Length dim already mask tip-to-tip (locked by test). Width labels move axis-left off the wood via labelAt; font steps down to max(22, scale*1.0). Inventory/overlay crop FILL 0.8→0.9; CAPTURE/PHOTOS docs match.

# Milestone 2 — Photos
|
||
|
||
Builds on Milestone 1. Spec for calibration math and inventory PNG properties: `docs/CAPTURE.md`.
|
||
This milestone gets every photo of one slab background-removed and cropped store-ready.
|
||
It does not fill Complete-listing taxonomy, SKU, price, or copy. It does not create a WooCommerce product.
|
||
No inference URL. No model. Mask and crop for non-calibration shots reuse the approved calibration params as ordinary client code.
|
||
|
||
## Goal
|
||
|
||
Phone capture of one slab → a lined-up set of Woo-compatible inventory PNGs, plus Milestone 1 calibration numbers on the reference shot, plus one annotated copy of the calibration PNG with dimension overlays.
|
||
|
||
## Use case
|
||
|
||
1. User adds a batch of one or more photos of the same slab (Setup rules from Milestone 1: green or black sheet, top-down reference expectations still apply to the calibration choice).
|
||
2. User selects which photo in the batch is the calibration photo.
|
||
3. App runs the Milestone 1 workflow on that calibration photo only: Mask → Length axis → Measure (length `L`, thickness, Calculate).
|
||
4. After Calculate, the app applies the approved mask sheet and sensitivity, and the same crop rules (3:4 portrait, 90% fill, transparent PNG, shorter-side floor), to every other photo in the batch.
|
||
5. App adds a second copy of the calibration inventory PNG with dimension overlays burned in (see Dimension overlay).
|
||
6. User sees Photos ready: inventory PNGs lined up in this order — clean calibration PNG, then the dimension-overlay copy of the calibration PNG, then the other batch photos in capture order — plus the Milestone 1 calibration details (widths, sqft, bdft, scale) presented as in Measure.
|
||
|
||
A batch of one photo still works: that photo is the calibration photo; the end set is the clean PNG plus the dimension-overlay copy.
|
||
|
||
## States (additions over Milestone 1)
|
||
|
||
1. Batch — add one or more photos; continue when the batch has at least one.
|
||
2. Pick calibration — user chooses which batch photo is the reference.
|
||
3. Mask / Length axis / Measure — Milestone 1 states on the calibration photo only.
|
||
4. Photos ready — lineup order: clean calibration PNG → dimension-overlay copy → other batch photos in capture order; plus Milestone 1 numbers.
|
||
|
||
Device draft restores the last approved state, including the batch and which photo was calibration when those exist.
|
||
|
||
## Apply to non-calibration photos
|
||
|
||
For each non-calibration photo:
|
||
|
||
- Reuse the approved Mask sheet (Auto / Green / Black) and sensitivity from the calibration photo. Do not re-open Mask controls for that photo in this milestone.
|
||
- Run background removal with those params; compose inventory PNG with the same crop rules as Milestone 1 Calculate.
|
||
- If a photo yields an empty mask or fails the PNG size floor, keep it out of the ready set and show a clear per-photo error; other photos still proceed.
|
||
|
||
Scale, widths, sqft, and bdft stay tied to the calibration photo and user `L` / thickness. Non-calibration photos are visual inventory only.
|
||
|
||
## Dimension overlay
|
||
|
||
A second copy of the **calibration** inventory PNG is added to the collection. Overlays are black, large enough to read on phone and storefront.
|
||
|
||
Orientation follows the **user-approved length axis** from Milestone 1 (not the upright edges of the photo).
|
||
|
||
- **Length:** dimension graphic beside the wood on the right in axis-space (outside the slab edge along the length direction).
|
||
- **Widths:** stations every 12 in along the approved length axis, starting 6 in from the **bottom** of the slab span, continuing while the station is not within 6 in of the top (stations at 6, 18, 30, … in inches along the axis while ≤ `L − 6`). Each width is drawn across the wood perpendicular to the length axis, with arrow tips on the left and right slab edges and the measurement text on that line.
|
||
- **Bottom:** after the calibration photo’s EXIF orientation is applied, the bottom edge of that oriented photo establishes which end of the slab is bottom for width stations. Length-axis direction still follows the user-approved Milestone 1 axis; EXIF only picks which end is bottom vs top along that span.
|
||
|
||
## Photos-ready order
|
||
|
||
1. Clean calibration inventory PNG
|
||
2. Dimension-overlay copy of the calibration PNG
|
||
3. Remaining batch inventory PNGs in capture order
|
||
|
||
The clean calibration PNG remains in the set. The annotated copy is extra.
|
||
|
||
## Acceptance
|
||
|
||
On a phone UAT build:
|
||
|
||
- User can capture 1–N photos, pick calibration, complete Milestone 1 on that shot, and see every successful batch photo as a 3:4 transparent inventory PNG lined up.
|
||
- Calibration measures match Milestone 1 presentation.
|
||
- Dimension-overlay copy of the calibration PNG is present with black length and width graphics oriented to the approved axis; width stations start 6 in from EXIF-established bottom.
|
||
- Lineup order is clean calibration → dimension overlay → other batch photos in capture order.
|
||
- No Woo create. No inference URL.
|
||
|
||
## Out of scope
|
||
|
||
- Complete-listing fields (SKU, species, category, edge, figure, grade, thickness band, moisture, `fig-*` / `feat-*`, title, short title, description, price)
|
||
- WooCommerce create (Milestone 3)
|
||
- Inference / Assist (Milestone 4)
|
||
- Changing Milestone 1 mask/axis/measure math except to reuse its outputs for batch apply and overlays
