Media file picker features in .NET MAUI like in Xamarin Forms

Question

Hi,

Is there any way to compress the image and remove the metadata option for the media picker in MAUI like it had in the below package?

Hello,

You can select the photo from gallery by calling the MediaPicker.PickPhotoAsync() method and resize the image by calling Microsoft.Maui.Graphics.IImage API.

For more details, please refer to

Media picker for photos and videos - .NET MAUI | Microsoft Learn

Images - .NET MAUI | Microsoft Learn

and the following code:

private async void OnCounterClicked(object sender, EventArgs e)
{
     FileResult result = await MediaPicker.PickPhotoAsync();
 
     if (result != null)
     {
         var stream = await result.OpenReadAsync();
 
         ImageSource image = ImageSource.FromStream(() => stream);
         MyImage.Source = image; // display the image that didn't downsize
 
         var stream1 = await result.OpenReadAsync();
         var image1 = PlatformImage.FromStream(stream1);
         if (image1 != null)
         {
             var newImage = image1.Downsize(100, true);// downsize
             byte[] downsizeimage = newImage.AsBytes();
             var imageMemaryStream = new MemoryStream(downsizeimage);
             ImageSource source = ImageSource.FromStream(() => imageMemaryStream);
             ShowImage.Source = source;
 
         }
     }
}

Update

Is there any way to remove all the metadata from the image?

I got it. And I check the source code in MediaPlugin, this part is not included in MAUI. And there is a known issue reported on MAUI GitHub- Media Picker CameraOptions · Issue #23596 · dotnet/maui (github.com), please follow the progress.

Also, I understand that you want to remove the metadata on iOS and Android platform. The only way is to call the native iOS/ Android platform codes like the source code that I mentioned.
