Computer graphics are graphics
created using computers
and, more generally, the representation and manipulation of image data by a computer
with help from specialized software
and hardware.
Typically,
the term computer graphics refers to several different things:
- The representation and manipulation of image
data by a computer
- The various technologies
used to create and manipulate images
- The sub-field of computer
science which studies methods for digitally synthesizing and
manipulating visual content.
- Developments in computer graphics have had a
profound impact on many types of media and have revolutionized animation, movies and the video game industry.
- Computer generated imagery can be categorized
into several different types: 2D, 3D, and animated graphics.
- As technology has improved, 3D computer
graphics have become more common, but 2D computer graphics are still
widely used.
Computer
graphics may be used in the following areas:
computer graphics software
- GIMP
- Corel
Draw
- Photoshop
GIMP (GNU Image Manipulation Program)
GIMP (GNU Image Manipulation Program) is an image retouching and editing tool and free and open-source software. There are
versions tailored for most operating systems including Microsoft Windows,
Mac OS X
and Linux.
GIMP
has tools used for image retouching and editing, free-form drawing, resizing,
cropping, converting between different image formats, and more specialized
tasks. Animated images such as GIF and MPEG files can be created using an
animation plugin.
The
developers and maintainers of GIMP strive to be a high-end free software
graphics application for the editing and creation of original images, photos,
icons, graphical elements of web pages and art for user interface elements.
Teachers can make use of the Gimp in three main
areas: (Educational Use of GIMP)
1) A free and relatively
easy to use tool to edit images that you may use when building presentations,
handouts, worksheets, tests, web content, or any other digital or print media.

at school.
2) A free tool that will
work on any platform (windows, Mac OS,
Linux) including older machines that you can use to teach students concepts of
digital photography, image editing, or as a tool for students to edit images
used in their own reports and presentations.

analysis of digital images taken for scientific purposes. It is possible to
strip out certain color bands, adjust brightness and contrast, take
measurements, and form conclusions based upon image data.
