# 📞 Props: Callbacks
|
||||||
|
|
||||||
|
| Prop | Signature | Description |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `onWatch` | `(state, durationMs, detail?) => void` | Initialization stage callback; `durationMs` is relative to this `init` start |
|
||||||
|
| `onPaintCallback` | `(payload: PaintCallbackPayload) => void` | Fires on successful paint, or when tapping a region without a brush selected |
|
||||||
|
| `onError` | `(message, error?) => void` | Segmentation or loading failure |
|
||||||
|
|
||||||
|
## PaintCallbackPayload
|
||||||
|
|
||||||
|
(Discriminated union, distinguished by `payload.kind`):
|
||||||
|
|
||||||
|
```ts
|
||||||
|
// Successful paint
|
||||||
|
{
|
||||||
|
kind: 'painted';
|
||||||
|
regionId: number;
|
||||||
|
regionName: string;
|
||||||
|
color: BgrColor;
|
||||||
|
configJson?: Record<string, unknown>; // from setPaintColor / initialPaintConfigJson
|
||||||
|
}
|
||||||
|
|
||||||
|
// Tapped a valid region without selecting a brush (no paint performed)
|
||||||
|
{
|
||||||
|
kind: 'brush_required';
|
||||||
|
hint: string; // e.g. "Please select a brush color first (bottom color bar or ref.setPaintColor)"
|
||||||
|
regionId: number;
|
||||||
|
regionName: string;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
onPaintCallback={payload => {
|
||||||
|
if (payload.kind === 'brush_required') {
|
||||||
|
showToast(payload.hint);
|
||||||
|
return;
|
||||||
|
}
|
||||||
|
savePaintRecord(payload.regionId, payload.color, payload.configJson);
|
||||||
|
}}
|
||||||
|
```
|
||||||
|
|
||||||
|
## onWatch detail (MaskSegmentWatchDetail)
|
||||||
|
|
||||||
|
| Field | Type | Description |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `regionCount` | `number` | Current effective region count |
|
||||||
|
| `maskPathsReady` | `boolean` | Whether outline Skia paths are ready |
|
||||||
|
| `freqLayersReady` | `boolean` | Whether frequency Shader textures are ready |
|
||||||
|
| `errorMessage` | `string` | Failure description in `error` state |
|
||||||
|
|
||||||
|
### onWatch State Flow
|
||||||
|
|
||||||
|
```
|
||||||
|
init
|
||||||
|
→ images_loaded Origin + mask read complete
|
||||||
|
→ mask_aligned Mask dimensions aligned
|
||||||
|
→ mask_sampled Mask pixel sampling complete
|
||||||
|
→ regions_ready Region extraction succeeded
|
||||||
|
→ layers_ready Paint texture layers ready (detail.maskPathsReady may still be false)
|
||||||
|
→ interactive Interactive (can tap regions, select colors, paint)
|
||||||
|
→ mask_paths_ready Outline paths ready (carousel dashed outlines can display; detail.maskPathsReady is true)
|
||||||
|
→ error Failure (detail.errorMessage has description)
|
||||||
|
```
|
||||||
|
|
||||||
|
`layers_ready` / `interactive` may fire before outline paths finish computing. If the host dismisses a blocking loader at `interactive`, the user can already operate; carousel dashed outlines appear automatically after `mask_paths_ready`.

|
## MaskSemanticColor Structure
|
||||||
|
|
||||||
|
```ts
|
||||||
|
{
|
||||||
|
name: string; // Semantic name, e.g. wall / ceiling / baseboard
|
||||||
|
hex: string; // Display hex color
|
||||||
|
bgr: { b: number; g: number; r: number }; // Must match mask pixel BGR channels
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Built-in palette: `MASK_SEMANTIC_COLORS` (see `src/utils/maskSemanticPalette.ts`).

| `setMaskConfig` | `(config) => void` | Update mask config at runtime and **re-segment** |
|
||||||
|
| `clearAllPaint` | `() => void` | Clear all paint records |
|
||||||

## SavePaintResult
|
||||||
|
|
||||||
|
`{ filePath, width, height, paintedCount, previewPath? }`
|
||||||
|
|
||||||
|
## Code Examples
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
const ref = useRef<MaskSegmentCanvasRef>(null);
|
||||||
|
|
||||||
|
ref.current?.reset();
|
||||||
|
ref.current?.swap(); // toggle
|
||||||
|
ref.current?.swap(true); // force show origin
|
||||||
|
|
||||||
|
const result = await ref.current?.save({ destDir: '/path/to/dir' });
|
||||||
|
|
||||||
|
const session = ref.current?.session();
|
||||||
|
ref.current?.loadSession(session);
|
||||||
|
|
||||||
|
ref.current?.setPaintColor({ b: 100, g: 120, r: 140 }, { sku: 'paint-001' });
|
||||||
|
ref.current?.setMaskConfig({ semanticColors: customColors });
|
||||||
|
|
||||||
|
ref.current?.clearAllPaint();
|
||||||
|
await ref.current?.resegment();
|
||||||
|
|
||||||
|
const regions = ref.current?.getRegions();
|
||||||
|
const painted = ref.current?.getPaintedRegions();
|
||||||
|
```
|
||||||
|
|
||||||
|
> `save` depends on the working buffer and pickMap being ready (typically after `interactive`); throws `'Image not ready, cannot save'` if not ready.

## 📊 State Variables
|
||||||
|
|
||||||
|
| State | Type | Purpose |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `imagePaths` | `{ origin, mask } \| null` | Local/remote image paths resolved by the host |
|
||||||
|
| `pathsError` | `string` | Error message when path resolution or PNG pre-warming fails |
|
||||||
|
| `watchState` | `MaskSegmentWatchState \| ''` | Initialization stage reported by `onWatch` |
|
||||||
|
| `isInteractive` | derived | `true` when `interactive` or `mask_paths_ready` — operations are allowed |
|
||||||
|
| `isOutlineReady` | derived | `true` when `mask_paths_ready` — carousel dashed outlines are ready |
|
||||||
|
| `isCanvasLoading` | derived | Canvas init is blocking (not including PNG path waiting) |
|
||||||
|
| `errorMessage` | `string` | Segmentation/loading failure message written by `onError` |
|
||||||
|
| `sessionDraft` | `MaskSegmentSession \| null` | Draft restored from MMKV or similar storage |
|
||||||
|
|
||||||

|
||||||

||||||
|
## ⚙️ Choosing Configuration Values
|
||||||
|
|
||||||
|
| Config | Use top-level prop when... | Use nested Config when... |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| Semantic colors | `semanticColors={...}` for most cases | `maskConfig.semanticColors` when paired with other mask params |
|
||||||
|
| Outline color | `regionOutlineColor="..."` for most cases | `paintConfig.regionOverlayFill` when also customizing the brush palette |
|
||||||
|
| Black threshold, max regions | — | `maskConfig` |
|
||||||
|
| Image processing size | — | `pipelineConfig` |
|
||||||
|
| Flash interval, tap tolerance | — | `interactionConfig` |
|
||||||
|
|
||||||
|
Top-level props and nested Configs **can coexist**; top-level `semanticColors` / `regionOutlineColor` take priority.
|
||||||

## 🔄 watchState & UI Guidance
|
||||||
|
|
||||||
|
```ts
|
||||||
|
// Blocking loading (before regions + paint layers are ready)
|
||||||
|
const isLoading = ![
|
||||||
|
'interactive',
|
||||||
|
'mask_paths_ready',
|
||||||
|
'error',
|
||||||
|
'',
|
||||||
|
].includes(watchState);
|
||||||
|
|
||||||
|
// Allow tapping regions, selecting colors, painting
|
||||||
|
const canOperate =
|
||||||
|
watchState === 'interactive' || watchState === 'mask_paths_ready';
|
||||||
|
|
||||||
|
// Carousel dashed outlines are fully ready
|
||||||
|
const isOutlineReady = watchState === 'mask_paths_ready';
|
||||||
|
|
||||||
|
// Show error screen
|
||||||
|
const hasError = watchState === 'error';
|
||||||
|
```
|
||||||
|
|
||||||
|
At `interactive`, `detail.maskPathsReady` is typically `false`; at `mask_paths_ready`, it is `true`. The gap is roughly ~100ms (async Skia path construction) and does not block tap-to-paint.
|
||||||
|
|
||||||
|
`originUrl` / `maskUrl` support:
|
||||||
|
|
||||||
|
- Local paths: `file:///...` or absolute paths
|
||||||
|
- Remote URLs: `http(s)://...` (the component handles download and decoding internally)
|
||||||
|
|
||||||
|
> Legacy props `originImgPath` / `maskImgPath` are deprecated; use `originUrl` / `maskUrl` instead.

# 🎨 Custom Semantic Color Table
|
||||||
|
|
||||||
|
Define custom semantic colors when your mask uses different color values:
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
const gymColors: MaskSemanticColor[] = [
|
||||||
|
{ name: 'wall', hex: '#4363D8', bgr: { b: 216, g: 99, r: 67 } },
|
||||||
|
{ name: 'ceiling', hex: '#3CB44B', bgr: { b: 75, g: 180, r: 60 } },
|
||||||
|
// ...
|
||||||
|
];
|
||||||
|
|
||||||
|
<MaskSegmentCanvas
|
||||||
|
semanticColors={gymColors}
|
||||||
|
maskConfig={{ blackThreshold: 30, maxRegionColors: 6 }}
|
||||||
|
/>
|
||||||
|
```
|
||||||
|
|
||||||
|
:::caution
|
||||||
|
`semanticColors` must match the semantic colors used in the backend/labeled mask; mismatch will cause recognition drift.

```tsx

|
const draft = JSON.parse(mmkv.getString('paint_draft'));
|
||||||
|
|
||||||
|
<MaskSegmentCanvas
|
||||||

Use `ref.session()` to export the current session and store it in MMKV or AsyncStorage for later recovery.

# 🔥 Pre-warm PNG Cache (Recommended)
|
||||||
|
|
||||||
|
Pre-warm the PNG decode cache before mounting the canvas to save **100–250ms** on initialization.
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
import { prewarmPngBgrCacheAsync } from 'react-native-mask-segment-canvas';
|
||||||
|
|
||||||
|
async function openPaintScreen(originUrl: string, maskUrl: string) {
|
||||||
|
await prewarmPngBgrCacheAsync([originUrl, maskUrl]);
|
||||||
|
navigation.navigate('Paint', { originUrl, maskUrl });
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Call `prewarmPngBgrCacheAsync` after download/extraction and before navigating to the paint screen for the best performance.

# 📦 Installation
|
||||||
|
|
||||||
|
## Peer Dependencies
|
||||||
|
|
||||||
|
Install these in your host project (versions should match your host RN version):
|
||||||
|
|
||||||
|
```bash
|
||||||
|
npm install @shopify/react-native-skia react-native-reanimated react-native-fast-opencv react-native-fs buffer upng-js react-native-gesture-handler
|
||||||
|
# If using showDebugPickers (photo library picker)
|
||||||
|
npm install react-native-image-picker
|
||||||
|
# Safe area insets
|
||||||
|
npm install react-native-safe-area-context
|
||||||
|
```
|
||||||
|
|
||||||
|
## Postinstall Setup
|
||||||
|
|
||||||
|
This library relies on `patch-package` to patch `react-native-fast-opencv`. Your host `package.json` must include:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"scripts": {
|
||||||
|
"postinstall": "patch-package"
|
||||||
|
},
|
||||||
|
"devDependencies": {
|
||||||
|
"patch-package": "^8.0.1"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
After installing this library, patches from `node_modules/react-native-mask-segment-canvas/patches/` are applied automatically during the host's `postinstall`.
|
||||||
|
|
||||||
|
## iOS / Android Native Dependencies
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd ios && pod install && cd ..
|
||||||
|
```
|
||||||
|
|
||||||
|
Ensure the host project has completed Skia, Reanimated, and OpenCV native setup per each library's documentation.
|
||||||
|
|
||||||
|
## Metro Configuration
|
||||||
|
|
||||||
|
When using `npm link`, a monorepo, or `file:` dependencies, add this library to `watchFolders` and use `extraNodeModules` + `blockList` to prevent duplicate module resolution:
|
||||||
|
|
||||||
|
```js
|
||||||
|
const path = require('path');
|
||||||
|
|
||||||
|
module.exports = {
|
||||||
|
watchFolders: [path.resolve(__dirname, '../MaskSegmentApp')],
|
||||||
|
resolver: {
|
||||||
|
nodeModulesPaths: [path.resolve(__dirname, 'node_modules')],
|
||||||
|
extraNodeModules: {
|
||||||
|
'react-native-reanimated': path.resolve(__dirname, 'node_modules/react-native-reanimated'),
|
||||||
|
'@shopify/react-native-skia': path.resolve(__dirname, 'node_modules/@shopify/react-native-skia'),
|
||||||
|
'react-native-gesture-handler': path.resolve(__dirname, 'node_modules/react-native-gesture-handler'),
|
||||||
|
'react-native-fast-opencv': path.resolve(__dirname, 'node_modules/react-native-fast-opencv'),
|
||||||
|
'react-native-safe-area-context': path.resolve(__dirname, 'node_modules/react-native-safe-area-context'),
|
||||||
|
'react-native-fs': path.resolve(__dirname, 'node_modules/react-native-fs'),
|
||||||
|
},
|
||||||
|
blockList: [
|
||||||
|
/\/MaskSegmentApp\/node_modules\/@shopify\/react-native-skia\//,
|
||||||
|
/\/MaskSegmentApp\/node_modules\/react-native-reanimated\//,
|
||||||
|
/\/MaskSegmentApp\/node_modules\/react-native-fast-opencv\//,
|
||||||
|
/\/MaskSegmentApp\/node_modules\/react-native-gesture-handler\//,
|
||||||
|
/\/MaskSegmentApp\/node_modules\/react-native-safe-area-context\//,
|
||||||
|
/\/MaskSegmentApp\/node_modules\/react-native-fs\//,
|
||||||
|
],
|
||||||
|
},
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
**Strongly recommended** — add this at the very top of the host `index.js` (before any business code):
|
||||||
|
|
||||||
|
```js
|
||||||
|
import '@shopify/react-native-skia';
|
||||||
|
```
|
||||||
|
|
||||||
|
See `example/metro.config.js` and `example/index.js` for the complete configuration with all peer singleton packages.
|
||||||
|
|
||||||
|
## Troubleshooting: Duplicate Module Errors
|
||||||
|
|
||||||
|
Common symptoms:
|
||||||
|
|
||||||
|
- `SkiaPictureView must be a function (received 'undefined')`
|
||||||
|
- `createAnimatedNode: Animated node[...] already exists`
|
||||||
|
|
||||||
|
These are almost always caused by Metro resolving multiple copies of reanimated / skia / gesture-handler / fast-opencv / safe-area packages.
|
||||||
|
|
||||||
|
**Best practice:**
|
||||||
|
|
||||||
|
1. Copy the `singletonPackages` + `extraNodeModules` + `blockList` pattern from `example/metro.config.js`
|
||||||
|
2. At the top of your `index.js`, import gesture-handler → reanimated → skia in order
|
||||||
|
3. Restart Metro with `--reset-cache` and reinstall the app
|
||||||
|
|
||||||
|
See the example project for a detailed checklist and template.

# 🎮 Interaction Guide
|
||||||
|
|
||||||
|
1. 🔁 **Initial Carousel**: After regions are ready, each region's dashed outline flashes sequentially per `initRegionFlashMs` (default 1s); stops on first user touch.
|
||||||
|
2. 🔍 **Preview (no brush selected)**: Long-press a region to show dashed outline for the connected component under the touch point; tapping a black area shows no outline.
|
||||||
|
3. 🎨 **Paint (brush selected)**: Tap a color in the bottom color bar or call `ref.setPaintColor` (or preselect via `initialPaintColor`), then tap a region to paint; tapping the same region again overwrites the color.
|
||||||
|
4. 💬 **Tap without brush**: No paint is performed; `onPaintCallback` fires with `kind: 'brush_required'`, carrying a `hint` and target region info for the host to show a toast/modal prompting color selection.
|
||||||
|
5. ↩️ **Undo**: Bottom-left button or `ref.reset()`; steps backward through paint history one action at a time.
|
||||||
|
6. 👁️ **Compare with Origin**: Bottom-right button or `ref.swap()`; hides the paint layer to show the original image.

# 🎨 react-native-mask-segment-canvas
|
||||||
|
|
||||||
|
A React Native **0.79** interactive mask segmentation library. The core export is the `MaskSegmentCanvas` component, consumable via **npm package** or **npm link** from any React Native project.
|
||||||
|
|
||||||
|
- 🧠 **OpenCV** (`react-native-fast-opencv`): mask semantic layout, baseboard patching, region extraction
|
||||||
|
- 🖌️ **Skia RuntimeEffect (SkSL)**: single-pass full-screen shader blending original image + LAB low/high frequency texture color overlays
|
||||||
|
- ✂️ **Skia Path**: dashed outline highlights for regions
|
||||||
|
- 👆 **Interaction**: bottom color bar for brush selection (optional initialization) → tap a region to paint; tapping without a brush selected fires `onPaintCallback` with a hint; long-press without a brush previews the region's dashed outline
|
||||||
|
|
||||||
|
This repository serves as both the **library source** (`src/index.ts`) and a **self-test demo** (root `App.tsx`).
|
||||||
|
|
||||||
|
📌 **For the recommended integration demo, see the `example/` directory** — it uses only the public API, fully simulating how a consumer project would integrate (including `package.json`, Metro configuration, and a complete reference `App.tsx`).

## 🔭 Overview
|
||||||
|
|
||||||
|
`MaskSegmentCanvas` renders an original image with an overlaid semantic mask, allowing users to tap regions and apply colors. The pipeline:
|
||||||
|
|
||||||
|
1. 📥 **Load** the origin image and mask image (local `file://` or remote `http(s)://`)
|
||||||
|
2. 🧩 **Segment** the mask via OpenCV into semantic regions (walls, ceiling, baseboard, etc.)
|
||||||
|
3. 🎨 **Prepare** LAB frequency-layer textures via SkSL for realistic color blending
|
||||||
|
4. 📐 **Build** Skia dashed-outline paths for each region
|
||||||
|
5. 👆 **Interactive** — users select a brush color and tap regions to paint; paint layers preserve the underlying texture
|
||||||
|
6. 💾 **Save** the composited result as PNG; export a JSON session for draft recovery
|
||||||
|
|
||||||
|
The component emits `onWatch` state transitions through the pipeline so the host app can show appropriate loading states.

# 📝 Notes
|
||||||
|
|
||||||
|
- The mask image should be a semantic color-block image with the same dimensions as the origin (black background + solid-color regions). Pixels with `max(B,G,R) < blackThreshold` (default 30) are excluded from segmentation.
|
||||||
|
- OpenCV segmentation runs on the JS thread; very large images may cause frame drops. Use `pipelineConfig.maxImageLongSide` to cap processing resolution.
|
||||||
|
- iOS photo library access requires photo permissions (only needed when `showDebugPickers` is enabled).
|
||||||
|
- `semanticColors` must match the semantic colors used in the backend/labeled mask; mismatch will cause recognition drift.

# ⚡ Performance
|
||||||
|
|
||||||
|
The data below is based on the Demo test image (`assets/test/origin.png` **1080×1920**, 6 semantic regions), **default `pipelineConfig`**, and `onWatch` `durationMs` (measured from `init`). These are **empirical ranges**, not strict benchmarks; actual device results vary with CPU, storage, and RN version.
|
||||||
|
|
||||||
|
## Measured Reference (Dev Env + PNG Pre-warming)
|
||||||
|
|
||||||
|
The Demo calls `prewarmPngBgrCacheAsync([origin, mask])` before mounting the canvas, so PNG decoding hits the memory cache. Typical logs:
|
||||||
|
|
||||||
|
| Stage | watchState | Approx. Duration | Notes |
|
||||||
|
| --- | --- | --- | --- |
|
||||||
|
| Mask aligned | `mask_aligned` | ~160ms | Mask scaled to segmentation working resolution |
|
||||||
|
| Regions ready | `regions_ready` / `mask_sampled` | ~320ms | Layout scan + baseboard + pickMap |
|
||||||
|
| **Interactive** | `**interactive`** | **~320–450ms** | Can tap regions, select colors, Shader paint |
|
||||||
|
| Outlines ready | `mask_paths_ready` | ~430–550ms | ~100ms after `interactive`; carousel outlines can display |
|
||||||
|
|
||||||
|
`interactive` does **not wait** for outline paths; `mask_paths_ready` only affects the initial carousel and optional UI hints.
|
||||||
|
|
||||||
|
Same-image sub-step magnitudes (`__DEV__` logs, default pipeline):
|
||||||
|
|
||||||
|
| Sub-step | Approx. Duration | Working Resolution |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| OpenCV LAB high/low freq | ~10–40ms | 270×480 |
|
||||||
|
| High/low freq Skia textures | ~20–30ms | same |
|
||||||
|
| Layout scan + baseboard + pick table | ~90–120ms | 405×720 (1080p → longSide 720) |
|
||||||
|
| Full contour paths (async, non-blocking) | ~80–150ms | 270×480 |
|
||||||
|
|
||||||
|
## Resolution vs pipelineConfig
|
||||||
|
|
||||||
|
Compute-intensive steps are capped by **maximum long side limits** and do **not scale linearly with 4K/8K origin images**. **Full PNG decoding** still scales linearly with pixel count.
|
||||||
|
|
||||||
|
| Step | Config Key | 1080×1920 Actual Size | Scales with Origin Pixels |
|
||||||
|
| --- | --- | --- | --- |
|
||||||
|
| PNG decode | — | 1080×1920 × 2 images | **Yes** |
|
||||||
|
| Mask seg / pickMap | `maxImageLongSide: 720` | ~405×720 | **No** (fixed when long side >720) |
|
||||||
|
| Shader high/low freq | `paintFreqMaxLongSide: 480` | ~270×480 | **No** |
|
||||||
|
| Working area Skia origin | same as `maxImageLongSide` | ~405×720 | **No** |
|
||||||
|
| Dashed outlines | `maskPathMaxLongSide: 480` | ~270×480 | **No** (does not block `interactive`) |
|
||||||
|
|
||||||
|
## interactive Estimation (Default Pipeline)
|
||||||
|
|
||||||
|
| Origin Spec | Relative to 1080p Pixels | With PNG Pre-warm | Cold Start (no pre-warm) |
|
||||||
|
| --- | --- | --- | --- |
|
||||||
|
| 1080×1920 | 1× | **320–450ms** | **450–700ms** |
|
||||||
|
| 1440×2560 (2K) | ~1.8× | **400–550ms** | **600–900ms** |
|
||||||
|
| 3840×2160 (4K) | ~4× | **500–750ms** | **800–1200ms** |
|
||||||
|
| 7680×4320 (8K) | ~16× | **0.8–1.5s** | **1.5–3s+** |
|
||||||
|
|
||||||
|
> **`<300ms` interactive**: achievable on 1080p + pre-warm + default pipeline + high-end devices, but **optimistic** — do not treat as an all-device SLA.
|
||||||
|
|
||||||
|
## Device Tier (1080p, Default Pipeline)
|
||||||
|
|
||||||
|
Relative to the ~320ms dev-environment baseline:
|
||||||
|
|
||||||
|
| Tier | Relative Multiplier | Pre-warm `interactive` | Cold Start |
|
||||||
|
| --- | --- | --- | --- |
|
||||||
|
| Flagship iOS / new flagship Android | 0.8–1.2× | 300–450ms | 500–800ms |
|
||||||
|
| Mid-range Android | 1.5–2.5× | 500–800ms | 700ms–1.2s |
|
||||||
|
| Low-end Android (4GB, old SoC) | 2.5–4× | 800ms–1.3s | 1–2s+ |
|
||||||
|
|
||||||
|
Android overhead primarily comes from: JS ↔ OpenCV bridge, memory bandwidth/GC, Skia texture upload.
|
||||||
|
|
||||||
|
## Impact of Raising maxImageLongSide
|
||||||
|
|
||||||
|
Setting `pipelineConfig.maxImageLongSide` to **1280** (above the default 720) results in a segmentation working area of ~720×1280, roughly **3×** the pixel count of the 720 tier:
|
||||||
|
|
||||||
|
| Scenario | Default 720 | Raised to 1280 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| 1080p `interactive` (mid-range) | ~320–800ms | **500ms–1s+** |
|
||||||
|
| Segmentation / pickMap duration | ~90–120ms | ~250–350ms |
|
||||||
|
|
||||||
|
Higher precision for longer init time. To stay **`<500ms` interactive**, keep the default **720**; reduce to **640** if needed.
|
||||||
|
|
||||||
|
## Optimization Tips
|
||||||
|
|
||||||
|
1. 🚀 **PNG pre-warming (recommended)**: Call `prewarmPngBgrCacheAsync` after download/extraction and before navigating to the paint screen. Typically saves **100–250ms** (greatest benefit on low-end devices).
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
import { prewarmPngBgrCacheAsync } from 'react-native-mask-segment-canvas';
|
||||||
|
|
||||||
|
await prewarmPngBgrCacheAsync([originPath, maskPath]);
|
||||||
|
// Then mount MaskSegmentCanvas
|
||||||
|
```
|
||||||
|
|
||||||
|
2. ⏱️ **Loading timing**: Dismiss the blocking loader at `interactive`; optionally listen for `mask_paths_ready` for "outlines preparing" hints.
|
||||||
|
3. 🖼️ **Large images / low-end devices**: Keep default `maxImageLongSide: 720`; optionally lower `paintFreqMaxLongSide` to **360**.
|
||||||
|
4. 📷 **4K assets**: Downsample on the host side before passing in, or accept ~0.8–1.5s `interactive` (with pre-warm).
|
||||||
|
5. 🔍 **Observability**: Watch Metro logs for `[MaskSegment]`, `[⏱ ...]` prefixes and `onWatch` `durationMs`.

# 🚀 Quick Start (Dev Demo)
|
||||||
|
|
||||||
|
The root `App.tsx` is a full self-test demo that imports directly from `./src`.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd MaskSegmentApp
|
||||||
|
|
||||||
|
npm install
|
||||||
|
|
||||||
|
cd ios && bundle exec pod install && cd ..
|
||||||
|
|
||||||
|
npm start
|
||||||
|
|
||||||
|
# In another terminal
|
||||||
|
npm run ios
|
||||||
|
# or
|
||||||
|
npm run android
|
||||||
|
```
|
||||||
|
|
||||||
|
**To see how a consumer project integrates:** go to the `example/` directory and follow its `README.md`. It uses `import from 'react-native-mask-segment-canvas'` with standard `package.json` and Metro config, fully simulating a consumer environment.

# 🔧 Troubleshooting
|
||||||
|
|
||||||
|
## iOS pod install fails
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd ios
|
||||||
|
bundle install
|
||||||
|
bundle exec pod install --repo-update
|
||||||
|
```
|
||||||
|
|
||||||
|
## Android build errors
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd android && ./gradlew clean && cd ..
|
||||||
|
```
|
||||||
|
|
||||||
|
## Segmentation fails / zero regions
|
||||||
|
|
||||||
|
- Verify `originUrl` / `maskUrl` are accessible
|
||||||
|
- Confirm mask semantic colors match the `semanticColors` config
|
||||||
|
- Check Metro logs for `[MaskSegment]` / `[⏱ ...]` output
|
||||||
|
|
||||||
|
## Dashed outlines misaligned / extra contours
|
||||||
|
|
||||||
|
- Outlines are generated from mask pixel external contours; long-press only shows the connected component at the touch point
|
||||||
|
- The initial carousel only shows the largest connected component for each semantic region
|
||||||
|
|
||||||
|
## Common Duplicate Module Errors
|
||||||
|
|
||||||
|
**Symptoms:**
|
||||||
|
- `SkiaPictureView must be a function (received 'undefined')`
|
||||||
|
- `createAnimatedNode: Animated node[...] already exists`
|
||||||
|
|
||||||
|
**Solution:**
|
||||||
|
1. Copy the `singletonPackages` + `extraNodeModules` + `blockList` pattern from `example/metro.config.js`
|
||||||
|
2. At the top of your `index.js`, import gesture-handler → reanimated → skia in order
|
||||||
|
3. Restart Metro with `--reset-cache` and reinstall the app

# 📞 Props：回调
|
||||||
|
|
||||||
|
| Prop | 签名 | 描述 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `onWatch` | `(state, durationMs, detail?) => void` | 初始化阶段回调；`durationMs` 从本次 `init` 开始计时 |
|
||||||
|
| `onPaintCallback` | `(payload: PaintCallbackPayload) => void` | 成功上色时触发，或未选择画笔时点击区域触发 |
|
||||||
|
| `onError` | `(message, error?) => void` | 分割或加载失败 |
|
||||||
|
|
||||||
|
## PaintCallbackPayload
|
||||||
|
|
||||||
|
（可辨识联合类型，通过 `payload.kind` 区分）：
|
||||||
|
|
||||||
|
```ts
|
||||||
|
// 成功上色
|
||||||
|
{
|
||||||
|
kind: 'painted';
|
||||||
|
regionId: number;
|
||||||
|
regionName: string;
|
||||||
|
color: BgrColor;
|
||||||
|
configJson?: Record<string, unknown>; // 来自 setPaintColor / initialPaintConfigJson
|
||||||
|
}
|
||||||
|
|
||||||
|
// 点击了有效区域但未选择画笔（未执行上色）
|
||||||
|
{
|
||||||
|
kind: 'brush_required';
|
||||||
|
hint: string; // 如 "请先选择画笔颜色（底部颜色条或 ref.setPaintColor）"
|
||||||
|
regionId: number;
|
||||||
|
regionName: string;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
示例：
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
onPaintCallback={payload => {
|
||||||
|
if (payload.kind === 'brush_required') {
|
||||||
|
showToast(payload.hint);
|
||||||
|
return;
|
||||||
|
}
|
||||||
|
savePaintRecord(payload.regionId, payload.color, payload.configJson);
|
||||||
|
}}
|
||||||
|
```
|
||||||
|
|
||||||
|
## onWatch detail（MaskSegmentWatchDetail）
|
||||||
|
|
||||||
|
| 字段 | 类型 | 描述 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `regionCount` | `number` | 当前有效区域数 |
|
||||||
|
| `maskPathsReady` | `boolean` | 轮廓 Skia 路径是否就绪 |
|
||||||
|
| `freqLayersReady` | `boolean` | 频域 Shader 纹理是否就绪 |
|
||||||
|
| `errorMessage` | `string` | `error` 状态下的失败描述 |
|
||||||
|
|
||||||
|
### onWatch 状态流转
|
||||||
|
|
||||||
|
```
|
||||||
|
init
|
||||||
|
→ images_loaded 原始图像和遮罩读取完成
|
||||||
|
→ mask_aligned 遮罩尺寸对齐
|
||||||
|
→ mask_sampled 遮罩像素采样完成
|
||||||
|
→ regions_ready 区域提取成功
|
||||||
|
→ layers_ready 上色纹理层就绪（detail.maskPathsReady 可能仍为 false）
|
||||||
|
→ interactive 可交互（可以点击区域、选择颜色、上色）
|
||||||
|
→ mask_paths_ready 轮廓路径就绪（轮播虚线轮廓可显示；detail.maskPathsReady 为 true）
|
||||||
|
→ error 失败（detail.errorMessage 包含描述）
|
||||||
|
```
|
||||||
|
|
||||||
|
`layers_ready` / `interactive` 可能在轮廓路径计算完成之前触发。如果宿主在 `interactive` 时关闭阻塞加载器，用户已可操作；轮播虚线轮廓在 `mask_paths_ready` 后自动显示。

|
| 状态 | 类型 | 用途 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `imagePaths` | `{ origin, mask } \| null` | 宿主解析后的本地/远程图片路径 |
|
||||||
|
| `pathsError` | `string` | 路径解析或 PNG 预热失败时的错误信息 |
|
||||||
|
| `watchState` | `MaskSegmentWatchState \| ''` | `onWatch` 上报的初始化阶段 |
|
||||||
|
| `isInteractive` | 派生值 | `interactive` 或 `mask_paths_ready` 时为 `true` — 允许操作 |
|
||||||
|
| `isOutlineReady` | 派生值 | `mask_paths_ready` 时为 `true` — 轮播虚线轮廓已就绪 |
|
||||||
|
| `isCanvasLoading` | 派生值 | Canvas 初始化阻塞中（不包括等待 PNG 路径） |
|
||||||
|
| `errorMessage` | `string` | `onError` 写入的分割/加载失败信息 |
|
||||||
|
| `sessionDraft` | `MaskSegmentSession \| null` | 从 MMKV 或类似存储恢复的草稿 |

## ⚙️ 选择配置值
|
||||||
|
|
||||||
|
| 配置 | 使用顶层 prop 的场景 | 使用嵌套 Config 的场景 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| 语义颜色 | `semanticColors={...}` 多数情况使用 | `maskConfig.semanticColors` 与其他遮罩参数配合使用时 |
|
||||||
|
| 轮廓颜色 | `regionOutlineColor="..."` 多数情况使用 | `paintConfig.regionOverlayFill` 同时自定义画笔调色板时 |
|
||||||
|
| 黑色阈值、最大区域数 | — | `maskConfig` |
|
||||||
|
| 图像处理尺寸 | — | `pipelineConfig` |
|
||||||
|
| 闪烁间隔、点击容差 | — | `interactionConfig` |
|
||||||
|
|
||||||
|
顶层 props 和嵌套 Configs **可以共存**；顶层 `semanticColors` / `regionOutlineColor` 优先级更高。

## 🔄 watchState 与 UI 引导
|
||||||
|
|
||||||
|
```ts
|
||||||
|
// 阻塞加载（区域和上色层就绪之前）
|
||||||
|
const isLoading = ![
|
||||||
|
'interactive',
|
||||||
|
'mask_paths_ready',
|
||||||
|
'error',
|
||||||
|
'',
|
||||||
|
].includes(watchState);
|
||||||
|
|
||||||
|
// 允许点击区域、选择颜色、上色（无需等待轮廓路径）
|
||||||
|
const canOperate =
|
||||||
|
watchState === 'interactive' || watchState === 'mask_paths_ready';
|
||||||
|
|
||||||
|
// 轮播虚线轮廓已完全就绪（可选 — 可关闭"轮廓准备中"提示）
|
||||||
|
const isOutlineReady = watchState === 'mask_paths_ready';
|
||||||
|
|
||||||
|
// 显示错误界面
|
||||||
|
const hasError = watchState === 'error';
|
||||||
|
```
|
||||||
|
|
||||||
|
`interactive` 状态下，`detail.maskPathsReady` 通常为 `false`；`mask_paths_ready` 状态下为 `true`。间隔约 100ms（异步 Skia 路径构建），不阻塞点击上色。
|
||||||
|
|
||||||
|
`originUrl` / `maskUrl` 支持：
|
||||||
|
|
||||||
|
- 本地路径：`file:///...` 或绝对路径
|

# 🎨 自定义语义颜色表
|
||||||
|
|
||||||
|
当遮罩使用不同的颜色值时，可以定义自定义语义颜色：
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
const gymColors: MaskSemanticColor[] = [
|
||||||
|
{ name: 'wall', hex: '#4363D8', bgr: { b: 216, g: 99, r: 67 } },
|
||||||
|
{ name: 'ceiling', hex: '#3CB44B', bgr: { b: 75, g: 180, r: 60 } },
|
||||||
|
// ...
|
||||||
|
];
|
||||||
|
|
||||||
|
<MaskSegmentCanvas
|
||||||
|
semanticColors={gymColors}
|
||||||
|
maskConfig={{ blackThreshold: 30, maxRegionColors: 6 }}
|
||||||
|
/>
|
||||||
|
```
|
||||||
|
|
||||||
|
:::caution
|
||||||
|
`semanticColors` 必须与后端/标注遮罩中使用的语义颜色匹配；不匹配会导致识别偏差。

# 🔥 PNG 缓存预热（推荐）
|

|
|
||||||
|
在挂载 Canvas 前预热 PNG 解码缓存，可节省 **100–250ms** 的初始化时间。
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
import { prewarmPngBgrCacheAsync } from 'react-native-mask-segment-canvas';
|
||||||
|
|
||||||
|
async function openPaintScreen(originUrl: string, maskUrl: string) {
|
||||||
|
await prewarmPngBgrCacheAsync([originUrl, maskUrl]);
|
||||||
|
navigation.navigate('Paint', { originUrl, maskUrl });
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
在下载/提取图片后、导航到上色界面前调用 `prewarmPngBgrCacheAsync` 可获得最佳性能。

# 📦 安装
|
||||||
|
|
||||||
|
## Peer 依赖
|
||||||
|
|
||||||
|
在宿主项目中安装以下依赖（版本应与宿主 RN 版本匹配）：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
npm install @shopify/react-native-skia react-native-reanimated react-native-fast-opencv react-native-fs buffer upng-js react-native-gesture-handler
|
||||||
|
# 如果使用 showDebugPickers（相册选择器）
|
||||||
|
npm install react-native-image-picker
|
||||||
|
# 安全区域边距
|
||||||
|
npm install react-native-safe-area-context
|
||||||
|
```
|
||||||
|
|
||||||
|
## 安装后设置
|
||||||
|
|
||||||
|
本库依赖 `patch-package` 来修补 `react-native-fast-opencv`。宿主项目的 `package.json` 必须包含：
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"scripts": {
|
||||||
|
"postinstall": "patch-package"
|
||||||
|
},
|
||||||
|
"devDependencies": {
|
||||||
|
"patch-package": "^8.0.1"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
安装本库后，`node_modules/react-native-mask-segment-canvas/patches/` 中的补丁将在宿主 `postinstall` 期间自动应用。
|
||||||
|
|
||||||
|
## iOS / Android 原生依赖
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd ios && pod install && cd ..
|
||||||
|
```
|
||||||
|
|
||||||
|
确保宿主项目已按照各库文档完成 Skia、Reanimated 和 OpenCV 的原生设置。
|
||||||
|
|
||||||
|
## Metro 配置
|
||||||
|
|
||||||
|
使用 `npm link`、monorepo 或 `file:` 依赖时，请将本库添加到 `watchFolders`，并使用 `extraNodeModules` + `blockList` 防止重复模块解析：
|
||||||
|
|
||||||
|
```js
|
||||||
|
const path = require('path');
|
||||||
|
|
||||||
|
module.exports = {
|
||||||
|
watchFolders: [path.resolve(__dirname, '../MaskSegmentApp')],
|
||||||
|
resolver: {
|
||||||
|
nodeModulesPaths: [path.resolve(__dirname, 'node_modules')],
|
||||||
|
extraNodeModules: {
|
||||||
|
'react-native-reanimated': path.resolve(__dirname, 'node_modules/react-native-reanimated'),
|
||||||
|
'@shopify/react-native-skia': path.resolve(__dirname, 'node_modules/@shopify/react-native-skia'),
|
||||||
|
'react-native-gesture-handler': path.resolve(__dirname, 'node_modules/react-native-gesture-handler'),
|
||||||
|
'react-native-fast-opencv': path.resolve(__dirname, 'node_modules/react-native-fast-opencv'),
|
||||||
|
'react-native-safe-area-context': path.resolve(__dirname, 'node_modules/react-native-safe-area-context'),
|
||||||
|
'react-native-fs': path.resolve(__dirname, 'node_modules/react-native-fs'),
|
||||||
|
},
|
||||||
|
blockList: [
|
||||||
|
/\/MaskSegmentApp\/node_modules\/@shopify\/react-native-skia\//,
|
||||||
|
/\/MaskSegmentApp\/node_modules\/react-native-reanimated\//,
|
||||||
|
/\/MaskSegmentApp\/node_modules\/react-native-fast-opencv\//,
|
||||||
|
/\/MaskSegmentApp\/node_modules\/react-native-gesture-handler\//,
|
||||||
|
/\/MaskSegmentApp\/node_modules\/react-native-safe-area-context\//,
|
||||||
|
/\/MaskSegmentApp\/node_modules\/react-native-fs\//,
|
||||||
|
],
|
||||||
|
},
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
**强烈推荐** — 在宿主 `index.js` 最顶部（任何业务代码之前）添加：
|
||||||
|
|
||||||
|
```js
|
||||||
|
import '@shopify/react-native-skia';
|
||||||
|
```
|
||||||
|
|
||||||
|
完整的配置（含所有 peer singleton 包）请参考 `example/metro.config.js` 和 `example/index.js`。
|
||||||
|
|
||||||
|
## 故障排除：重复模块错误
|
||||||
|
|
||||||
|
常见症状：
|
||||||
|
|
||||||
|
- `SkiaPictureView must be a function (received 'undefined')`
|
||||||
|
- `createAnimatedNode: Animated node[...] already exists`
|
||||||
|
|
||||||
|
这些问题几乎都是由于 Metro 解析了多份 reanimated / skia / gesture-handler / fast-opencv / safe-area 包副本导致的。
|
||||||
|
|
||||||
|
**最佳实践：**
|
||||||
|
|
||||||
|
1. 从 `example/metro.config.js` 复制 `singletonPackages` + `extraNodeModules` + `blockList` 模式
|
||||||
|
2. 在 `index.js` 顶部按顺序导入 gesture-handler → reanimated → skia
|
||||||
|
3. 使用 `--reset-cache` 重启 Metro 并重新安装应用
|
||||||
|
|
||||||
|
详细清单和模板请参阅示例项目。

1. 🔁 **初始轮播**：区域就绪后，每个区域的虚线轮廓按 `initRegionFlashMs`（默认 1s）依次闪烁；首次用户触摸时停止。
|
||||||
|
2. 🔍 **预览（未选择画笔）**：长按区域可显示触摸点下连通分量的虚线轮廓；点击黑色区域不显示轮廓。
|
||||||
|
3. 🎨 **上色（已选择画笔）**：点击底部颜色条中的颜色或调用 `ref.setPaintColor`（或通过 `initialPaintColor` 预设），然后点击区域上色；再次点击同一区域会覆盖颜色。
|
||||||
|
4. 💬 **无画笔点击**：不执行上色；`onPaintCallback` 触发 `kind: 'brush_required'`，携带提示信息和目标区域信息，供宿主显示 Toast/弹窗提示选择颜色。
|
||||||
|
5. ↩️ **撤销**：左下按钮或 `ref.reset()`；按上色历史逐步后退。
|
||||||
|
6. 👁️ **与原图对比**：右下按钮或 `ref.swap()`；隐藏上色层以显示原图。

|
|
||||||
|
一个 React Native **0.79** 交互式遮罩分割库。核心导出为 `MaskSegmentCanvas` 组件，可通过 **npm 包** 或 **npm link** 在任何 React Native 项目中使用。
|
||||||
|
|
||||||
|
- 🧠 **OpenCV** (`react-native-fast-opencv`)：遮罩语义布局、踢脚线修补、区域提取
|
||||||
|
- 🖌️ **Skia RuntimeEffect (SkSL)**：单 Pass 全屏着色器，混合原图 + LAB 低频/高频纹理颜色叠加
|
||||||
|
- ✂️ **Skia Path**：区域虚线轮廓高亮
|
||||||
|
- 👆 **交互**：底部颜色条选择画笔（可选初始化）→ 点击区域上色；未选择画笔时点击会触发 `onPaintCallback` 并附带提示；未选画笔时长按可预览区域的虚线轮廓
|
||||||
|
|
||||||
|
本仓库同时作为 **库源码**（`src/index.ts`）和 **自测 Demo**（根目录 `App.tsx`）。
|
||||||
|
|
||||||
|
📌 **推荐的集成 Demo 请查看 `example/` 目录** — 该目录仅使用公开 API，完全模拟消费方项目的集成方式（包括 `package.json`、Metro 配置和完整的参考 `App.tsx`）。

## 🔭 概述
|
||||||
|
|
||||||
|
`MaskSegmentCanvas` 渲染原始图像并叠加语义遮罩，允许用户点击区域并应用颜色。处理流程：
|
||||||
|
|
||||||
|
1. 📥 **加载**原始图像和遮罩图像（本地 `file://` 或远程 `http(s)://`）
|
||||||
|
2. 🧩 **分割**通过 OpenCV 将遮罩分割为语义区域（墙面、天花板、踢脚线等）
|
||||||
|
3. 🎨 **准备**通过 SkSL 生成 LAB 频域层纹理，实现逼真的颜色混合
|
||||||
|
4. 📐 **构建**每个区域的 Skia 虚线轮廓路径
|
||||||
|
5. 👆 **交互** — 用户选择画笔颜色并点击区域上色；上色层保留底层纹理
|
||||||
|
6. 💾 **保存**合成结果为 PNG；导出 JSON 会话用于草稿恢复
|
||||||
|
|
||||||
|
组件通过 `onWatch` 发出 Pipeline 状态转换，宿主应用可据此显示相应的加载状态。

# 📝 注意事项
|
||||||
|
|
||||||
|
- 遮罩图像应为与原始图像同尺寸的语义色块图（黑色背景 + 纯色区域）。`max(B,G,R) < blackThreshold`（默认 30）的像素将被排除在分割之外。
|
||||||
|
- OpenCV 分割在 JS 线程上运行；非常大的图像可能导致掉帧。使用 `pipelineConfig.maxImageLongSide` 限制处理分辨率。
|
||||||
|
- iOS 相册访问需要照片权限（仅在启用 `showDebugPickers` 时需要）。
|
||||||
|
- `semanticColors` 必须与后端/标注遮罩中使用的语义颜色匹配；不匹配会导致识别偏差。

## 提高 maxImageLongSide 的影响
|
||||||
|
|
||||||
|
将 `pipelineConfig.maxImageLongSide` 设为 **1280**（高于默认 720）会使分割工作区变为约 720×1280，像素数约为 720 档的 **3 倍**：
|
||||||
|
|
||||||
|
| 场景 | 默认 720 | 提高到 1280 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| 1080p `interactive`（中端设备） | ~320–800ms | **500ms–1s+** |
|
||||||
|
| 分割 / pickMap 耗时 | ~90–120ms | ~250–350ms |
|
||||||
|
|
||||||
|
更高精度带来更长的初始化时间。要保持在 **`<500ms` interactive**，保留默认 **720**；必要时可降至 **640**。
|
||||||
|
|
||||||
|
## 优化建议
|
||||||
|
|
||||||
|
1. 🚀 **PNG 预热（推荐）**：在下载/提取图片后、导航到上色界面前调用 `prewarmPngBgrCacheAsync`。通常可节省 **100–250ms**（低端设备收益最大）。
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
import { prewarmPngBgrCacheAsync } from 'react-native-mask-segment-canvas';
|
||||||
|
|
||||||
|
await prewarmPngBgrCacheAsync([originPath, maskPath]);
|
||||||
|
// 然后挂载 MaskSegmentCanvas
|
||||||
|
```
|
||||||
|
|
||||||
|
2. ⏱️ **加载时机**：在 `interactive` 时关闭阻塞加载器；可选监听 `mask_paths_ready` 以显示"轮廓准备中"提示。
|
||||||
|
3. 🖼️ **大图 / 低端设备**：保持默认 `maxImageLongSide: 720`；可选将 `paintFreqMaxLongSide` 降至 **360**。
|
||||||
|
4. 📷 **4K 素材**：在宿主侧先降采样再传入，或接受约 0.8–1.5s 的 `interactive`（含预热）。
|
||||||
|
5. 🔍 **可观测性**：观察 Metro 日志中的 `[MaskSegment]`、`[⏱ ...]` 前缀和 `onWatch` `durationMs`。

根目录 `App.tsx` 是一个完整的自测 Demo，直接从 `./src` 导入。
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd MaskSegmentApp
|
||||||
|
|
||||||
|
npm install
|
||||||
|
|
||||||
|
cd ios && bundle exec pod install && cd ..
|
||||||
|
|
||||||
|
npm start
|
||||||
|
|
||||||
|
# 在另一个终端中
|
||||||
|
npm run ios
|
||||||
|
# 或
|
||||||
|
npm run android
|
||||||
|
```
|
||||||
|
|
||||||
|
**查看消费方项目如何集成：** 进入 `example/` 目录并按照其中的 `README.md` 操作。它使用 `import from 'react-native-mask-segment-canvas'` 配合标准 `package.json` 和 Metro 配置，完全模拟消费方环境。

# 🔧 故障排除
|
||||||
|
|
||||||
|
## iOS pod install 失败
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd ios
|
||||||
|
bundle install
|
||||||
|
bundle exec pod install --repo-update
|
||||||
|
```
|
||||||
|
|
||||||
|
## Android 构建错误
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd android && ./gradlew clean && cd ..
|
||||||
|
```
|
||||||
|
|
||||||
|
## 分割失败 / 零区域
|
||||||
|
|
||||||
|
- 确认 `originUrl` / `maskUrl` 可访问
|
||||||
|
- 确认遮罩语义颜色与 `semanticColors` 配置匹配
|
||||||
|
- 检查 Metro 日志中的 `[MaskSegment]` / `[⏱ ...]` 输出
|
||||||
|
|
||||||
|
## 虚线轮廓错位 / 多余轮廓
|
||||||
|
|
||||||
|
- 轮廓从遮罩像素外部轮廓生成；长按仅显示触摸点下的连通分量
|
||||||
|
- 初始轮播仅显示每个语义区域的最大连通分量
|
||||||
|
|
||||||
|
## 常见重复模块错误
|
||||||
|
|
||||||
|
**症状：**
|
||||||
|
- `SkiaPictureView must be a function (received 'undefined')`
|
||||||
|
- `createAnimatedNode: Animated node[...] already exists`
|
||||||
|
|
||||||
|
**解决方案：**
|
||||||
|
1. 从 `example/metro.config.js` 复制 `singletonPackages` + `extraNodeModules` + `blockList` 模式
|
||||||
|
2. 在 `index.js` 顶部按顺序导入 gesture-handler → reanimated → skia
|
||||||
|
3. 使用 `--reset-cache` 重启 Metro 并重新安装应用
