if your problem is solved, please mark your thread [solved].

Thanks everyone. Using GIMP had taught me that size in bytes is not necessarily related to size in pixels. Identify works a treat and worst case scenario I can set it running before going to bed. Just had a massive learning experience with writing bash scripts to let me tidy up the file name while selecting by size in pixels.

sounds like you're on the path to unix nirvana...

glad it worked out. always satisfying.

As someone who worked on mainframes last century I believe in O'Toole's law rather than unix nirvana.
