What is rasterization?

Rasterization is the process of converting a vector graphic, which is made up of paths defined by mathematical expressions, into a raster image, consisting of pixels. In this transformation, the smooth edges and scalability of vector graphics are mapped into a fixed grid of colored pixels that can be displayed on a screen or printed on paper. This is essential in many graphic design applications, as raster images are widely used in web graphics, photographs, and other formats where detail and color depth are critical.

Understanding rasterization is important for graphic designers, as it impacts how images are used across different mediums, including print and digital. While the other options refer to different concepts in graphic design—such as printing methods, image enhancement, or types of software—they do not define rasterization itself. Rasterization specifically addresses the conversion process between vector and raster image formats, highlighting its significance in graphic design workflows.
