Yes, it is possible to add a watermark to saved or converted photos using Aspose.Imaging in .NET. Below is a sample code that demonstrates how to do this.

Sample Code to Add Watermark in .NET

using System;
using Aspose.Imaging;
using Aspose.Imaging.Brushes;

namespace Aspose.Imaging.Examples.CSharp.ModifyingAndConvertingImages
{
    public class AddWatermarkToImage
    {
        public static void Run()
        {
            Console.WriteLine("Running example AddWatermarkToImage");
            // Specify the path to the image file
            string dataDir = "path_to_your_image_directory/";
            
            // Load an existing image
            using (Image image = Image.Load(dataDir + "your_image.bmp"))
            {
                // Create an instance of Graphics class
                Graphics graphics = new Graphics(image);

                // Create a Font instance
                Font font = new Font("Times New Roman", 16, FontStyle.Bold);

                // Create a SolidBrush and set its properties
                SolidBrush brush = new SolidBrush();
                brush.Color = Color.Black;
                brush.Opacity = 100;

                // Draw the watermark text at a specific position
                graphics.DrawString("Your Watermark Text", font, brush, new PointF(image.Width / 2, image.Height / 2));
                
                // Save the image with the watermark
                image.Save(dataDir + "WatermarkedImage_out.bmp");
            }

            Console.WriteLine("Finished example AddWatermarkToImage");
        }
    }
}

Explanation

  1. Load the Image: The code loads an existing image from the specified directory.
  2. Create Graphics Object: A Graphics object is created to draw on the image.
  3. Define Font and Brush: A font and a solid brush are defined for the watermark text.
  4. Draw the Watermark: The watermark text is drawn at the center of the image.
  5. Save the Image: Finally, the modified image is saved with the watermark.

Make sure to replace "path_to_your_image_directory/" and "your_image.bmp" with the actual path and filename of your image.
