scanline
This term is primarily used in technical contexts involving display technology and computer graphics. It describes the physical or logical horizontal path of a beam or a data processing sequence. In the context of vintage CRT monitors, it refers to the actual visible lines on the screen, whereas in modern rendering, it refers to a conceptual unit of processing.
Because it describes a discrete, countable unit of a display or a rendering process, it follows standard English pluralization. It is rarely used outside of engineering, gaming, or digital art discussions, making it a highly specialized jargon term.
Meanings
A single horizontal row of pixels that is drawn or updated by an electron beam or a digital processor during the rendering of a video frame.
The old television screen showed a flickering scanline across the center of the image.
A specific line of data processed during a scanline rendering algorithm in computer graphics, where the image is generated one horizontal row at a time.
The renderer optimizes performance by calculating the visibility of objects for each scanline individually.
Examples
The old monitor has a visible scanline every few pixels.
I love the retro look of a scanline on these CRT screens.
The electron beam moves across each scanline from left to right.
Wait, is that a dead scanline or just a glitch in the signal?
The software calculates the color for every scanline in the frame.
A scanline rendering algorithm is often more efficient for simple 2D images.
The image flickers because the scanline refresh rate is too low.
He adjusted the settings to simulate a scanline effect for the game.
