Lossless scaling is a way used to enlarge or scale back the scale of a picture with out shedding any of the unique information. That is in distinction to lossy scaling, which reduces the file measurement by eradicating among the information, leading to a decrease high quality picture. Lossless scaling is usually used for pictures that have to be enlarged for printing or different functions the place top quality is vital.
Lossless scaling is achieved by utilizing algorithms that protect all the unique information within the picture. This may be accomplished by utilizing a wide range of strategies, comparable to bicubic interpolation or Lanczos resampling. These strategies work by creating new pixels which are interpolated from the unique pixels, guaranteeing that the ensuing picture is as near the unique as attainable.
