Libtiff uses the names PHOTOMETRIC_MINISWHITE and PHOTOMETRIC_MINISBLACK. This implies something different than BlackIsZero. Does that help?

It's confusing. I usually use the names MinIsBlack and MinIsWhite... What's in a name?

Joris,

Craig Bruce referred to these as ZeroIsBlack which is quite distinct from MinIsBlack if you are thinking about signed integer values as he was.

Best regards,
