Functional Raster Image Processing in Scala
summary
A small Scala library models rasters as simple functions (a pure image type with width height apply), uses pixel type class abstractions, and composes lazy filters including a lanczos filter that filters before scaling to reduce aliasing. It claims simpler, more memory‑efficient pipelines and measurable speedups by avoiding unnecessary copies, but relies on java.awt with an Apache Imaging fallback and optional libturbojpeg native bindings, and currently suffers from a boxing/specialization bug that limits primitive performance; release planned MIT.
