When you save, your app will automatically update and reflect these changes — this is powered by [Fast Refresh](https://reactnative.dev/docs/fast-refresh). +### 引入 -When you want to forcefully reload, for example to reset the state of your app, you can perform a full reload: +```tsx +import React, { useRef } from 'react'; +import MaskSegmentCanvas, { + type MaskSegmentCanvasRef, + type MaskSegmentSession, + type MaskSegmentWatchState, + type MaskSegmentWatchDetail, + type BgrColor, + type MaskSemanticColor, + type PaintCallbackPayload, + MASK_SEMANTIC_COLORS, + prewarmPngBgrCacheAsync, +} from 'react-native-mask-segment-canvas'; +``` -- **Android**: Press the R key twice or select **"Reload"** from the **Dev Menu**, accessed via Ctrl + M (Windows/Linux) or Cmd ⌘ + M (macOS). -- **iOS**: Press R in iOS Simulator. +也可按需导入运行时默认值（与组件 Props 合并使用）： -## Congratulations! :tada: +```tsx +import { + DEFAULT_PIPELINE_CONFIG, + DEFAULT_MASK_CONFIG, + DEFAULT_PAINT_CONFIG, + DEFAULT_INTERACTION_CONFIG, +} from 'react-native-mask-segment-canvas'; +``` -You've successfully run and modified your React Native App. :partying_face: +### 最小示例 -### Now what? +下面是一个可直接放进业务页面的完整示例，涵盖 **PNG 预热**、**state**、**配置**、**加载态**、**onWatch** 与 **ref** 常用操作。 -- If you want to add this new React Native code to an existing application, check out the [Integration guide](https://reactnative.dev/docs/integration-with-existing-apps). -- If you're curious to learn more about React Native, check out the [docs](https://reactnative.dev/docs/getting-started). +```tsx +import React, { useEffect, useRef, useState } from 'react'; +import { ActivityIndicator, Text, View } from 'react-native'; +import MaskSegmentCanvas, { + type MaskSegmentCanvasRef, + type MaskSegmentSession, + type MaskSegmentWatchState, + type BgrColor, + MASK_SEMANTIC_COLORS, + prewarmPngBgrCacheAsync, +} from 'react-native-mask-segment-canvas'; -# Troubleshooting +/** 业务侧准备好的图片地址（本地 file:// 或 http(s)://） */ +type ImagePaths = { + origin: string; + mask: string; +}; -If you're having issues getting the above steps to work, see the [Troubleshooting](https://reactnative.dev/docs/troubleshooting) page. +const INTERACTIVE_STATES: MaskSegmentWatchState[] = [ + 'interactive', + 'mask_paths_ready', +]; -# Learn More +export function PaintScreen() { + const canvasRef = useRef(null); -To learn more about React Native, take a look at the following resources: + const [imagePaths, setImagePaths] = useState(null); + const [pathsError, setPathsError] = useState(''); + const [watchState, setWatchState] = useState(''); + const [errorMessage, setErrorMessage] = useState(''); + const [sessionDraft] = useState(null); + + const isInteractive = INTERACTIVE_STATES.includes( + watchState as MaskSegmentWatchState, + ); + const isOutlineReady = watchState === 'mask_paths_ready'; + const isCanvasLoading = + imagePaths != null && + watchState !== '' && + !INTERACTIVE_STATES.includes(watchState as MaskSegmentWatchState) && + watchState !== 'error'; + + // 示例：接口下载完成后写入路径，并预热 PNG 解码缓存 + useEffect(() => { + let cancelled = false; + + (async () => { + try { + const origin = 'file:///path/to/origin.png'; + const mask = 'file:///path/to/mask.png'; + await prewarmPngBgrCacheAsync([origin, mask]); + if (!cancelled) { + setImagePaths({ origin, mask }); + } + } catch (e) { + if (!cancelled) { + setPathsError(e instanceof Error ? e.message : String(e)); + } + } + })(); + + return () => { + cancelled = true; + }; + }, []); + + const handleSave = async () => { + if (!isInteractive) return; + const result = await canvasRef.current?.save({ destDir: undefined }); + console.log('saved', result?.filePath, result?.paintedCount); + }; + + if (pathsError) { + return {pathsError}; + } + + if (!imagePaths) { + return ( + + + 等待原图与掩码… + + ); + } + + return ( + + {isCanvasLoading ? 加载中：{watchState} : null} + {watchState === 'interactive' ?
