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.

Get to know the two main image file types — raster and vector. Learn about the main features and differences between raster and vector to make sure you use the right one.

The meaning of RASTER is a scan pattern (as of the electron beam in a cathode-ray tube) in which an area is scanned from side to side in lines from top to bottom; also : a pattern of closely spaced rows of dots that form an image (as on the cathode-ray …

2025年3月5日 · Raster graphics are a type of digital image that uses tiny rectangular pixels arranged in a grid formation to represent an image. Images produced from optical scanners and digital cameras are raster graphics, as are most images on the Internet.

2024年9月18日 · Discover what raster graphics are, how they differ from vector images, and why they're essential for digital imaging. Learn about pixel-based images used in digital photography and web graphics, and explore their applications and limitations.

In its simplest form, a raster consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature. Rasters are digital aerial photographs, imagery from satellites, digital pictures, or even scanned maps.

Raster may refer to: Raster graphics, graphical techniques using arrays of pixel values; Raster graphics editor, a computer program; Raster scan, the pattern of image readout, transmission, storage, and reconstruction in television and computer images; Rasterisation, or rasterization, conversion of a vector image to a raster 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).

One of the strengths of raster files is the ability to capture detailed graphics and high-quality photographs taken from digital cameras. Explore the key features of raster images, their most common uses, and how they differ from vector images.

2021年4月12日 · Raster is lines on the inside of the screen traced by an electron beam to create an image called a horizontal scan line. These lines appear on a CRT (Cathode Ray Tube) monitor or a TV screen.
