Bitmap vs. Jpeg — What's the Difference?

In computing, a bitmap is a mapping from some domain (for example, a range of integers) to bits. It is also called a bit array or bitmap index.

A standard algorithm for the compression of digital images.

A set of bits that represents a graphic image, with each bit or group of bits corresponding to a pixel in the image.

A digital image stored as a file so compressed

(computing) A series of bits that represents a rasterized graphic image, each pixel being represented as a group of bits.

Alternative case form of JPEG

An image represented as a two dimensional array of brightness values for pixels

A standardized format for storing graphic data in binary computer files, allowing over 16 million different colors. It allows for lossy compression, i. e. the compression of data into a form which re-expands into an image close, but not identical to the original image. Files stored in this format usually carry the extension jpg or jpeg. Compare GIF.
