Alternative Python image libraries in Google App Engine?

Question

I am thinking about uploading images to the Google App Engine, but I need to brighten parts of the image. I'm not sure if the App Engine API will be enough. I believe that try blending with a white image and partial opacity.

However, if this does not produce the desired results, will there be another Python image library that works with the App Engine? Basically, it was supposed to be pure Python (no related C code or anything else).

Answer 1

PNGcanvas can help if PNG input and output are satisfactory - it does not directly offer the “bright” functionality required, but it allows you to load and save PNG files into memory and access them directly from Python, and this is the only simple Python source file.
