// Encode to PNG (lossless) using var data = bitmap.Encode(SKEncodedImageFormat.Png, 100); File.WriteAllBytes("skia_full_847.png", data.ToArray()); Console.WriteLine("✅ SkiaSharp image saved"); SkiaSharp automatically uses GPU acceleration when available, which can dramatically reduce the time required for rasterizing very large images. 5.5 Photoshop Scripting (ExtendScript) #target photoshop var W = 847; var H = 847;
