The following code example demonstrates how to use the FromFile GetPropertyItem and SetPropertyItem methods. This example is designed to be used with Windows Forms. To run this example, paste it into a form, and handle the form's Paint event by calling the DemonstratePropertyItem method, passing e as PaintEventArgs.
private void DemonstratePropertyItem(PaintEventArgs e) { // Create two images. Image image1 = Image.FromFile("c:\\FakePhoto1.jpg"); Image image2 = Image.FromFile("c:\\FakePhoto2.jpg"); // Get a PropertyItem from image1. PropertyItem propItem = image1.GetPropertyItem(20624); // Change the ID of the PropertyItem. propItem.Id = 20625; // Set the PropertyItem for image2. image2.SetPropertyItem(propItem); // Draw the image. e.Graphics.DrawImage(image2, 20.0F, 20.0F); }
