![]() ![]() One common implementation is to always round towards zero. 'Nearest' in nearest-neighbor doesn't have to be the mathematical nearest. This can preserve sharp details in pixel art, but also introduce jaggedness in previously smooth images. One of the simpler ways of increasing image size is nearest-neighbor interpolation, replacing every pixel with the nearest pixel in the output for upscaling this means multiple pixels of the same color will be present.
