The Bulge/Pinch effect creates a circular distortion that either bulges outward or pinches inward, similar to a magnifying glass or a concave lens effect.
How it works
Bulge/Pinch works by displacing pixels within a circular area. When the strength is positive, pixels are pushed outward from the center (bulge). When the strength is negative, pixels are pulled inward toward the center (pinch).
The effect is strongest at the center of the defined area and gradually diminishes toward the edge of the radius, creating a smooth distortion.
Use cases
- Creating lens distortion effects
- Highlighting specific areas of an image
