| My comment: |

The technique of constructing a Graphics object based on an image works only for certain image formats. For example, you cannot construct a Graphics object based on an image that has a color depth of 4 bits per pixel.
GDI+ does not allow you to save an image to the same file that you used to construct the image. |
