whenever I Retrieved Image from the database it is not showing full image into the picturebox in c sharp

        int PicBoxHeight = 0;
	int PicBoxWidth = 0;
	int ImageHeight = 0;
	int ImageWidth = 0;
	Image TempImage = default(Image);
	float scale_factor = 0;
	PictureBox1.SizeMode = PictureBoxSizeMode.Normal;
	// Get control size
	PicBoxHeight = PictureBox1.Height;
	PicBoxWidth = PictureBox1.Width;
// Load the image. Change Image.FromFile() to match your code
	TempImage = Image.FromFile("D:\\Download\\Image00b.jpg");
	// Get image size
	ImageHeight = TempImage.Height;
	ImageWidth = TempImage.Width;
	// Calculate scale_factor
	scale_factor = 1.0;
	// No scaling by default i.e. image fits in the Box
	// 1) Height
	if (ImageHeight > PicBoxHeight) {
		// Reduce height first
		scale_factor = Convert.ToSingle(PicBoxHeight / ImageHeight);
	}
	// 2) Width. Notice, we do know now how much we have to scale down the height
	// and the scale_factor affects width too
	if ((ImageWidth * scale_factor) > PicBoxWidth) {
		// Scaled width exceeds Box's width, recalculate scale_factor
		scale_factor = Convert.ToSingle(PicBoxWidth / ImageWidth);
	}
	// Move image to control for resizing
	PictureBox1.Image = TempImage;
	// Get the source bitmap.
	Bitmap bm_source = new Bitmap(PictureBox1.Image);
	// Make a bitmap for the result.
	Bitmap bm_dest = new Bitmap(Convert.ToInt32(bm_source.Width * scale_factor), Convert.ToInt32(bm_source.Height * scale_factor));
	// Make a Graphics object for the result Bitmap.
	Graphics gr_dest = Graphics.FromImage(bm_dest);
	// Copy the source image into the destination bitmap.
	gr_dest.DrawImage(bm_source, 0, 0, bm_dest.Width + 1, bm_dest.Height + 1);
	// Display the result.
	PictureBox1.Image = bm_dest;
