Abstract
Some devices, systems, and methods calculate a transition region periodicity as a least a common multiple of a first periodicity of a first uniform-feature segment and a second periodicity of a second uniform-feature segment; determine a plurality of periodic elements of the transition region based on the transition region periodicity; determine a number of drops for each periodic element of the plurality of periodic elements of the transition region based on a volume requirement of the periodic element; and select, for each periodic element of the plurality of periodic elements of the transition region, a transition-region drop pattern that has the number of drops and that minimizes a metric that is a weighted sum of inverse distances between drops in the periodic element and drops in the first uniform-feature segment and the second uniform-feature segment that are adjacent to the periodic element.
