one function returns you pointer to a Dib, the other returns you a filename.
And it doesn’t seem to me that saving to disk is _always_ the case. It seems entirely likely that there are situations where you only need to view the image, not save it to disk. Then it seems that there may also be cases when you want to manipulate the image before you save it to disk – just use the appropriate function for your case.
