Lossless scaling is a method used to enlarge or scale back the dimensions of a picture with out dropping any of the unique information. That is in distinction to lossy scaling, which reduces the file measurement by eradicating a few of the information, leading to a decrease high quality picture. Lossless scaling is usually used for photographs that have to be enlarged for printing or different functions the place top quality is vital.
Lossless scaling is achieved through the use of algorithms that protect all the authentic information within the picture. This may be carried out through the use of a wide range of strategies, similar to bicubic interpolation or Lanczos resampling. These strategies work by creating new pixels which are interpolated from the unique pixels, making certain that the ensuing picture is as near the unique as doable.
