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] Raster images are stored in image files with varying dissemination, production, generation, and acquisition formats. The printing and prepress industries know raster graphics as contones (from continuous tones).
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 shapes).
In computing, a bitmap (also called raster) graphic is an image formed from rows of different colored pixels. [1] A GIF is an example of a graphics image file that uses a bitmap. [ 2 ]
Raster-scan display sample; visible gaps between the horizontal scan lines divide each character. A raster scan, or raster scanning, is the rectangular pattern of image capture and reconstruction in television. By analogy, the term is used for raster graphics, the pattern of image storage and transmission used in most computer bitmap image systems.
Raster images can be created by a variety of input devices and techniques, such as digital cameras, scanners, coordinate-measuring machines, seismographic profiling, airborne radar, and more. They can also be synthesized from arbitrary non-image data, such as mathematical functions or three-dimensional geometric models; the latter being a major ...
