Thanks, I've been working very closely with the spec but haven't noticed this BlackIs1 parameter, but I did figure out that I could use the decode parameter to fix it.

Is there some property that you know of to set in the PDF for showing that this field is reversed?

Try to set the /BlackIs1 parameter, or use /Decode [1 0]. In my experience, the /CCITTFaxDecode filter exactly reverses the meaning of those parameters, despite what the PDF spec says. For the rest, the PDF spec is very enlightening; practically all flags you can find in a TIFF can be set in the PDF as well, also for the other compression methods. You can find the spec at http://partners.adobe.com/asn/developer/technotes.html or thereabout.
