CのMouseClickの画像をぼかして表示

Question

このフォームには画像ボックスがあります。その画像をクリックすると、カーソルのまわりの画像がぼやけてしまいます。何か案は？

画像全体をぼかすだけで別のPCで動作しましたが、私が追加したのはマウスの位置情報でしたし、何もしないようです。

public partial class Form1 : Form 
{ 
    Bitmap newBitmap; 
    Image file; 
    int blurAmount = 5 ; 
    public Form1() 
    { 
     InitializeComponent(); 
    } 

    private void button1_Click(object sender, EventArgs e) 
    { 
     DialogResult dr = openFileDialog1.ShowDialog(); 
     if (dr == DialogResult.OK) 
     { 
      file = Image.FromFile(openFileDialog1.FileName); 
      newBitmap = new Bitmap(openFileDialog1.FileName); 

      pictureBox1.Image=file; 
     } 

    } 

    private void Form1_MouseClick(object sender, MouseEventArgs e) 
    { 

     for (int x = e.Location.X-25; x < e.Location.X+25; x++) 
      { 
       for (int y =e.Location.Y-25; y < e.Location.Y+25; y++) 
       { 
        try 
        { 
         Color prevX = newBitmap.GetPixel(x - blurAmount, y); 
         Color nextX = newBitmap.GetPixel(x + blurAmount, y); 
         Color prevY = newBitmap.GetPixel(x, y - blurAmount); 
         Color nextY = newBitmap.GetPixel(x, y + blurAmount); 

         int avgR = (int)((prevX.R + nextX.R + prevY.R + nextY.R)/4); 
         int avgG = (int)((prevX.G + nextX.G + prevY.G + nextY.G)/4); 
         int avgB = (int)((prevX.B + nextX.B + prevY.B + nextY.B)/4); 

         newBitmap.SetPixel(x, y, Color.FromArgb(avgR, avgG, avgB)); 
        } 
        catch (Exception) {} 
       } 
      } 
      pictureBox1.Image = newBitmap; 
     } 
}

私はのPictureBoxのクリックイベントを設定し、細かい

public partial class Form1 : Form 
{ 
    Bitmap newBitmap; 
    Image file; 
    int blurAmount = 5; 
    public Form1() 
    { 
     InitializeComponent(); 
     // Occurs when the pictureBox1 control is clicked. 
     this.pictureBox1.Click += new System.EventHandler(this.pictureBox1_Click); 
    } 

    private void button1_Click(object sender, EventArgs e) 
    { 
     DialogResult dr = openFileDialog1.ShowDialog(); 
     if (dr == DialogResult.OK) 
     { 
      file = Image.FromFile(openFileDialog1.FileName); 
      newBitmap = new Bitmap(openFileDialog1.FileName); 

      pictureBox1.Image = file; 
     } 

    } 

    private void Form1_MouseClick(object sender, MouseEventArgs e) 
    { 

    } 

    private void pictureBox1_Click(object sender, EventArgs e) 
    { 
     MouseEventArgs me = (MouseEventArgs)e; 
     Point coordinates = me.Location; 

     for (int x = me.Location.X - 25; x < me.Location.X + 25; x++) 
     { 
      for (int y = me.Location.Y - 25; y < me.Location.Y + 25; y++) 
      { 
       try 
       { 
        Color prevX = newBitmap.GetPixel(x - blurAmount, y); 
        Color nextX = newBitmap.GetPixel(x + blurAmount, y); 
        Color prevY = newBitmap.GetPixel(x, y - blurAmount); 
        Color nextY = newBitmap.GetPixel(x, y + blurAmount); 

        int avgR = (int)((prevX.R + nextX.R + prevY.R + nextY.R)/4); 
        int avgG = (int)((prevX.G + nextX.G + prevY.G + nextY.G)/4); 
        int avgB = (int)((prevX.B + nextX.B + prevY.B + nextY.B)/4); 

        newBitmap.SetPixel(x, y, Color.FromArgb(avgR, avgG, avgB)); 
       } 
       catch (Exception) { } 
      } 
     } 
     pictureBox1.Image = newBitmap; 
    } 
}
