How do I transfer an image from my app to the local machine?

Question

Hi there,

I'm making an app that includes an image as it's background and I was wondering if there is a way to transfer that image to the image folders on the user's computer.

So if we say that the uri for the image is 'ms-appx:///backgrounds/1.jpg', how would I make a copy of that image into the pictures library?

Thanks!

Answer 1

open the file with the uri you have with ;

StorageFile.getFileFromApplicationUriAsync

then copy the file with :

StorageFile.copyAsync

and as location you set KnownFolders.picturesLibrary.

I don't have visual studio here otherwise would have given a working sample. but my js isn't fluent enough to do without testing

I came up with this but the app just crashes when I call the function. What am I doing wrong? Seems to fall over when getting the folder.

function SaveBackground() {
    var uri = new Windows.Foundation.Uri("ms-appx:///backgrounds/1.jpg")
    Windows.Storage.StorageFile.getFileFromApplicationUriAsync(uri).done(function (file) {
        var destiationFolder = Windows.Storage.KnownFolders.savedPictures;
        var desiredName = "background.jpg";
        var option = Windows.Storage.NameCollisionOption.generateUniqueName;

        file.copyAsync(Windows.Storage.KnownFolders.savedPictures, desiredNewName, option).done( /* Your success and error handlers */);
    });
}

Answer 3

code looks good. did you enable PictureLibrary access in the manifest file?

I don't get any exception, the app just crashes and debugging ends. It still seems to stem from the folder.
