bitmap
Dot-matrix image
A bitmap is an image stored as a grid of individual pixels, each with its own color value.
The term contrasts with vector graphics, which store images as mathematical shapes.
Bitmap formats like JPEG, PNG, and BMP lose quality when scaled up because enlarging reveals the pixel grid.
As a verb, to bitmap is to convert an image to this format.
