开发者您好，保存图片返回URI可参考以下示例：
//打开相册，获取图片,将URI转为pixeMap
async getImage():Promise<void> {
const photoSelectOptions = new picker.PhotoSelectOptions();
photoSelectOptions.MIMEType = picker.PhotoViewMIMETypes.IMAGE_TYPE; // 过滤选择媒体文件类型为IMAGE
photoSelectOptions.maxSelectNumber = LENGTH; // 选择媒体文件的最大数目
const photoViewPicker = new picker.PhotoViewPicker();
photoViewPicker.select(photoSelectOptions).then((photoSelectResult) => {
let URI = photoSelectResult.photoUris[0];
console.info(‘photoViewPicker.select to file succeed and URI is:’ + URI);
let file = fs.openSync(URI, fs.OpenMode.READ_ONLY);
const imageSourceApi = image.createImageSource(file.fd);
imageSourceApi.createPixelMap().then(pixelmap => {
console.log('Succeeded in creating pixelmap object ’ +
‘through image decoding parameters.’);
}).catch(error => {
console.log('Failed to create pixelmap object through image ’ +
‘decoding parameters.’);
})
}).catch((err) => {
console.error(Invoke photoViewPicker.select failed, code is ${err.code}, message is ${err.message});
})
}
