A raster image conveys digital data. The bitmap consists of a grid of pixels. Each pixel specifies the colour and location of a point.
This format is capable of displaying intricate details. It is compatible with most web browsers. Such online images can be viewed on a screen, or printed out on paper.
Raster images are ideal for depicting complex realism, like photography and painting.
However, enlarging raster images poses challenges. The resulting pixelation leads to a blocky, jagged look.
Moreover, high-resolution raster files tend to be large, requiring substantial storage capacity.
