ImageFile.soften_mask

ImageFile.soften_mask()

Force the mask to soft (default), allowing unmasking by assignment.

Whether the mask of a masked array is hard or soft is determined by its ~ma.MaskedArray.hardmask property. soften_mask sets ~ma.MaskedArray.hardmask to False (and returns the modified self).
