How to Save the Image in the Application Data Directory in the .NET MAUI Image Editor (SfImageEditor)

The Syncfusion® .NET MAUI Image Editor (SfImageEditor) allows you to save images directly to the application data directory. This guide demonstrates how to perform this task using the ImageSaving event.

XAML:

Initialize the Image Editor control and trigger the ImageSaving event.

<imageEditor:SfImageEditor x:Name="imageEditor" Source="image.png" ImageSaving="OnImageSaving">
</imageEditor:SfImageEditor>

C#:

In the ImageSaving event, use the Cancel property to restrict the default save location. Utilize the stream from the ImageSaving event to save the image in the application data directory.

private void OnImageSaving(object sender, ImageSavingEventArgs e)
{
   e.Cancel = true;
   var stream = e.ImageStream;
   var dataDirectory = FileSystem.Current.AppDataDirectory; // Use the application's data directory
   var fileFullPath = Path.Combine(dataDirectory, "SavedImage.png");
   SaveStreamToFile(fileFullPath, stream);
}

C#:

To write a stream to a particular file, create a FileStream object, then fill the bytes [] array with the stream data.

public void SaveStreamToFile(string fileFullPath, Stream stream)
{
   if (stream.Length == 0) return;
   // Create a FileStream object to write a stream to a file.
   using (FileStream fileStream = File.Create(fileFullPath, (int)stream.Length))
   {
       // Fill the bytes[] array with the stream data
       byte[] bytesInStream = new byte[stream.Length];
       stream.Read(bytesInStream, 0, bytesInStream.Length);
       // Use the FileStream object to write to the specified file.
       fileStream.Write(bytesInStream, 0, bytesInStream.Length);
   }
}
