Is there a good survey article on configuring lookup tables? We have an Adage with a 16 bit frame buffer. Let me explain the problem: The Adage can be expanded to full color mode i.e. with 24 bits of color. Just before the lookup tables, is a luvo switch which can be configured in one of two modes: full-color or pseudo-color. In full color the leftmost 8 bits is sent to the B lookup table, the middle 8 bits to the G lookup table and the rightmost 8 bits to the R lookup table. In pseudo color, 8 bits can be sent to R G and B tables simultaneously. I have been using the Adage mostly in this mode. Hence, with sixteen bits, one way to code the image is to have 7 bits of intensity and 9 bits of hue. How does one generate lookup tables for this? Any ideas and suggestions will be gratefully acknowledged. -- -------------- UUCP : {cmc12,hao,harpo}!seismo!rochester!rocksvax!sunybcs!krishnan ...{allegra,decvax,watmath}!sunybcs!krishnan CSNET : krishnan@buffalo ARPA : krishnan%buffalo@csnet-relay BITNET : krishnan@sunybcs --------------
