# svg-stroke-trace
|
||||
|
||||
An authored SVG path draws from start to finish using its measured `getTotalLength()`. Paths ending in a close command (`Z`) receive a restrained fill after the stroke completes; open paths (signatures, waves) stay stroke-only. The finished mark then holds until the frame cuts.
|
||||
|
||||
3.5s authored, elastic HOLD, exit `none` by default.
|
||||
|
||||
## Variables
|
||||
|
||||
| id | type | default | notes |
|
||||
| -------------- | ------ | ----------- | ----------------------------------------------------------------------------------------------------------------- |
|
||||
| `path` | string | a wave path | SVG path data in the 1024x520 viewBox. A trailing `Z` is the single owner of fill behavior. |
|
||||
| `stroke_width` | number | `12` | Stroke width in viewBox units (2 to 32). |
|
||||
| `accent` | enum | `green` | Trace and fill color: green rides `--brand`, blue rides `--accent`, violet rides `--accent-2`. |
|
||||
| `exit` | enum | `none` | `none` holds until the cut; `fade` departs opacity-only; `up` is the upward fade (the pre-Wave-J default ending). |
|
||||
|
||||
## Mount
|
||||
|
||||
```html
|
||||
<div
|
||||
class="clip"
|
||||
data-composition-id="svg-stroke-trace"
|
||||
data-composition-src="./svg-stroke-trace.html"
|
||||
data-variable-values='{"path":"M 120 400 L 512 120 L 904 400 Z","stroke_width":10,"accent":"blue"}'
|
||||
data-start="0"
|
||||
data-duration="3.5"
|
||||
data-track-index="0"
|
||||
></div>
|
||||
```
|
||||
|
||||
Elastic root: no `data-width`/`data-height`; it fills whatever box the host clip gives it. Timeline registers under the literal `svg-stroke-trace` key.
|
||||
|
||||
## Notes
|
||||
|
||||
- Dash values come from the real measured path length (never the `pathLength` attribute, never `non-scaling-stroke`), so any authored geometry draws exactly once.
|
||||
- The hold is one finite vertical drift cycle, never a repeating tween.

svg-stroke-trace: HyperFrames video primitive (intros and reveals)
|
||||
|
||||
An authored SVG path draws from start to finish using its measured length.
|
||||
Closed paths receive a restrained fill after the stroke completes. Open
|
||||
paths remain stroke-only, which keeps signatures and waves clean.
|
||||
|
||||
Variables:
|
||||
- path (string): SVG path data for the traced mark.
|
||||
- stroke_width (number, default 12): stroke width in viewBox units.
|
||||
- accent (green | blue | violet, default green): trace and fill color.
|
||||
- exit (none | fade | up, default "none"): optional departure.
|
||||
|
||||
Envelope, fixed IN and OUT with elastic HOLD only:
|
||||
IN_BASE = 1.85s, stroke draw followed by optional closed-path fill
|
||||
HOLD = max(0, D - IN - OUT), one subtle vertical drift cycle
|
||||
OUT_BASE = 0.45s departure when exit is fade or up, 0s when exit is
|
||||
none (the default: the finished mark holds until the cut)
|
||||
If D is shorter than IN_BASE + OUT_BASE, IN and OUT compress together.
|
||||
The timeline is never time-scaled.
|
||||
|
||||
Mount contract: the runtime clones only this template. #root fills the host
|
||||
box, establishes the container query basis, has no data-width or data-height,
|
||||
and registers one paused timeline under the literal svg-stroke-trace key.
