Are they gone for good?
Can Ifind old version of the performance library with support for1bit pixels?
We canceled support of old performance libraries and we suggest to move to the new one instead. The IPP contains functions to convert to/from 1u data type, do you find this functionality useful for you purposes?
Yes, 1u8u conversions are definitely useful for me. But other 1u functions are gone.
You could still use the IPP logical image functions (and, or etc.) on images that are essentialy binary, even if the function thinks it is (e.g.) 8u.
it is not always as simple as logical image functions :-)
