Hill shading: Bicubic interpolation by Sublimis · Pull Request #1548 · mapsforge/mapsforge
Yup, yes, nothing more regarding hill shading is planned in foreseeable future 👍 This last part was especially involving, but now hill shading bitmaps of theoretically any resolution and theoretically the best possible appearance (for the given data set) can be made by anyone by computing more bicubic points with the included method (double resolution algorithm is implemented in this PR).
