AForge.NET Image Color Manipulation

I discovered AForge a few days ago with a goal in mind. I wanted to be able to manipulate an image's colors. However, after trying several different methods I have not been able to find a resolution. I looked thoroughly through the documentation they give, but it hasn't been any help to me. The specific part of the documentation I have been using is: http://www.aforgenet.com/framework/docs/html/3aaa490f-8dbe-f179-f64b-eedd0b9d34ac.htm

The example they give:

// create filter
YCbCrLinear filter = new YCbCrLinear( );
// configure the filter
filter.InCb = new Range( -0.276f, 0.163f );
filter.InCr = new Range( -0.202f, 0.500f );
// apply the filter
filter.ApplyInPlace( image );

I replicated it for a button click event, but the 'image' portion of it wasn't specified. I converted the image inside of my picturebox to a bitmap, then referenced it in the last line thinking that it would work. But it had no affect at all. My code is the following:

private void ColManButton_Click(object sender, EventArgs e)
{
Bitmap newimage = new Bitmap(pictureBox1.Image);
YCbCrLinear filter = new YCbCrLinear();
filter.InCb = new Range(-0.276f, 0.163f);
filter.InCr = new Range(-0.202f, 0.500f);
filter.ApplyInPlace(newimage);
}

My question essentially is, to anyone familiar or willing to help with this framework, how do I take my image and manipulate its color using AForge's YCbCrLinear Class under my button's click event?

Remember to set the picture box image after you have applied the filtering.

private void ColManButton_Click(object sender, EventArgs e)
{
    Bitmap newimage = new Bitmap(pictureBox1.Image);
    YCbCrLinear filter = new YCbCrLinear();
    filter.InCb = new Range(-0.276f, 0.163f);
    filter.InCr = new Range(-0.202f, 0.500f);
    filter.ApplyInPlace(newimage);

    pictureBox1.Image = newimage;
}
