Bitmap
16 Dec, 2019 by
A bitmap is a data file representing a rectangular grid of pixels. It
defines a display space and color for each pixel (or “bit”) in the
display space. This type of image is known as a “raster graphic.” GIF’s
and JPEG’s are examples of image file types that contain bitmaps.
Because a bitmap uses this fixed raster method, it cannot easily be
rescaled without losing definition. Conversely, a vector graphic image
uses genome trial shapes to represent the image, and can thus be quickly
rescaled.
