Raster graphic image In computer graphics , rasterisation ( British English ) or rasterization ( American English ) is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (a series of pixels , dots or lines, which, when displayed together, create the image which was represented via ...
The input to vectorization is an image, but an image may come in many forms such as a photograph, a drawing on paper, or one of several raster file formats. Programs that do raster-to-vector conversion may accept bitmap formats such as TIFF, BMP and PNG. The output is a vector file format. Common vector formats are SVG, DXF, EPS, EMF and AI.
In computer graphics and digital photography, a raster graphic represents a two-dimensional picture as a rectangular matrix or grid of pixels, viewable via a computer display, paper, or other display medium. A raster image is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. [1]
For example, in the Chauvet-Pont-d'Arc Cave (circa 30,000 BC), at least 13 different species have been identified. [2] In one prehistoric cave (circa 15,000 BC), there is a drawing of a mammoth with a darkened area where the heart should be. If this is indeed the intention of the illustration, it would be the world's first anatomical ...

Digital illustrations may include both raster and vector graphics in the same work. A bitmap image file may be saved in a format which embeds a layer of vector information, and vector image file may include imported bitmap images. Example of a digital illustration made on a mobile phone and personification art.
Prostista taxonomy vs. phylogeny - This diagram shows the phylogeny of eukaryotes based on some recent analyses superimposed over the current kingdom and subkingdom-level taxonomy of protists. The purpose of the image is to demonstrate the paraphyly of most protist groupings, particularly those belonging to kingdom Protozoa: subkingdom Eozoa.
