Develop graphic for web and print product.

 In this unit we are going to see two separate modules.

1.Develop graphics for web or print media 

2.Design and develop static web page.

In this modules we are going to learn how we can edit modify digital image for printing purpose and how we can create a web page or web site 

Develop graphics for web or print media 

after completion of this module good will be able to perform fundamental operation on graphic application such as paint photo shop , coral draw. 

what is multimedia  

multimedia means interactive combination of two or more media element   ,such as text ,Graphics, Audio, Video and animation inter created using a computer.

Or

Multimedia is any combination of text ,Graphics, sound ,animation and video that is delivered by computer.

Desirable.

Computer Graphics
Computer graphic is a technology for presenting information any image that produced  by graphic computer application or computer graphic application or from simple image to complex, refers to any image to any computer device or programmed that makes a computer cables of displaying and manipulating image.

Why  Studying graphics ?
To make pretty pictures and funny movies. to improve understanding expiration and communication .
Graphic Application(software)
There are plenty of software are available for graphic development some of them are listed below.
1.Paint 
2.Illustration or design 
3.Presenttion graphics software.
4.Animation related software.
5.CAD software
6.Desktop publish
Graphic Categories
There are two main categories are available in graphics.
1.Vector graphics
    object base image represent by geometric form
2.Raster graphics
    The image represented by metrics picture
Raster VS vector 


Raster :-Photoshop , GIMP, Corel PaintShop Pro
Vector:- Adobe Illustrator, CorelDraw, and InkScape

Stranded format for graphic
BMP(Bitmap)
An old image format, image decompress, big in size, an accepted.
TIFF (Tagged image file format)
Image generated by scanner.
EPS(Encapsulated past script)
Image or illustation.
GIF(Graphic Interchange Format)
Stranded image for online interchange.
WMF.(Windows Metra file format)
using window operation system usually use for image vector clipart.
JPEG(Join Photography expert group)
suitable for photo picture not suitable for character.
 Image file format 
What is an file format?
Image file format are stranded way of organizing and starting of image file .Image file are composed  of either pictures or graphic data.
Image file size 
This is express as number of bits.
This value depend n two factors.
  • No f pictures on the screen.
  • Bite depth [Number of bits allocated of a pictures]
   Large No of rows and columns increase the the resolution and its leads to larger the file size.
Image file compression
Compression is a term use to describe ways of cutting the size of the file.
Why need image compression?
  1. Image file typically larger than the text file.
  2. Web pages often contain many images that are transmitted connection that can be slow.
  3. Image file can be quiet larger and the larger file means more disk usage and slower download.
  4. There for it is helpful in have a way to represent image in a compact format.
Type of image file compression.
There are two type of compression algorithms, there are.
  1. Listless compression
  2. Lossy compression.
Listless compression

Algorithms reduce file size without losing image Quality.
Through they are not compress in to as small a file as a lassie compression file.

Lossy compression.
This algorithms take advantage of the internet limitation of the human eye and discard invisible information.
Most lossy compression algorithms allow for variable quality levels[compression] and as these levels are increased
         File size is reduce.
          File types are belongs to the compression algorithms.
  1. Lossless compression → ROW, BMP, GIF, PNG
  2. Lossy compression→ 3PEG
Additive color

  Additive color synthesis is a creation of color by mixing color of light the additive or light theory deals with radiated and filtered light
        Red , Green , Blue.[RGB]



Subtractive color
Subtraction color synthesis is creation of color by mixing colors of pigment . such as paint or ink in our computer printers.
   Cyan, Magenta, Yellow,  black.[(MYK)] 



Color Theory
Color theory is a set of principles use to create harmonious color combination color relationship can be visually represented with a color wheel. the color spectrum wrapped on to a circle. 

1.A Primary color is a color that can not be made form a combination of any other color.
eg: Red , Yellow, Blue
   

2.A secondary color is a color create from combination pf two primary color.
eg: Orange, Purple, Green




3.Tertiary Color is a combination of three color (primary, Secondary)
eg: White, Black
