Masking
Channels in the
Compare Image
The channel masking function allows you to specify a bit, or bits in each
label that you do not want compared. This causes the corresponding bits in
all states to be ignored in the comparison. The compare data image itself
remains unchanged on the display. The Mask fields are directly above the
label and base fields at the top of both the Compare and Difference listings
(see figure 9-2). When you select one of these fields a pop-up appears in
whichyouspecifywhichchannelsaretobecomparedandwhichchannels
aretobemasked.A"." (period) indicates a don’t compare mask for that
channel and an "*" (asterisk) indicates that channel is to be compared.
