A Dwizard.txt83 For example, to create a separate table for each of Y,Cb,Cr, you could
166 1 2; # Cb and Cr in second scan
171 # Interleaved DC scan for Y,Cb,Cr:
177 2: 1-63, 0, 0 ; # All AC coefficients for Cr
184 # Initial DC scan for Y,Cb,Cr (lowest bit not sent)
188 # Send all Cr,Cb AC coefficients, minus lowest bit:
190 # but note we send Cr first since eye is least sensitive to Cb)
