我有一个移动应用程序，我希望用户拍照或从他们保存的相册中选择一个。
现在这两种功能都有效。问题出在保存的相册中。
为了防止压缩图像，我将allowEdit设置为true以基本上强制使用方形图片而不是矩形。使用相机拍摄照片时效果很好，但对保存的相册不起作用。
（查看网格线 - 裁剪工具）
是否有选项/解决方法来解决此问题？
（注意我在使用DATA_URL时知道常见的内存问题，但这是必需的）
/** takeImage - changes the image of a participant to a file from the camera */
changePicture(type: string) {
// processing might take a while, set up loading message
let loading = this.loadingCtrl.create({
content: 'Processing...',
spinner: 'crescent'
});
// set the phototype (make photo from camera or choose from gallery)
let photoType = Camera.PictureSourceType.CAMERA;
if(type === 'gallery') {
photoType = Camera.PictureSourceType.SAVEDPHOTOALBUM;
}
// setting up the options
Camera.getPicture({
quality: 85, // 85% to reduce size
destinationType: Camera.DestinationType.DATA_URL, // returns a base64 string
sourceType: photoType, // source type mentioned above
allowEdit: true, // allows us to crop the picture (force square) <-- doesnt work on SAVEDPHOTOALBUM
saveToPhotoAlbum: true, // saving the created photo to album (reusability)
correctOrientation: true, // allow the user to rotate the image
targetWidth: 200,
targetHeight: 200
}).then((imageData) => {
loading.present();
// change the image for every user
this.apiCaller.changeImage(this.participant.id, imageData).subscribe(response => {
// set the participant's base64image so it will be updated in the view
this.participant.base64image = imageData;
loading.dismiss();
});
}, err => {
alert(err);
});
}
