> {{org.apache.sis.image.Interpolation}} is currently an interface. There is some benefits to make it an abstract class instead. It would allow the addition of a package-private method for handling special cases that we do not want to expose in public API (those special cases are needed for resolving some exceptions observed with {{Visualization}}). Another potential (but not verified) benefit is a potential performance gain. The {{Interpolation.interpolate(…)}} method can be invoked million of times for each image, and benchmarks report [slightly faster method calls on abstract classes compared to interfaces|https://coderedirect.com/questions/200341/performance-difference-between-passing-interface-and-class-reloaded].
