Image scaling is the process of resizing an image to make it larger or smaller while maintaining its quality. This technique is commonly used in digital graphics, photography, and web design to ensure that images fit well within different formats or screen sizes. There are two main types of image scaling: upscaling and downscaling. Upscaling increases the dimensions of an image, which can sometimes lead to a loss of clarity, while downscaling reduces the size, often preserving quality. Various algorithms, such as bilinear and bicubic, are used to achieve the best results during this process.
