The code here is pretty straight forward. First create the blank image and get a Graphics object from it. Next, create the ColorMatrix that will convert the original image to grayscale. Declare an ImageAttributes object that will use the ColorMatrix and use it to draw the new image using DrawImage . Below is code for your proble m
