Can I resize multiple images in a directory to 160x160 at once?

Question

I want to resize multiple images that are stored in multiple sub folders in a directory. And I want to replace those images with resized ones by deleting the original ones

Why?

I’ve folder icons for a lot of content in a separate partition. Some of these images are around a megabyte and are 500x500 which is in my opinion overkill for folder icons on 1080p display and I think it’s also reducing performance of nautilus and taking up some valuable space

How is the folder structure?

├── [4.0K]  Zombieland (2009) H
│   ├── [664K]  .folder.png
│   └── [606M]  Zombieland (2009) H.mkv
└── [4.0K]  Zootopia (2016)
    ├── [203K]  .folder.png
    ├── [2.7G]  Zootopia (2016).mkv
    └── [119K]  Zootopia (2016).srt

I want those .folder.png ‘s resized to 160x160. Answer should work on Deep directories.

Other data

Images are generally .png but also .icns, .ico
Images can be stored in really deep directories
all the images have 1:1 aspect ratio
all the images are named .folder.extension
There is an answer here but I think it only works on one image

I'll be glad to provide more information

There are multiple answers there, including at least one that works on multiple images. — muru, May 14 '17 at 12:24

I found an easy solution, run these following commands

sudo apt-get install nautilus-image-converter
nautilus -q

Now go to the directory using Nautilus
Make sure Show hidden files is enabled
Make a search for .folder
Select all the files you want to
Right click and select Resize Images
Select image size as custom size option and fill width = 160 and Height = 160
And file name as Resize in Place
Press Enter

Your images should be resized to 160

Strangely it didn't work on .icns

Not command line, but this python script should do the job for you :)

run it in the root directory you want to affect.

import PIL,os,glob

DIMENSIONS = (160,160)
FILETYPES = ['*.ico','*.icns','*.png']


def get_pictures_from_directory(subject_path,filetypes):
    lst = []
    for extension in filetypes:
        lst.extend(glob.glob(subject_path+"/"+extension))
    return (lst)

def get_folders_in_curr_directory(directory):
    return ([d for d in os.listdir(directory) if os.path.isdir(os.path.join(directory, d))])


def load_and_resize_image(img_path,size_tuple):
    img = PIL.Image.open(img_path)
    img = img.resize(size_tuple)
    return (img)

def save_image(img,img_path):
    img.save(img_path)


def resize_pictures(pictures,DIMENSIONS):
    for picture in pictures:
        img = load_and_resize_image(picture,DIMENSIONS)
        save_image(img,picture)

def run_recursive_resize(base_path,DIMENSIONS,FILETYPES):
    directories = get_folders_in_curr_directory(base_path)
    pictures = get_pictures_from_directory(base_path,FILETYPES)
    resize_pictures(pictures,DIMENSIONS)
    for directory in directories:
         next_path = base_path +'/'+ directory
         run_recursive_resize(next_path,DIMENSIONS,FILETYPES)

run_recursive_resize('.',DIMENSIONS,FILETYPES)

Can I resize multiple images in a directory to 160x160 at once?
