##Resize Images by Custom Height/Width
This custom action resizes images by a custom height. The resized images are moved to a subfolder and the originals remain in the working folder. If resizing by width is desired then remove the x from the following part of the command: x$CUSTOM_COMMAND and change the text Enter Height to Enter Width. This custom action requires YAD and ImageMagick be installed.
- Name: Resize by Custom Height
- Description: Resizes image(s) by custom height
- Command:
CUSTOM_COMMAND=$(yad --entry --title "Custom Command" --text "Enter Height:") ;
mkdir %d/dir && cd %d; for file in %N; do convert "$file" -resize
x$CUSTOM_COMMAND "dir/${file}"; done
Under Appears if selection contains make sure Image Files is checked.
##Resize Images by Maximum Height/Width
This custom action resizes images by a maximum height. So in a folder of 10 images, if only one image has a height over 600 height only that image will be resized. NOTE: The resized image(s) will replace the original image(s), so make a copy of the original(s) before converting. To change to maximum height replace both instances of 600 in the below command. If resizing by maximum width is desired then remove the x from the following part of the command: x600. ImageMagick must be installed for this custom action.
- Name: Resize Images by Maximum Height/Width
- Command:
identify -format '%w %h %f\n' *.jpg | awk '$2 > 600 {sub(/^[^ ]* [^ ]* /, ""); print}' | tr '\n' '\0' | xargs -0 mogrify -resize 'x600>' %N
