Instead, they rely on graphic software to rasterize images.

Convert (an image) into pixels
(Rasterizer) Rasterisation (or rasterization) is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (pixels or dots) for output on a video display or printer, or for storage in a bitmap file format.
(rasterized) Converted a projected point, line, or polygon, or the pixels of a bitmap or image, to fragments, each corresponding to a pixel in the framebuffer. Note that all primitives are rasterized, not just points, lines, and polygons.
(Rasterizer) A software program that converts font data for output as raster graphics, that is, into bitmaps. This step must be performed before characters can be displayed on the monitor or printed as a hardcopy. Unlike vector graphics, a raster graphic consists of pixels arranged in a fixed grid.
(rasterizer) The software component which interprets font data and renders text to the screen or printer.
(Rasterization) The process of converting mathematical and digital information (vector commands) into a series of dots by an output device.
(Rasterization) The process of turning polygons and other internally vector type graphics into raster graphics (made up of discrete pixels.)
(Rasterization) The creation of a 3D image.
(Rasterization) A way to convert the curves in type and illustrations (vector-based graphics) into a pattern of dots which can be displayed on a raster based screen or print device.
