What is meant by Image enlargement function?

The "Image Enlargement Function" is a feature in image editing software that allows enlarging the size of an image by increasing the number of pixels. This can be useful for magnifying details in an image or increasing the resolution of an image without significantly compromising quality. Typical functions of software in the "Image Enlargement Function" domain include:

Scaling algorithms: The software offers various algorithms for image scaling, which can provide different results depending on the user's requirements, including bilinear, bicubic, or Lanczos interpolation.
Interpolation options: The software allows the user to adjust the type of interpolation to achieve the best possible image quality, including options for Nearest-Neighbor, Bilinear, Bicubic, and Lanczos.
Customizable settings: The software provides the user with the ability to adjust various settings such as the desired enlargement factor, sharpness level, noise reduction, and other parameters to customize the result as needed.
Preview and comparison: The software allows the user to preview the enlarged version of the image and compare it with the original image to ensure that the result meets expectations.
Batch processing: The software offers the ability to enlarge multiple images simultaneously to optimize workflow and save time.
