In computer graphics, graphics software or image editing software is a program or collection of programs that enable a person to manipulate visual images on a computer. These are the application software which lets the user to create and manipulate any type of computer graphics with the use of an operating system. Computer graphics can be classified into two distinct categories: raster graphics and vector graphics. Many graphics programs focus exclusively on either vector or raster graphics, but there are a few that combine them in interesting ways. 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 are animation and video editing software. The exact sources of graphics may vary for different tasks, but most can read and write files. Most graphics programs have the ability to import and export one or more graphics file formats, including those formats written for a particular computer graphics program. Examples of such programs include GIMP, Adobe Photoshop, Pizap, Microsoft Publisher, Picasa, etc. 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 an operating 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. == History == SuperPaint (1973) was one of the earliest graphics software applications. Fauve Matisse (later Macromedia xRes) was a pioneering program of the early 1990s, notably introducing layers in customer software.〔(Macromedia Matisse ), (Reign of Toads )〕 Currently Adobe 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. CorelDraw holds a stronger user base in Europe than Adobe. GIMP is a popular open source alternative to Adobe Photoshop. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Graphics software」の詳細全文を読む スポンサード リンク
