I would like to make the figures on the images (which are currently semi-transparent) be totally opaque, and go from the greyish color they are to being totally white (#ffffff). How would I go about this using convert? All of the images also have these different amounts of alpha on the figures, so I can't do a blind one-color-for-another replace.
