The rail gains an HSL tab between FX and FRAME, and the tab opens the mixer ported from the web studio: eight hue bands, each with hue/sat/lum knobs on a -10..+10 ruler, plus three whole-image moves behind an IMAGE divider. Band weights are linear tents anchored on HSL_BANDS and summing to 1 at every hue, so neighbouring bands hand over at exactly half strength and no hue falls in a gap. Pixels under 8% saturation are gated out of the weights (rgb2hsl calls a neutral red, so an ungated one would ride the RED band), while the whole-image LUM move is added after the gate and still lifts a picture that -SAT has pulled to grey. The mixer runs last in TONE_SKSL, so a band edit is judged on the colour the user actually sampled. The eyedropper is library-only: PICK arms a layer over the picture, a tap reads the rendered pixel off the canvas, points the ruler at the nearest band and hangs a panel carrying that band's three knobs. A live preview has no pixel to read, so in camera mode the chip greys out - the mixer itself still runs there, which is why the camera worklet's tone buffer had to grow from 10 slots to 40: a missed slot would have pushed NaN into every uniform and taken the whole tone pass down, not just HSL. HSL is a LITE feature (the web studio builds it for guests too), and MONOCHROME switches the mixer off outright - a mono stock has no hue to select. Checked on a Xiaomi thor against an 8-band chart: +10 whole-image HUE rotates all eight bands by +30 deg, -10 on one band's SAT flattens that band and leaves the other seven alone, and a whole-image -SAT drops the camera preview's mean chroma 13.7 -> 0.4 with +LUM still lifting it 116 -> 166. Cut as 1.2.4 / versionCode 6.

## 1.2.4 (versionCode 6)
|
||
|
||
HSL
|
||
- New HSL tab in the tool rail: the web studio's 8-band selective colour mixer. Each band (RED, ORANGE, YELLOW, GREEN, AQUA, BLUE, PURPLE, MAGENTA) carries hue, saturation and lightness knobs, -10..+10; -10 on SAT is grey, full HUE is a 30 deg turn, full LUM is +0.25.
|
||
- Band weights are linear tents anchored on the 8 hues and summing to 1 at every hue, so neighbouring bands hand over at exactly half strength and no hue falls in a gap. Pixels under 8% saturation are gated out of the weights (rgb2hsl calls them red, and an ungated neutral would ride the RED band), while the whole-image LUM move is added after the gate, so a picture pulled to grey by -SAT still answers +LUM.
|
||
- The mixer runs last in TONE_SKSL, after split-tone/kv and vibrance, so a band edit is judged on the colour the user actually sampled.
|
||
- Library mode gains an eyedropper: PICK arms a layer over the picture, a tap reads the rendered pixel, points the ruler at the nearest band and hangs a panel with that band's three knobs. In camera mode PICK is greyed out - a live preview has no pixel to read - but the mixer still runs in the preview.
|
||
- HUE / SAT / LUM IMAGE move every hue at once, behind an IMAGE divider in the same chip row.
|
||
|
||
Rail
|
||
- Tool rail order: PRESETS, FAVORITED, WB, LIGHT, FX, HSL, FRAME.
|
||
|
||
Notes
|
||
- HSL is a LITE feature: both builds get it, no PRO gate.
|
||
- MONOCHROME disables the mixer outright - a mono stock has no hue to select.
|
||
- The camera worklet's tone buffer grew from 10 to 40 slots; a missed slot would have pushed NaN into every uniform and broken the whole tone pass, not just HSL.
|
||
- Measured on a Xiaomi thor against an 8-band chart: +10 whole-image HUE rotates all eight bands by exactly +30 deg, -10 on a band's SAT flattens that band to grey while the other seven stay put, and a whole-image -SAT drops the camera preview's mean chroma from 13.7 to 0.4 with +LUM still lifting it 116 -> 166.
|
||
|
||
## 1.2.3 (versionCode 5)
|
||
|
||
Shutter
|
||
- The shutter no longer waits on GPS: the fix is prewarmed at launch and bounded by a 2 s deadline, so a tagged shot reaches the gallery in about 3 s instead of 12–25 s.
|
||
- A shot pressed before the camera session binds is queued and replayed, not dropped.
|
||
- Fixes "Capture Failed — Could not take the photo.": `capturePhotoToFile` needs both its settings and options arguments.
|
||
- Saving to the gallery no longer depends on the media permission — the native save runs first, MediaLibrary only as a fallback.
|
||
|
||
Memory
|
||
- The Skia surface and bitmap are released after every export, dropping one full-resolution copy per rotation; the watermark font is parsed once.
|
||
|
||
Cold start
|
||
- The JS bundle is stored uncompressed in the APK.
|
||
- Named Lucide imports are rewritten to per-icon modules, so only the icons the app renders are bundled: 4.66 MB → 3.40 MB (−27%).
|
||
- The export pipeline and the recipe/GPS helpers load on demand.
|
||
- Hidden modals render nothing.
|
||
|
||
Measured on a vivo V2430 (Android 16) with a force-stop/start/tap probe: the earliest tap that reliably lands a photo moved from ~1.8 s to ~1.6 s once the bundle was trimmed. The rest is spent before app JS — process init, SoLoader, Hermes eval.
