IPA: /ˈræstər/
KK: /ˈræstər/
A pattern made up of closely spaced lines or dots that create an image on screens like televisions or computer monitors.
The image on the screen is created using a raster pattern of dots.
Raster → The word originates from Latin 'rastrum' (meaning a rake or scratcher), which refers to a tool used for gathering or smoothing soil. In modern usage, it describes a grid or pattern used in digital imaging, reflecting the original meaning of creating a structured layout.
Think of a 'rake' ('rastrum') that gathers and organizes things — that's why 'raster' refers to a structured grid in images.
