General-Purpose Applications
Codecs are algorithms that reduce file size and allow faster Internet transfer speeds. Lossless compression does not delete
any information needed to reproduce the image without flaw.
Lossy compression removes some information, but the loss is typically not noticeable.

General-Purpose Applications
Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall 13
Use paint programs to create bitmapped images (raster graphics), which are made up of tiny dots known as pixels.
General-Purpose Applications
Paint program standard file formats Graphics Interchange Format (GIF)
Lossless compression of simple images Often used for Web pages
Joint Photographic Experts Group (JPEG)
Lossy compression of complex images Also used for Web pages
