How to convert images to stream and byte array in the .NET MAUI Image Editor (SfImageEditor)?

The Syncfusion® .NET MAUI Image Editor provides functionality to convert images into a stream and then into a byte array. This demonstration explains how you can effectively achieve this conversion.

XAML:

Initialize the Image Editor control and handle the ImageSaving event.

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

You can get the image stream using the two methods below. Find the following code examples for better understanding.

Method 1:
In the ImageSaving event, use the ImageStream property to get the stream of the image.

C#:

private void OnImageSaving(object sender, ImageSavingEventArgs e)
{
   var stream = e.ImageStream;
   e.Cancel = true;
   var bytes = GetImageStreamAsBytes(stream);
}

Method 2:

In the ImageSaving event, use the GetImageStream method to get the stream of the image.

C#:

private async void OnImageSaving(object sender, ImageSavingEventArgs e)
{
   var stream = await imageEditor.GetImageStream(); 
   e.Cancel = true;
   var bytes = GetImageStreamAsBytes(stream);
}

The image stream can be converted to a bytearray using the stream retrieved from the ImageSaving event, as seen in the following code example:

C#:

private byte[] GetImageStreamAsBytes(Stream input)
{
   var buffer = new byte[16 * 1024];
   using (MemoryStream ms = new MemoryStream())
   {
       int read;
       while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
       {
           ms.Write(buffer, 0, read);
       }

       return ms.ToArray();
   }
}
