Create a new Bitmap object with the desired size, use Graphics.FromIm age
to create a graphics object for the bitmap, use the DrawImage method to
draw the original image onto the bitmap, then finally save the bitmap as
a file.

Tark,

You will want to create a new Bitmap class instance with the dimensions
that you want to resave the image to. Then, you will call the static
FromImage method on the Graphics class to get the Graphics instance for the
new image. Once you have that, you can call the DrawImage method on the
Graphics instance, passing the original image (and the new image
dimensions).
