SplineWarp
Transformv1coreNeeds full input
Overview
Draw a curve on a feature and the curve where that feature should end up; every pixel between follows. The controls are the same moving-least-squares pins PinWarp uses, sampled along both curves at matching arc length, so a stretched curve still matches its partner.
How to
- Select the node and <kbd>Ctrl</kbd>+click in the viewer to add points (<kbd>Ctrl</kbd>+<kbd>Shift</kbd> starts a new spline).
- Drag the solid dots to warp; drag the rings to re-anchor what moves.
- <kbd>Alt</kbd>+click a destination point to remove that correspondence.

Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| src_splines | Text | String::new( | Not documented yet. |
| dst_splines | Text | String::new( | Not documented yet. |
| samples | Int | 24 | Not documented yet. |
| pin_border | Bool | true | Not documented yet. |
| mix | Float | 1 | Dissolves the effect back toward the input. 0 = off (bit-identical), 1 = full effect. |
Known edges
pin_border pins the input's own frame edge to itself; without it one curve in the middle of frame drags the whole plate after it. Spline sets that do not pair one to one warp nothing and say why.
