    Description

      The org.apache.sis.image.Interpolation interface has predefined constants for NEAREST, BILINEAR and LANCSOZ, but currently no BICUBIC. Bicubic interpolation algorithm is described on Wikipedia. A first implementation attempt is done on on SIS feat/bicubic branch but is currently bugged. This branch should be debugged and more tests added before merge.

      Java Advanced Imaging (JAI) may be used as a reference implementation for checking the values. Attached is a class that may be used as a starting point, but also needs debugging.
