This window contains a number of rules stacked in a vertical tab arrangement. Each rule has a corresponding stretch that is applied should the rule match.
When a new file is opened, these rules are evaluated in order (Rule 1 first, then Rule 2 and so on). The first rule that matches is chosen and the stretch defined used to open the file.
When Viewer is first opened a default set of stretches is created.
Note that changes to the default stretch are only saved with the user clicks 'OK'. Changes can be discarded by clicking 'Cancel'.
Each rule contains the following items:
The number of bands relationship combo
You can define whether you want this rule to match images with a number of bands equal to, less than or greater than the number on the right.
Color table in band rule
You can make this rule match images with a color table in a specific band by changing the value on the right from 'Color Table not Required' to a valid band number.
The details of the stretch are documented in the Stretch Window.
