using Cairo; ... static void Main() { // Create a surface context var surface = new ImageSurface(Format.Argb32, 500, 500); var context = new Context(surface); // Draw a circle on the surface context context.Arc(250, 250, 100, 0, 2 * Math.PI); context.SetSourceRGB(1, 0, 0); context.Fill(); // Scale the surface context by a factor of 2 context.Scale(2, 2); // Draw another circle on the scaled surface context context.Arc(250, 250, 50, 0, 2 * Math.PI); context.SetSourceRGB(0, 0, 1); context.Fill(); // Save the surface context to a file surface.WriteToPng("scaled.png"); }In this example, we create a surface context and draw a red circle on it. Then, we call the Cairo Context Scale function to increase the size of the surface context. Finally, we draw a blue circle on the scaled surface context and save it to a PNG file. The Cairo graphics library is available as a NuGet package for use in C# projects.
