  1. 1.   Tagged Image File Format Computer file format for storing raster graphics images    Advantages of using this file type: No loss of image data Free exchange between applications and computer platforms
  2. 2.   Joint Photographic Expert Group  Method of lossy compression for digital photography   Retains up to 16,000,000 colors Ability to compress more or less to find a compromise between file format and image quality Main advantage of the display of continuous tone images such as photographs on the Web or other online services
  3. 3.  Graphics Interchange Format    Describes a fixed-sized graphical area populated with zero or more "images".  Easy to store and display Can be made into a transparent image Main uses are for displaying images in greyscale, transparent images where color variation is unimportant but where small file sizes are desirable.
  4. 4.    Portable Network Graphics Raster graphics file format that supports lossless data compression Supports palette-based images, grayscale images, and full-color non-palettebased RGB[A] images  Preserves alpha channels and full colour range.  Lossless file preservation.  Main use for a web page  Preservation of channels for masks and/or printing.
  5. 5.   Motion Picture Experts Group High quality video format used for Internet files    Algorithms compress data to form small bits that can be easily transmitted and then decompressed MPEG1: Used for VCD MPEG2: Used for DVD
  6. 6.   AKA bitmap image file, or device independent bitmap (DIB) file format A set of bits that represents a graphic image, with each bit or group of bits corresponding to a pixel in the image  Capable of storing 2D digital images of arbitrary width, height, and resolution, both monochrome and color, in various color depths and optionally with data compression, alpha channels, and color profiles
  7. 7.   Collection of unprocessed data Sometimes called digital negatives, as they fulfill the same role as negatives in film photography    Often used as data files by software programs that load and process the data Used by high-end and professional digital cameras Can be edited by Adobe Photoshop
  8. 8.   Portable Arbitrary Map  Data that is arranged as a two dimensional rectangular array, or even a three dimensional array  Defines attributes such as height, width, and maximum value and also depth and tuple type A convenient way to read and write the PAM format accurately is via the libnetpbm C subroutine library
  9. 9.   Vector Graphics The use of geometrical primitives such as points, lines, curves, and shapes or polygons which are all based on mathematical expressions to represent images in computer graphics   Raster Graphics A dot matrix data structure representing a generally rectangular grid of pixels or points of color, viewable via a monitor, paper, or other display medium
  10. 10. Vector Graphics are basically composed of paths or lines that are either straight or curved while Raster Graphics are basically composed of pixels of various colors, which together form an image
