#!python3
'''
This is a demo of how you can use the CoreML framework (via objc_util) to classify images in Pythonista. It downloads the trained 'MobileNet' CoreML model from the Internet, and uses it to classify images that are either taken with the camera, or picked from the photo library.

'''
This module provides a Python wrapper around CIImage and CIFilter for using CoreImage filters from Pythonista more easily.
How to use:
1) Create a CImage object. The constructor accepts either a file path, a ui.Image, PIL.Image.Image, or photos.Asset object. Example:
>>> # From a photo:
>>> img = CImage(photos.pick_asset())
>>> # From a ui.Image:
View Geotag Photos.py
#!python3
'''
This is a proof-of-concept script for tagging photos with location data on iOS.
* First, it shows all photos that have no location data *and* are editable.
* Then, a grid of photos in temporal proximity is shown. You can pick multiple photos here.
* When you tap Done, the photo you selected first will get tagged with the average location of the photos you picked in the second step.

# Share sheet extension script for adding new pages to Swift Playgrounds (experimental)
# HOW TO USE:
# 1. Add this script as a shortcut to the Pythonista extension (either from Pythonista's settings or the share sheet extension itself)
# 2. Tap the "Share" button in the Playground app's library.
# 3. Select the playground that you want to add a page to
# 4. Select "Run Pythonista Script" in the share sheet
# 5. Run this script, to select the chapter and page title.
