Bitmap - English Definition & Meaning

Definition

A bitmap is a type of digital image composed of a grid of pixels, where each pixel is assigned a specific color. Unlike vector images, which are defined by mathematical equations, bitmaps store color information for each individual pixel. This makes them great for representing complex images with lots of detail, like photographs. However, scaling a bitmap image often results in pixelation, making it appear blurry or jagged. Think of it like a mosaic, where each tile (pixel) contributes to the overall picture 🖼️.

Etymology

The term 'bitmap' is a combination of 'bit' (binary digit, the smallest unit of data) and 'map' (a representation or arrangement). It directly reflects how the image is stored: as a map of bits, where each bit or group of bits corresponds to a pixel. The term originated in the early days of computer graphics and has been in use since the late 1960s.
