Lossless scaling is a method used to enlarge or cut 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 dimension by eradicating a few of the information, leading to a decrease high quality picture. Lossless scaling is commonly used for photographs that should be enlarged for printing or different functions the place top quality is necessary.
Lossless scaling is achieved through the use of algorithms that protect all the unique information within the picture. This may be completed through the use of quite a lot of strategies, akin to bicubic interpolation or Lanczos resampling. These strategies work by creating new pixels which can be interpolated from the unique pixels, making certain that the ensuing picture is as near the unique as doable.
