How to change pen annotation default color in the .NET MAUI Image Editor?

In the Syncfusion® .NET MAUI ImageEditor control, you can customize the default color of the pen annotation.

Initialize the SfImageEditor control, provide the source image through the Source property, and trigger the AnnotationSelected event.

XAML:

<imageEditor:SfImageEditor x:Name="imageEditor" 
                          Source="image.png" 
                          AnnotationSelected="OnAnnotationSelected">
</imageEditor:SfImageEditor>

In the OnAnnotationSelected event, you can modify the default color of the pen with the help of the Color property in the ImageEditorShapeSettings. Refer to the below code sample for better understanding.

C#:

private void OnAnnotationSelected(object sender, AnnotationSelectedEventArgs e)
{
   if (e.AnnotationSettings is ImageEditorShapeSettings shapeSettings)
   {
       shapeSettings.Color = Colors.CadetBlue;
   }
}
