Incomputer graphics,graphics software refers to aprogram or collection of programs that enable a person tomanipulate images or models visually on acomputer.[1]
Computer graphics can be classified into two distinct categories:raster graphics andvector graphics, with further 2D and3D variants. Many graphics programs focus exclusively on either vector or raster graphics, but there are a few that operate on both. It is simple to convert from vector graphics to raster graphics, but going the other way is harder. Some software attempts to do this.
In addition to static graphics, there areanimation andvideo editing software. Different types of software are often designed to edit different types of graphics such as video, photos, and vector-based drawings. The exact sources of graphics may vary for different tasks, but most can read and write files.[2]
Most graphics programs have the ability to import and export one or moregraphics file formats, including those formats written for a particular computer graphics program. Such programs include, but are not limited to:GIMP,Adobe Photoshop,CorelDRAW,Microsoft Publisher,Picasa, etc.[3]
The use of a swatch is a palette of active colours that are selected and rearranged by the preference of the user. A swatch may be used in a program or be part of the universal palette on anoperating system. It is used to change the colour of a text or image and in video editing. Vector graphics animation can be described as a series of mathematical transformations that are applied in sequence to one or more shapes in a scene. Raster graphics animation works in a similar fashion to film-based animation, where a series of still images produces the illusion of continuous movement.
SuperPaint was one of the earliest graphics software applications, first conceptualized in 1972 and achieving its first stable image in 1973[4]
Fauve Matisse (laterMacromedia xRes) was a pioneering program of the early 1990s, notably introducinglayers in customer software.[5]
CurrentlyAdobe Photoshop is one of the most used and best-known graphics programs in the Americas, having created more custom hardware solutions in the early 1990s, but was initially subject to various litigation.GIMP is a popular open-source alternative toAdobe Photoshop.
