How to change the image saving location in UWP?
2 mins read
By default, in SfImageEditor when we save image, the image will be getting saved in gallery. We can also able to change the image saving location.
Step 1: Create SfImageEditor sample with all necessary assemblies.
Please refer the below link to create a simple SfImageEditor sample along with the ways to configure it.

Step 2: Get stream from ImageSaving event. Create method for selecting folders and pass the stream as argument
Step 3: Convert the stream to bitmap and save image in custom location.
The following code snippet illustrates the way to this method,
C#
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
BitmapImage bitmapImage = new BitmapImage();
Uri uri = new Uri("ms-appx:///Assets/Image.jpg");
bitmapImage.UriSource = uri;
imageeditor.ImageSource = bitmapImage;
imageeditor.ImageSaving -= Imageeditor_ImageSaving;
imageeditor.ImageSaving += Imageeditor_ImageSaving;
}
Stream stream;
private void Imageeditor_ImageSaving(object sender, ImageSavingEventArgs args)
{
args.Cancel = true;
stream = args.Stream;
SelectDirectory(stream);
}
public async void SelectDirectory(Stream stream)
{
this.stream = stream;
IRandomAccessStream randomAccessStream = this.stream.AsRandomAccessStream();
var wbm = new WriteableBitmap(600, 800);
await wbm.SetSourceAsync(randomAccessStream);
string fileName = "image.jpg";
var folderPicker = new Windows.Storage.Pickers.FolderPicker();
folderPicker.SuggestedStartLocation =
Windows.Storage.Pickers.PickerLocationId.Desktop;
folderPicker.FileTypeFilter.Add("*");
Windows.Storage.StorageFolder folder = await folderPicker.PickSingleFolderAsync();
string SelectedFolderPath = folder.Path;
if (folder != null)
{
// Application now has read/write access to all contents in the picked folder
// (including other sub-folder contents)
Windows.Storage.AccessCache.StorageApplicationPermissions.
FutureAccessList.AddOrReplace("PickedFolderToken", folder);
StorageFile file = await folder.CreateFileAsync(fileName,
CreationCollisionOption.ReplaceExisting);
using (var storageStream = await file.OpenAsync(FileAccessMode.ReadWrite))
{
var encoder = await BitmapEncoder.CreateAsync(BitmapEncoder.JpegEncoderId, storageStream);
var pixelStream = wbm.PixelBuffer.AsStream();
var pixels = new byte[pixelStream.Length];
await pixelStream.ReadAsync(pixels, 0, pixels.Length);
encoder.SetPixelData(BitmapPixelFormat.Bgra8, BitmapAlphaMode.Ignore, (uint)wbm.PixelWidth, (uint)wbm.PixelHeight, 200, 200, pixels);
await encoder.FlushAsync();
}
}
}
}
