C# -用白色字节填充图像字节以填充512x512

using System;
using System.Drawing;

public class ImageProcessing
{
    public static void FillImageBytes(Bitmap image)
    {
        byte fillByte = 255; // 白色字节的值为255

        for (int y = 0; y < image.Height; y++)
        {
            for (int x = 0; x < image.Width; x++)
            {
                image.SetPixel(x, y, Color.FromArgb(fillByte, fillByte, fillByte));
            }
        }
    }

    public static void Main()
    {
        Bitmap image = new Bitmap(512, 512);
        FillImageBytes(image);
        image.Save("filled_image.png");
    }
