Which of the following would NOT be considered an enhancement for bitmapped images?

Vectorization is the process of converting bitmap images, which consist of pixels, into vector images made up of paths defined by mathematical expressions. This technique is fundamentally different from the enhancements typically applied to bitmapped images, which are primarily focused on manipulating the pixel data directly to improve or alter the imagery without changing its fundamental structure.

In contrast, enhancements like filters, anti-aliasing, and effects involve adjustments or modifications that are applied to the pixel data of a bitmap image. Filters can alter the color, brightness, or contrast of an image, while anti-aliasing smooths out jagged edges, making them appear less pixelated. Effects can encompass a wide range of modifications, such as adding blurs, shadows, or textures. Each of these enhancements aims to improve the appearance of the existing pixel-based image rather than transforming it into a different format altogether. Therefore, vectorization stands apart as it represents a fundamental change in the image type, rather than an enhancement to an existing bitmap.
