1. 欢迎使用 GIMP

GIMP是一个多平台工具,用于创建和编辑各种图像。GIMPGNU Image Manipulation Program的首字母缩写词。

GIMP 有许多功能。它可以用作简单的绘画程序、专家级质量的照片修饰程序、创建数字艺术的工具、在线批处理系统、批量生产的图像渲染器、图像格式转换器等。

GIMP is expandable and extensible. It is designed to be augmented with plug-ins and custom data to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be scripted.

GIMP is a Free Software application covered by the General Public License version 3 [GPL]. The GPL provides users with the freedom to access and alter the source code that makes up computer programs.

1.1. Known Platforms

One of GIMP's strengths is its free availability on a wide range of operating systems and architectures. Most GNU / Linux distributions include GIMP as a standard application. GIMP is also available for other operating systems such as Microsoft Windows™ or Apple's macOS™ (Darwin). The platforms on which GIMP has been known to work include:

GNU/Linux™, Apple macOS™, Microsoft Windows™, OpenBSD™, NetBSD™, FreeBSD™, Solaris™, SunOS™, AIX™, HP-UX™, Tru64™, Digital UNIX™, OSF/1™, IRIX™, GNU/Hurd™, OS/2™, BeOS™, and its successor Haiku™.

GIMP is easily ported to other operating systems because of its source code availability. For further information visit the GIMP developers homepage. [GIMP-DEV].

1.2. History of GIMP

The first version of GIMP was written by Peter Mattis and Spencer Kimball in 1995. Over the years many other people have contributed by helping with development, testing, providing support, translating and writing documentation. A short history of GIMP is available online.

1.3. GIMP's Help system

The GIMP Documentation Team provides the information that tries to help you understand how to use GIMP. The User Manual is an important part of this help. The latest version is always available on the website of the Documentation Team [GIMP-DOCS] in HTML format. When using GIMP, context sensitive help is available by pressing the F1 key while the mouse is on top of a menu item or other part of GIMP's interface. Most dialogs will also show a help button that you can use to access the relevant part of the manual.

The manual in HTML format can also be installed locally on your computer. Installers are available for Windows, and on Linux your package manager may have a gimp-help package available. Though if your internet speed and bandwidth allow it, using the online manual is recommended since it is usually more up-to-date. When installing the local manual, you will have to adjust your help preferences to make use of the local copy.

1.4. 特性和功能

以下列表简要概述了GIMP为您提供的一些特性和功能:

  • 全套绘画工具,包括画笔、铅笔、喷枪、克隆等。
