  • private void button1_Click(object sender, EventArgs e)
    {
    //以浮雕效果显示图像
    
    int Height = this.pictureBox1.Image.Height;
    int Width = this.pictureBox1.Image.Width;
    Bitmap newBitmap = new Bitmap(Width, Height);
    Bitmap oldBitmap = (Bitmap)this.pictureBox1.Image;
    Color pixel1, pixel2;
    for (int x = 0; x < Width - 1; x++)
    {
    for (int y = 0; y < Height - 1; y++)
    {
    int r = 0, g = 0, b = 0;
    pixel1 = oldBitmap.GetPixel(x, y);
    pixel2 = oldBitmap.GetPixel(x + 1, y + 1);
    r = Math.Abs(pixel1.R - pixel2.R + 128);
    g = Math.Abs(pixel1.G - pixel2.G + 128);
    b = Math.Abs(pixel1.B - pixel2.B + 128);
    if (r > 255)
    r = 255;
    if (r < 0)
    r = 0;
    if (g > 255)
    g = 255;
    if (g < 0)
    g = 0;
    if (b > 255)
    b = 255;
    if (b < 0)
    b = 0;
    newBitmap.SetPixel(x, y, Color.FromArgb(r, g, b));
    }
    }
    this.pictureBox1.Image = newBitmap;
