Keep campaign images in the right frame
A channel post with an image URL and target ratio can kick off a consistent Imgix crop request.
Trigger
New Channel Post
Triggered when a new post is published to a channel where your bot is an administrator.
Action
Force Aspect Ratio
Tool to force a target aspect ratio on an Imgix image. Use when a specific W:H frame is needed after choosing fit=crop or fit=fill. Example: 'ar=16:9&fit=crop&w=800' yields a 16:9, 800px-wide URL.
Why this helps
Campaign images arrive in different shapes, leaving someone to fix framing by hand.
- Makes campaign framing instructions reusable.
- Reduces last-minute crop corrections.
- Starts from a published channel brief.

Questions about this workflow
