iOS/Android image picker with support for camera, video, configurable compression, multiple images and cropping
iOS/Android image picker with support for camera, video, configurable compression, multiple images and cropping
Import library
import ImagePicker from "react-native-image-crop-picker";
Call single image picker with cropping
ImagePicker.openPicker({ width: 300, height: 400, cropping: true, }).then((image) => { console.log(image); });
Call multiple image picker
ImagePicker.openPicker({ multiple: true, }).then((images) => { console.log(images); });
Select video only from gallery
ImagePicker.openPicker({ mediaType: "video", }).then((video) => { console.log(video); });
Android: The prop 'cropping' has been known to cause videos not to be displayed in the gallery on Android. Please do not set cropping to true when selecting videos.
ImagePicker.openCamera({ width: 300, height: 400, cropping: true, }).then((image) => { console.log(image); });
ImagePicker.openCamera({ mediaType: "video", }).then((image) => { console.log(image); });
ImagePicker.openCropper({ path: "my-file-path.jpg", width: 300, height: 400, }).then((image) => { console.log(image); });
Module is creating tmp images which are going to be cleaned up automatically somewhere in the future. If you want to force cleanup, you can use clean to clean all tmp files, or cleanSingle(path) to clean single tmp file.
ImagePicker.clean() .then(() => { console.log("removed all tmp images from tmp directory"); }) .catch((e) => { alert(e); });

| multiple | bool (default false) | Enable or disable multiple image selection |

| includeBase64 | bool (default false) | When set to true, the image file content will be available as a base64-encoded string in the data property. Hint: To use this string as an image source, use it like: <Image source={{uri: `data:${image.mime};base64,${image.data}`}} /> |
| includeExif | bool (default false) | Include image exif data in the response |
| avoidEmptySpaceAroundImage (ios only) | bool (default true) | When set to true, the image will always fill the mask space. |

On iOS, values larger than 0.8 don't produce a noticeable quality increase in most images, while a value of 0.8 will reduce the file size by about half or less compared to a value of 1. |

pod installIn Xcode open Info.plist and add string key NSPhotoLibraryUsageDescription with value that describes why you need access to user photos. More info here https://forums.developer.apple.com/thread/62229. Depending on what features you use, you also may need NSCameraUsageDescription and NSMicrophoneUsageDescription keys.
