Right-click in the live preview now procs a box that is actually visible and populated with the zoomed region, and each Zoom View Shape sculpts the box per spec. OBS-style derivative: magnifier box shows the composited region and dims the surroundings (same pattern as OBS "zoom" / preview region highlights). Root causes of the invisible box (two WPF traps, recorded in MyMistakes.md): - Empty <VisualBrush Stretch="None"/> used as an OpacityMask paints nothing, so the mask alpha is 0 and the WHOLE box (border included) went transparent. - ZoomBox lived inside CanvasGrid while its VisualBrush sampled CanvasGrid — a circular reference WPF renders as nothing. Hoisted ZoomBox to a sibling of CanvasGrid inside a new PreviewCanvas wrapper (same 1920x1080 space). Shape semantics (MainViewModel.ActivateZoom): - Circle: square, click point = center. - VerticalRectangle (phone): tall 9:16, click point = top-left corner. - HorizontalRectangle (tablet): wide 16:9, click point = top-left corner. - Boxes stay fully inside 1920x1080 via Math.Clamp. UI: ZoomRectOutline/ZoomCircleOutline shapes replace the square Border; circle clips the box to an EllipseGeometry; brush Visual released when inactive. Zoom View Shape dropdown now uses the standard YtComboBox style. Test (Good Dog rule, one integration test): ZoomBoxInteractionTests verifies aspect/anchoring/clamp per shape and the matching outline+clip in the real MainWindow. Full suite 404 passed, 0 warnings. Memory: HANDOFF.md zoom state updated; WPF VisualBrush traps appended to MyMistakes.md.

# HANDOFF — 2026-10-07
|
|
|
|
## Branch
|
|
- main (no feature branch)
|
|
|
|
## Dirty files
|
|
- None (zoom box fix + test committed as a work unit this session).
|
|
|
|
## What just happened
|
|
- Fixed the zoom box: right-click in live preview now procs the selected Zoom View
|
|
Shape with correct anchoring and a visible, populated box (previously invisible —
|
|
empty OpacityMask made the whole box transparent and the VisualBrush pointed at the
|
|
CanvasGrid *ancestor*, a circular reference WPF renders as nothing).
|
|
- Zoom View Shape dropdown now uses the app's standard `YtComboBox` style.
|
|
- One integration test added (Good Dog Rule): `ZoomBoxInteractionTests` — circle is a
|
|
centered square, phone is a tall 9:16 rect and tablet a wide 16:9 rect, both anchored
|
|
top-left at the click, box stays inside 1920x1080 (clamp), and the UI shows the right
|
|
outline/clip per shape. Full suite: 404 passed, 0 warnings.
|
|
|
|
## Zoom feature state
|
|
- Models/ZoomState.cs + Models/ZoomShape.cs (Circle, VerticalRectangle, HorizontalRectangle)
|
|
- ViewModel: zoom box activation/move/dismiss; compositor output crops+scales the zoom region; dimming updates
|
|
- PreviewPane: zoom box is a *sibling* of CanvasGrid inside a new `PreviewCanvas` wrapper
|
|
(so the VisualBrush can sample CanvasGrid without a circular reference); shape-aware
|
|
outline (`ZoomRectOutline`/`ZoomCircleOutline`) + ellipse clip for Circle
|
|
- Shape semantics in `MainViewModel.ActivateZoom`: Circle = click point is center, w=h=min(maxW,maxH);
|
|
VerticalRectangle = 9:16 tall, HorizontalRectangle = 16:9 wide, both anchored top-left at the click; clamped to frame
|
|
- Settings (OverlayHost) Zoom View Shape persisted via LayoutStore
|
|
|
|
## Known issues / follow-ups
|
|
- Background toggle bug mentioned earlier: when clicking "Use default background" in layer properties, nothing happens. Need to investigate - binding exists (UseDefaultBackground), VM has handler that invalidates bake and updates. May need to look up Source background logic.
|
|
|
|
## Next step
|
|
- User runs the app live/test to eyeball the zoom box visuals (border shows, region content visible,
|
|
circle is round, phone/tablet anchored at the click point). Then background "Use default background"
|
|
toggle if still needed. Otherwise stand down.
