Definition: The process of converting a vector image into a bitmap image. (Continued below...)

When you open a vector image in a bitmap-based editing program, you are usually presented with a dialog box of options for rasterizing the image. These options are where you would specify the pixel dimensions, color mode, and resolution of the imported file (see below). A vector graphic can also be rasterized by exporting it from a vector-based application to a bitmap format. Anti-aliasing and dithering are also options that may be offered when rasterizing an image.

This is the rasterize dialog box you will see when importing a vector-based image into Photoshop.
