Credit for this goes to SteffenR for porting this action from drupal 6 and imagecache_effects. All I did was clean some things up and put it in this sandbox.

What it does

Creates a "reflection-like" image effect.

How

This module leverages the power of the drupal image module to create a new "reflection-like" effect that can be added to any image style.

It's reusable

The effect can be applied to any image via the image style UI.

User configurable options

• Reflection size
• Alpha transparency
• Reflection location (left, right, top, bottom)
• Reflection background color

Drupal 8 initial port is done.

Everything is functional. Awaiting finalization of the core image API. Testers welcome.
