Migrating Python 2 to 3: images

[Joshua Smith]

I need to read and resize an image in my google app engine app. In my python2.7 code, this is simply:

from google.appengine.api import images

image = images.resize(image, width=1024, output_encoding=images.JPEG, correct_orientation=images.CORRECT_ORIENTATION)

I can’t find anything the migration guide that suggests an alternative to this API (but several places say I need to find one). So helpful.

What does this august body recommend I use to replace the above two lines of code? I certainly don’t want to have to use some web-based micro-service for such a simple thing.

The migration guide does have a brief section in the overview: https://cloud.google.com/appengine/docs/standard/python/migrate-to-python3/migrating-services which suggests migrating to third-party image services. However, depending on your use case (keeping in mind impacts on security and performance) you may find it more suitable to install a library which performs the operation in-place on your App Engine instance. Pillow is one I have used in the past.
