Three WATERMARK/FRAME behaviours that share the stamp geometry:
* GPS mark: drag it anywhere on the frame/photo area and pinch it bigger or
smaller. The 0..1 anchor plus the size multiplier ride along in the export
options, so a framed file (whose canvas IS the card/frame) burns the mark in
at exactly the fraction the preview showed.
* The photo's own pinch zoom stays available while the WATERMARK editor is
closed, so a two-finger zoom is never swallowed by the mark while its panel
is open.
* WALL FRAME gains a WALL PORTRAIT / WALL LANDSCAPE chip: the artwork hangs
in its own 4000x3117 orientation instead of the default 90-degree rotation.
The highlight knee opened at 0.45, so dropping HIGHLIGHT pulled a mid-grey
down with the true highlights. It now opens at 0.65 (and the coefficient
drops 0.32 -> 0.22 to stay monotonic), so the slider leaves everything up to
a light grey untouched and still rolls the bright end off. Shadow is
untouched — its 0.00..0.55 knee was already right.
Switching between the library and the camera now drops the edits back to
the recipe's own values, no frame and no custom mark. A frame was picked
for the still it sat on and the mark was placed against that very photo, so
neither may follow the user across the switch (or into a live capture),
exactly like the sliders that were tuned on the photo in front of them.
Highlight/Shadow scaled R, G and B by one luma gain. That keeps the ratio
but crushes absolute chroma, so -SH turned a saturated blue into near-black
and -HL turned bright colours grey, and both sliders only bit at the very
ends of the range (knees 0.80..1.00 / 0.00..0.30) — they read as dead on
any photo without true whites or blacks.
The curve now moves the luma and carries the colour difference (rgb - luma)
along at clamp(gain, 0.55, 1.35), so hue survives darkening and lifting
instead of collapsing to black or white. Both knobs are pure additive luma
shifts with soft knees over the upper/lower half: the 0.50 midpoint moves
under 3%, and the curve stays monotonic (the old multiplicative form was
not — with hl=-1 a grey 0.73 came out darker than 0.80).
Kotlin applyTone port and the native bench probe gates follow.
Verified on device (4200x2800 probe: grey ramp + colour patches), library
export at ratio 4:3: -10 highlight leaves the darks alone and drops white
243->189 with the sky still blue; -10 shadow keeps blue as dark blue
(0,0,254)->(0,3,146), never black, ramp stays monotonic. Export keeps the
source 4200x2800 as well, so nothing is cropped.
The mark is placed against the library photo it was dragged on, but it
survived the switch to the live camera: the preview kept drawing it and
the next capture burned it in. Camera mode already drops the frame and
the library GPS for the same reason, so drop the accepted watermark too.
Resetting both the draft and the accepted copy keeps the chip honest and
stops the AsyncStorage session snapshot from restoring a camera mode
that still carries a library watermark.
A two-finger pinch only changes scale once the photo is already zoomed
in; at 100% the gesture is inert, so the paging strip keeps behaving
like a plain gallery. The responder is now held for the whole pinch so
the paging ScrollView cannot steal it mid-gesture.
The rail chips carried a lucide glyph before the label; drop the icons and
the icon field so the labels stand alone (the row is a plain text rail now,
and each chip is ~50px narrower). Also rename the FX knob from the
lens-vendor term to LIGHT GLOW - same key, same maths, just the label.
Mirror export pass 5b in the onFrame worklet: extract the highlights with
the same 2.5x-1.5 contrast curve, blur that selection, Screen it back at
0.15..0.5 alpha. The selection must be built as an image filter so the
highlight curve runs before the blur (a paint color filter would run after,
smearing the matrix into the selection).
Kept the tone/cinema path intact: the base draw now records the shader it
used and the glow pass reuses it (drawRect) or falls back to the plain
drawImage, so the glow always sits on the same processed pixels.
Measured on the Xiaomi 2203121C: 5 interleaved 0/10 pairs, the HDF=10 mean
luma is +0.70..0.84 above HDF=0 every time (AE metering does not track the
software pass, so the toggle is the only variable), and frame counts are
unchanged (488/489 vs 492/488 frames per 15s; GPU busy rises ~30%, still
inside the 3 ms median GPU frame). No fps loss, so the pass stays.
- FX: new VIGNETTING 0-10 control (chip + slider). Darkens the four
corners of the photo with a radial gradient whose radius is the photo
diagonal/2, so the falloff stays circular on any aspect. Applied in
preview (camera overlay, polaroid/wall window, plain library) and in
exportEngine pass 6b, always on the picture, never on the mat.
- LIGHT: new VIBRANCE -10..+10 (chroma-masked saturation in the tone
shader: vivid pixels move least). Renamed the existing saturation
control chip from COLOR to SATURATION - same param, clearer label.
- Fix: <Shader> takes a RuntimeEffect, not a gradient SkShader; the
preview vignette threw "Object is not a HostObject" when it got one.
Use the declarative <RadialGradient> child on the Rect instead.
- Preview: drop the "AE/AF LOCKED - TAP TO UNLOCK" banner; the lock
reticle is now itself the unlock touch target.
The custom watermark captured EVERY image touch whenever the chip was ON
with text, in both modes: after switching from a library photo to the
camera there was no way to give the image back to tap-to-focus, and a
frame picked for the still rode along onto the live preview (and into the
capture).
- AdjustPanel: CANCEL chip next to ACCEPT. It drops the un-accepted draft
and restores the last ACCEPTED mark (none if nothing was accepted).
- Viewfinder: draws the mark whenever the chip is ON with text, but only
lets it CAPTURE touches while its editor is open (new wmEditing prop).
A double-tap ON the mark still re-opens that editor from the library
viewer.
- App: ACCEPT and CANCEL now close the editor (that closes the placement
layer with it). Switching mode closes the deck panels, and leaves the
frame behind: camera mode has no FRAME picker to undo one.
Verified on device (9a6a7277): camera tap locks AE/AF with the watermark
left ON; library polaroid no longer appears on the live preview after the
switch; CANCEL reverts the chip to CUSTOM WATERMARK OFF and closes the
panel; ACCEPT closes it and the next capture embeds the mark (amber text
found at 0.5/0.375 of the 3000x4000 export), while a capture before
ACCEPT carries none.
The built-in lens filter, simulated the way it is done in Photoshop: pull the
highlights out with a hard contrast curve (out = 2.5*in - 1.5, black below 0.6),
Gaussian-blur that selection, then Screen it back over the photo at reduced
opacity. Screen against a near-black pixel is a no-op, so areas with no
highlight within the blur radius come back byte-identical while lit areas
spread their light.
One 0..10 knob drives both the radius (4%..1.9% of the width, ~10..50px at
2560 wide) and the opacity (0.15..0.5), matching the recipe's 15-50px radius
range. The extraction composes on top of the recipe colour matrix so a
monochrome look glows white instead of leaking the original colours back.
Runs in the Skia export engine only; the P5 native path is not wired into the
app (dev parity probe only), so it is left alone for now.
Watermark editing no longer covers the photo: the preview letterboxes the
image inside its fit rect while the deck is open, and the idle hint is gone.
The FRAME tab can rotate a library photo 90 degrees clockwise. Rotation
swaps the pixel dimensions instead of the frame, so the polaroid/wall window
keeps its aspect and every consumer (cover crop, watermark area, export) picks
up the new orientation from width()/height() with no extra layout branch. The
rotate surface is CPU-backed on purpose - a GPU snapshot loses its pixels
before the next frame and renders the photo black.
Custom watermark text can now be dragged anywhere on the photo, double-tapped
to re-edit, and is only baked into the file once ACCEPT is pressed; the export
engine takes the same position. It also gained COLOR/SIZE/FONT chips, with the
font list read from the OS via Skia's FontMgr so any installed family can be
used.
The framed windows (polaroid card / wall frame opening) now take the same pinch + double-tap gestures as plain library, clamped so the photo keeps covering the mat opening, and the visible sub-rectangle is handed to the export engine so the file matches the preview.
Wall frame export also stopped crashing: on Android release an image asset resolves to a drawable *name* ('wallframe') and is flagged downloaded, so Asset.downloadAsync short-circuited and readAsStringAsync threw 'Unsupported scheme for location wallframe'. Clearing that state lets the native module copy the drawable into the cache.
Edge-to-edge (edgeToEdgeEnabled) makes Android ignore the manifest's
adjustResize, so the IME never shrank the window and the text input sat
under the keyboard. Track keyboardDidShow/Hide height and pad the deck.
Restore shutter sound/metering/RAW from a dedicated key under both 'default'
and 'last session' startup (the session file only stores the look and is
written on background events, so it can be stale after a force-kill). Guard
the persist effect until hydration finishes so the mount-time defaults cannot
overwrite the stored values; drop the stale session override of these three.
Flip only reconfigured the CameraSession in place, leaving the Skia
offscreen-surface cache from the old lens wedged on this Xiaomi: after a
flip the preview banded then went black while the frame pipeline kept
delivering (heartbeat kept rising) and only a full app restart revived it.
- key <SkiaCamera> by facing + mount nonce so a flip fully unmounts and
remounts the camera (lib clears its surface cache on unmount), i.e. a
clean restart on every lens switch instead of an in-place reconfigure.
- watchdog now recovers by the same full remount instead of an isActive
toggle (which never revives a wedged preview), budgeted to 3 restarts.
- bump a re-render on every onStarted: after a remount cameraActive never
drops (no onStopped on unmount) so the reopen did not re-render and the
new controller was never re-read, leaving the 1x-10x zoom chips hidden
until the next touch.
Verified on device: 15+ flips with no wedge, chips visible immediately
after each flip, preview stays live (was ~5 min to black before).
- Settings STARTUP MODE chips (AsyncStorage startup_mode): default = clean camera
+ PROVIA neutral 4:3, last = restore full session look.
- initSession: resolve sim-* recipe ids via FILM_SIMS (fix clobber of session
ratio/adjustments to 4:3 canonical); restore via setSelectedRecipe not
applyRecipe so user tweaks (frame/geotag/ratio) survive restore.
- applyDefaultStartup turns GPS watermark OFF (user-requested default).
- Shutter: OFF must not play click on must-play-policy devices. VisionCamera
v5.2.3 HybridPhotoOutput.kt plays MediaActionSound itself gated by
(enableShutterSound ?: true) || mustPlayShutterSound — on Xiaomi mustPlay=true
so OFF still clicked. Both capture paths now gate on enableShutterSound != false.
node_modules patch not trackable -> artifacts/patches/vision-camera-shutter-silent.patch.
Verified on Xiaomi 12S Ultra: log SND user=false -> play=false; cold-start
DEFAULT shows GPS WATERMARK OFF.
Local Kotlin module modules/recipescam-export (autolinked via expo ./modules)
exposes decodeEncodeAsync — BitmapFactory decode -> JPEG q95 encode -> file,
all on Dispatchers.IO off the JS/main threads. EXPO_PUBLIC_BENCH=1 builds run
src/dev/nativeBenchProbe.ts: 3 timed decode+encode passes on the bundled
wallframe artwork plus a JS-timer gap check proving the JS thread never
blocks during native rendering. Legacy Skia engine untouched (reference).
