80 × 43 or 80 × 50, with an 8 × 8 font grid, with an effective resolution of 640 × 344 or 640 × 400 pixels. As with the pixel-based graphics modes, additional text modes are possible by programming the VGA correctly, with an overall maximum of about 100 × 80 cells and an active area spanning about 88 × 64 cells.
The fundamental strategy underlying the raster data model is the tessellation of a plane, into a two-dimensional array of squares, each called a cell or pixel (from "picture element"). In digital photography , the plane is the visual field as projected onto the image sensor ; in computer art , the plane is a virtual canvas; in geographic ...
The Multi-Color Graphics Array or MCGA is a video subsystem built into the motherboard of the IBM PS/2 Model 30, introduced in April 1987, and Model 25, introduced later in August 1987; no standalone MCGA cards were ever made.
The Extended Graphics Array (XGA) or originally Extended Video Graphics Array (Extended-VGA, EVGA) [119] is an IBM display standard introduced in 1990. Later it became the most common appellation of the 1024 × 768 [ 1 ] [ 75 ] [ 103 ] [ 84 ] pixels display resolution.
A GIF is an example of a graphics image file that uses a bitmap. [2] As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: the pix-map, which refers to a map of pixels, where each pixel may store more than two colors, thus using more than one bit per pixel. In such a case, the domain in question is the ...
Fixed pixel displays are display technologies such as LCD and plasma that use an unfluctuating matrix of pixels with a set number of pixels in each row and column. [ 1 ] [ 2 ] With such displays, adjusting ( scaling ) to different aspect ratios because of different input signals requires complex processing.
In computer graphics, the render output unit (ROP) or raster operations pipeline is a hardware component in modern graphics processing units (GPUs) and one of the final steps in the rendering process of modern graphics cards. The pixel pipelines take pixel (each pixel is a dimensionless point) and texel information and process it, via specific ...
The Thomson MO5 generated graphics based on a EFGJ03L (or MA4Q-1200) gate array [8] capable of 40×25 text display and a resolution of 320 x 200 pixels with 16 colours (subject to proximity constraints - only two colors for a 8x1 pixel area). [9]
