Lossless scaling is a way used to enlarge or scale back the dimensions of a picture with out dropping any of the unique knowledge. That is in distinction to lossy scaling, which reduces the file measurement by eradicating among the knowledge, leading to a decrease high quality picture. Lossless scaling is commonly used for photos that must 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 knowledge within the picture. This may be executed by utilizing a wide range of strategies, equivalent 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.
