Work with bitmaps faster in C#

I got what A.J tried to say. It's about implementing IDisposable in LockBitmap. Basically, it involves changing:

public class LockBitmap

to:

public class LockBitmap : IDisposable

The constructor:

public LockBitmap(Bitmap source)
{
    this.source = source;
}

to:

public LockBitmap(Bitmap source)
{
    this.source = source;
    LockBits();
}

and create a new method:

public void Dispose()
{
   UnlockBits();
}

So, the class usage will change from this

LockBitmap lockBitmap = new LockBitmap(bmp);
lockBitmap.LockBits();
(...)
lockBitmap.UnlockBits();

to this

using(LockBitmap lockBitmap = new LockBitmap(bmp))
{
    (...)
}

more elegant, IMO.
