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. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall12 General-Purpose Applications

Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall13 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 Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall14 General-Purpose Applications

Portable Network Graphics (PNG) Patent-free alternative to a GIF Lossless compression, suitable for Web use only Windows Bitmap (BMP) Compression optional Files tend to be large Tag Image File Format (TIFF) Includes descriptive information with the image Used in publishing Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall15 General-Purpose Applications

Drawing programs create vector graphics that can be edited and resized without distortion. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall16 General-Purpose Applications
