using var svgStream = new MemoryStream(svgBytes);

var svg = new SkiaSharp.Extended.Svg.SKSvg(new SKSize(500, 500));

svg.Load(svgStream);

using var bitmap = new SKBitmap(500, 500);
using var canvas = new SKCanvas(bitmap);

canvas.DrawPicture(svg.Picture);

using var outputStream = new FileStream("test.png", FileMode.Create);
using var image = SKImage.FromBitmap(bitmap);
using var data = image.Encode(SKEncodedImageFormat.Png, 100);

data.SaveTo(outputStream);
