To scan a document to convert an image into a form suitable for display on a computer monitor or printout. In telecommunications, hard copy documents are rasterized by a facsimile machine prior to transmission. In computing, documents are rasterized prior to electronic processing or storage.
To prepare a page for display or printing. Rasterization is performed by a raster image processor (RIP), which turns text and images into the matrix of pixels (bitmap) that will be displayed on screen or printed on the page. Various conversions may take place. For example, the mathematical coordinates of vector and outline fonts as well as vector drawings must be converted into bitmaps. Existing bitmaps may have to be scaled into different-sized bitmaps. Unless output is printed on a vector graphics plotter, which literally draws the illustration with pens, all text and graphics must be rasterized into a bitmap for display or printing. See RIP, raster scan, font scaler and host-based printer.
