Recadrage polygonal d'images.

# react-native-expo-cropper

Un composant React Native basé sur Expo pour recadrer une image de manière polygonale à partir de la galerie ou de la caméra.

## 🔧 Installation

```bash
npm install react-native-expo-cropper

Ou

yarn add react-native-expo-cropper


EXPO SDK 54 -------------------------------------------------------------

"peerDependencies": {
    "expo": "54.0.0",
    "react": "19.1.0",
    "react-native": "0.81.4"
  },
  "dependencies": {
    "@expo/vector-icons": "^15.0.2",
    "expo": "^54.0.0",
    "expo-camera": "~17.0.8",
    "expo-image-manipulator": "~14.0.7",
    "expo-image-picker": "~17.0.8",
    "expo-media-library": "~18.2.0",
    "expo-screen-orientation": "~9.0.7",
    "react-native-svg": "15.12.1",
    "react-native-view-shot": "4.0.3"
  },


## ✅ IMPORTANT (APK / production build)

Expo Go already contains native camera modules/permissions. In a **standalone APK** you must ensure the native config is present.

Add this to your `app.json` / `app.config.js` (example):

```json
{
  "expo": {
    "plugins": ["expo-camera", "expo-image-picker", "expo-media-library"],
    "android": {
      "permissions": ["CAMERA"]
    }
  }
}
```

Then rebuild the APK (EAS / prebuild). If the camera crashes only in release, it’s almost always missing permissions/plugin config or a device-specific camera processing issue.

------------------------------ DO THIS IN YOUR APP SCREEN CODE !!!!!!!!!! :-------------------------------

import ImageCropper from 'react-native-expo-cropper/src/ImageCropper';


  const [crop, setCrop] = useState(false);
  const [useCameraInCropper, setUseCameraInCropper] = useState(false);
  const [initialImageForCropper, setInitialImageForCropper] = useState(null);




 TO OPEN THE GALERIE BEFORE THE CROPPER YOU NEED TO ADD THIS IN YOU APP SCREEN CODE TOO :
 
 const handlePickAndCropImage = async () => {
  try {
    const result = await ImagePicker.launchImageLibraryAsync({
      mediaTypes: ImagePicker.MediaTypeOptions.Images,
      allowsEditing: false,
      quality: 1,
    });

    if (!result.canceled && result.assets.length > 0) {
      setInitialImageForCropper(result.assets[0].uri);
      setUseCameraInCropper(false); // sécurité
      setCrop(true);
    }
  } catch (error) {
    console.log("Erreur lors du choix de l'image :", error);
  }
}; 




YOUR CAMERA AND GALERY Bottons :


        <TouchableOpacity
              style={styles.buttonOutline}
              onPress={() => {
                setUseCameraInCropper(true);
                setCrop(true);
              }}
            >
              <Text style={styles.buttonTextB}>Take A photo</Text>
            </TouchableOpacity>

            <TouchableOpacity
              style={styles.buttonOutline}
              onPress={handlePickAndCropImage}
            >
              <Text style={styles.buttonTextB}>Chose image From the phone Galerie</Text>
            </TouchableOpacity>




condition:

{crop ? (
  <View style={{ flex: 1 }}>
    <TouchableOpacity
      onPress={() => {
        setCrop(false);
        setUseCameraInCropper(false);
      }}
      style={{
        position: 'absolute',
        top: 40,
        right: 5,
        zIndex: 9999,
        backgroundColor: '#ffffffaa',
        padding: 10,
        borderRadius: 3,
      }}
    >
      <Text style={{ fontSize: 20, fontWeight: 'bold' }}> X </Text>
    </TouchableOpacity>

    <ImageCropper
        initialImage={initialImageForCropper}
        openCameraFirst={useCameraInCropper}
        onConfirm={(uri, name) => {
          setImage(uri);
          setURi(uri);
          setImageName(name);
          setCrop(false);
          setUseCameraInCropper(false);
          setInitialImageForCropper(null);
          setIsReady(true);
        }}
        onCancel={() => {
          setCrop(false);
          setUseCameraInCropper(false);
          setInitialImageForCropper(null);
        }}
      />

  </View>
