using Pango; // create a layout Layout layout = new Layout(null); layout.SetText("Hello, world!"); // get pixel boundary Rectangle extents; layout.GetPixelExtents(out extents); // print the boundary Console.WriteLine("Left: " + extents.Left); Console.WriteLine("Right: " + extents.Right); Console.WriteLine("Top: " + extents.Top); Console.WriteLine("Bottom: " + extents.Bottom);This code creates a new layout and sets the text to "Hello, world!". The `out` parameter in `GetPixelExtents` is used to get the pixel boundary around the text. The results are printed on the console. The package library for Pango.Layout is "PangoSharp".
