The normal action of "-monochrome" is to simply do "-type bilevel". This has the result of forcing images to be pure black and white. However it also has a weird side-effect I recently discovered while reviewing the CLI API interface in that it sets a flag that effects PDF image reading, forcing it to get a monochrome image from the ghostscript interface. It seems a little strange to me, and I would have thought doing a "-type bilevel" would do the same thing, but evidentially that is not the case, and I am not certain why! I have flagged the option for further review, perhaps make it exactly equivalent to "-type bilevel", which is both a setting and a operator.
