If the goal is maximal performances, the current code is likely better. The use of `Rectangle.intersection(Rectangle)` was proposed for safety rather than performance, because `Rectangle` is robust to integer underflow and overflow. However, I think that the current `WritableRaster.setRect(Raster)` code can underflow/overflow only if the checks performed at `Raster` construction time were bypassed, for example by modifying the protected fields after construction. ------------- PR Comment: https://git.openjdk.org/jdk/pull/13797#issuecomment-1804395307
