To convert vector graphics to raster or bitmapped graphics.

process of converting a vector image to a bitmap (a raster-based or pixelbased image)

raster display is one that is made up of a grid of pixels (contrast this with now-extinct vector displays which displayed graphics by tracing them like a pen -- think Asteroids). Rasterization is frequently used in the context of converting vector-based graphics (e.g. Illustrator, PostScript files) into pixel-based graphics (e.g. TIFF's, GIF's). Effective rasterization relies on antialiasing.

The conversion of an object-oriented image into a bitmapped image. When an Adobe Illustrator graphic is placed or opened in PhotoShop, it is rasterized. All computer files are rasterized when they're printed.

The process of converting vector points, lines and areas into raster image format.

to transform a graphical image into a bitmap so that it fits the shape and size of a raster output device such as a printer.
