Lossless scaling is a method used to enlarge or scale back the scale of a picture with out dropping any of the unique information. That is in distinction to lossy scaling, which reduces the file dimension by eradicating a number of the information, leading to a decrease high quality picture. Lossless scaling is usually used for photographs that must be enlarged for printing or different functions the place prime quality is vital.
Lossless scaling is achieved by utilizing algorithms that protect all the unique information within the picture. This may be executed by utilizing quite a lot of strategies, equivalent to bicubic interpolation or Lanczos resampling. These strategies work by creating new pixels which might be interpolated from the unique pixels, making certain that the ensuing picture is as near the unique as potential.
