PyPhotoCollage

Combines 3 or more images into a collage, maintaining image aspect ratios and distributing images evenly.

Dissatisfied with the Siri Shortcuts image gridding capability, I wanted a photo collage tool that can distribute images evenly. It grew into the current utility.

After looking around, the idea for this tool came from Johannes Treitz's blog post (which no longer exists...). The problem is reduced to the partition problem, for which I used this SO implementation. Main function was modified (significantly) from delimitry's collage_maker.

Notes for Pythonista and Siri Shortcut versions

Photo collage can crash if too much memory is used
If this happens, use the included "Preprocess images" utility to downscale images to a smaller size, then rerun Photo collage
It will also run faster if preprocessing is done first
Can run by sharing images from the Share Sheet (works better with Siri Shortcut; Pythonista version makes you reselect images)

Pythonista version for iPhone/iPad/Apple Silicon Mac

Takes no arguments.
Options are specified by the user when run.
Simply place in the app, locally or though iCloud.
If you want to run it from e.g. iOS Shortcuts, you'll need to store it locally.
If you want to run it from the Share Sheet, you'll need to add it to the Pythonista extension (see image below)
- Due to limitations in Pythonista, starting Photo collage from the share sheet will not pass through the selected images; you'll need to reselect them
- It crashes when more than a handful of images are passed via the share sheet, so I had to revert that functionality

Native Siri Shortcut

PyPhotoCollage is also implemented as a vanilla Siri Shortcut that runs on Mac/iPhone/iPad
Has all the same options and capabilities
It's slow compared to the Python version; very slow

Mac/PC CLI version

Requirements

Python3
PIL (Pillow)

Photo collage maker

positional arguments:
  files

options:
  -h, --help            show this help message and exit
  -f FOLDER, --folder FOLDER
                        folder with 3 or more images (*.jpg, *.jpeg, *.png)
  -R, --recurse-input-folder
                        recurse into subfolders of input folder
  -F FILE, --file FILE  file with newline separated list of 3 or more files
  -o OUTPUT, --output OUTPUT
                        output collage image filename
  -t COLLAGE_TYPE, --collage-type COLLAGE_TYPE
                        collage type (default: nested; possible: nested, row, column)
  -O ORDER, --order ORDER
                        order of images (default: input_order; possible: filename, random, oldest_first, newest_first, input)
  -S MAX_SIZE, --max_collage_size MAX_SIZE
                        cap the longest edge (width or height) of resulting collage
  -r TARGET_ASPECT_RATIO, --target-aspect-ratio TARGET_ASPECT_RATIO
                        target aspect ratio for collage
  -g IMAGEGAP, --gap-between-images IMAGEGAP
                        number of pixels of transparent space (if saving as png file; otherwise black or specified background color) to add between neighboring images
  -m ROUND_IMAGE_CORNERS_PERC, --round-image-corners-perc ROUND_IMAGE_CORNERS_PERC
                        percentage of shortest image edge to use as radius for rounding image corners (0.0 to 100.0)
  -M ROUND_COLLAGE_CORNERS_PERC, --round-collage-corners-perc ROUND_COLLAGE_CORNERS_PERC
                        percentage of shortest collage edge to use as radius for rounding collage corners (0.0 to 100.0)
  -b BACKGROUND, --background-color BACKGROUND
                        color (r,g,b) to use for background if spacing is added between images
  -c COUNT, --count COUNT
                        count of images to use, if fewer are desired than those specified or contained in the specified folder
  -a, --no-no_antialias-when-resizing
                        for performance, disable antialiasing on intermediate resizing of images (runs faster but output image looks worse; final resize is always antialiased)
  -i INIT_SIZE, --init-image-size INIT_SIZE
                        to derease necessary memory, resize images on input to set longest edge length
  -N MAX_RECURSION_DEPTH, --max-nested-collage-depth MAX_RECURSION_DEPTH
                        maximum number of levels of nesting. The more levels there are, the larger the size difference will be between the smallest and largest images in the
                        resulting collage (default: 2)
  -s, --show-recursion-depth
                        show recursion depth by adding border to images
