Set Device Pixel Ratio
Tool to set device pixel ratio for an Imgix image. Use when rendering at specific display densities to ensure correct sharpness. Example: 'dpr=2&w=500&h=300' doubles resolution relative to dimensions.
Why this helps
Soft images in interface previews create extra review rounds and visual distraction.
- Makes density requirements explicit.
- Supports sharper renders at known display sizes.
- Cuts avoidable image review corrections.
Setup
Build it in a few focused steps.
- 1Connect Telegram and Imgix to Notis once.
- 2Create an automation that applies the requested device pixel ratio to image URLs.
- 3Choose New Message Received and select a channel for run reports.
- 4Test with an image URL, display dimensions, and a density such as 2.
Questions about this workflow
How should I specify density?
