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 …

Mar 5, 2025 · 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.

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.

The two primary types of spatial data are vector and raster data in a GIS. But what is the difference between raster and vector data? When should we use raster and when should we use vector features? Find out more about the spatial data models commonly used.

Sep 18, 2024 · 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.

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.

Apr 12, 2021 · 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.

Jan 3, 2023 · Raster graphics are computer graphics that consist of a grid of pixels, also known as a bitmap. Most images on the Internet and your computer are raster graphics. They are one of the two primary image types for computer graphics with vector graphics. The file size of a raster graphic depends on several variables.
