GRAPHICS PACKAGES

A graphics package is an application that can be used to create and manipulate images and graphics on a computer.

With graphic packages, several things can be created such as book cover, magazines, logos, posters, etc.

A Graphics package may not be as detailed as you think. It can be a simple paint package, which has features of shading, drawing line diagrams and many other simple but effective features.

As it is very difficult to draw with the mouse, many people scan the drawings on the computer and now there are software packages, which do not use a mouse.

There are two main types of graphics package:

  1. painting packages
  2. drawing packages

Types of Graphics Packages

Painting Packages:
  • A painting package produces images by changing the colour of pixels on the screen.
  • These are coded as a pattern of bits to create a bit-mapped graphics file.
  • Bitmapped graphics are used for images such as scanned photographs or pictures taken with a digital camera.
Advantage of Painting Packages
  • The main advantage offered by this type of graphic is that individual pixels can be changed which makes very detailed editing possible.
Disadvantages of Painting Packages
  • Individual parts of an image cannot be resized
  • Only the whole picture can be increased or decreased in size.
  • Information has to be stored about every pixel in an image which produces files that use large amounts of backing storage space.

Examples of graphics packages that produce bitmapped images include MS Paint, PC Paintbrush, Adobe Photoshop, etc.

 

Drawing Packages:
  • A drawing package produces images that are made up of coloured lines and shapes such as circles, squares and rectangles.
  • When an image is saved it is stored in a vector graphics file as a series of instructions, which can be used to recreate it.

Examples of drawing graphic packages include CorelDraw and Computer-Aided Design (CAD) packages such as AutoCAD, etc.
