Lossless scaling is a way used to enlarge or scale back the dimensions of a picture with out shedding 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 commonly used for pictures that should be enlarged for printing or different functions the place top quality is essential.
Lossless scaling is achieved by utilizing algorithms that protect all the authentic information within the picture. This may be finished by utilizing quite a lot of strategies, corresponding 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 potential.
