Ive just recently started into using filter for computing, and have found a need for a logic function where bray is let through if the bray spectra matches the filter spectra exactly. Basically the Filter would test incoming bray for the same spectra it is set to. If it matches then the bray passes else it doesnt. Its a very small feature that would greatly increase the capability of filter computer logic, by essentially making IF THEN ELSE logic down to a single pixel.
