Rule Conditions
In routing rules, a condition is a comparison between a particular property of an image
and a user-supplied value. The results of the comparison determine if the rule will be
applied to an image or not.
A routing rule can contain multiple conditions. A single
when
statement precedes all
conditions in a rule.
