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. 

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. 
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. 


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. 

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. 

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. 

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. 

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. 

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. 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
