using System.Drawing; using System.Runtime.InteropServices; //get a device context for the window IntPtr hdc = GetDC(IntPtr.Zero); //load the bitmap image Bitmap image = new Bitmap("image.bmp"); //create a rectangle object to define the position and size of the image Rectangle rect = new Rectangle(0, 0, image.Width, image.Height); //draw the image onto the device context DeviceContext dc = DeviceContext.FromHdc(hdc); dc.DrawBitmap(image, rect, rect, 255); dc.Dispose(); //release the device context ReleaseDC(IntPtr.Zero, hdc);In this example, we are loading an image file and drawing it onto the screen using DeviceContext.DrawBitmap. We first get a device context for the window, then load the bitmap image and create a rectangle object to define its position and size. Finally, we draw the image onto the device context and release it. The package library used for this example is likely System.Drawing, which provides classes and methods for working with graphics in .NET.
