     创建一张500*500的高度图PNG图片

        public static void GenerateHeightMapPNG(){Image image = new Image();image.Width = 500;image.Height = 500;image.Comp = 4;image.Data = new byte[image.Width * image.Height * image.Comp];for (int y = 0; y < image.Height; y++){for (int x = 0; x < image.Width; x++){int index = (y * image.Width + x) * image.Comp;if (x > 250 && y > 250){image.Data[index] = 255;image.Data[index + 1] = 0;image.Data[index + 2] = 0;image.Data[index + 3] = 255;}else{image.Data[index] = 255;image.Data[index + 1] = 255;image.Data[index + 2] = 255;image.Data[index + 3] = 255;}}}FileInfo fileInfo = new FileInfo("test.png");if (!fileInfo.Exists){fileInfo.Create();}ImageWriter imageWriter = new ImageWriter();imageWriter.WritePng(image, fileInfo.OpenWrite());}
