GIMP (GNU Image Manipulation Program, previously General Image Manipulation Program) is a free software, raster graphics editor used to process digital graphics and photographs. Typical uses include creating graphics and logos, resizing and cropping photos, altering colors, combining multiple images, removing unwanted image components, and converting between different image formats.[2] Along with these uses, GIMP is widely used as a tool for photo enhancement. GIMP can also be used to create basic animated images in GIF format. It is often used as a replacement for Adobe Photoshop, the most widely used bitmap editor in the printing and graphics industries; however, it is not designed to be a Photoshop clone.[3] The project's mascot is named Wilber.

The project was started in 1995 by Spencer Kimball and Peter Mattis and is now maintained by a group of volunteers under the auspices of the GNOME Project.[4] The current version of GIMP works with numerous operating systems, including most Unix variants, Microsoft Windows and Mac OS X. Released under the terms of the GNU General Public License, GIMP is free software.

[edit] Features

Brushes dialog in GNOME

GIMP's manipulation tools can be accessed via the toolbox, menu paths, and dialog boxes (which can be grouped in docks). They include filters and brushes, as well as transformation, selection, layer and masking tools.

[edit] Color support

GIMP also has a palette with RGB, HSV, color wheel, CMYK, and mixing modes, plus tools to pick colors from the image with various averaging options. There is support for hexadecimal color codes (as used in HTML). "CMYK" colors are immediately translated into RGB when used; GIMP does not have any built-in support for CMYK mixtures that cannot be represented in RGB, such as rich blacks, though they can be simulated to a limited extent with third-party add-ons.[citation needed]

GIMP supports gradients, which integrate into its other tools (such as brushes and fills) to shade image areas with automated color blending. It includes a variety of built-in gradients, and as with the brushes, also allows the user to customize and create their own gradient fills.

[edit] Selection and masking tools

GIMP can perform rectangular or circular selection, freehand selection, and "by color" selection. Alternatively, the Smart Selection tool, known as the "Magic Wand", can be used to select contiguous regions. The Intelligent Scissors (iScissors) tool can be used to auto-create paths between regions defined by strong color-changes. the 'Foreground select' tool is available since 2.4 uses Simple Interactive Object Extraction (SIOX) to select an object in the foreground with some few mouse strokes by the user.

GIMP has support for layers, including transparent layers, which can be shown, hidden, or made semitransparent. It also supports transparent and semitransparent images. Channels add different types of opacity and color effects to images.

[edit] Paths

Paths containing line segments or Bézier curves can be created using the Path tool. Paths can be named, saved, and painted (or "stroked") with brushes, patterns, or various line styles. Paths can also be used to create complex selections.

[edit] Effects, scripts, and filters

GIMP has approximately 150 standard effects and filters, including Drop Shadow, Blur, Motion blur and Noise.

GIMP operations can be automated with scripting languages. The Script-Fu extension language based on Scheme is built in (originally SIOD but switched to TinyScheme as of GIMP 2.4.), and external Perl, Python, or Tcl can be used. Ruby support is in experimental development. These scripts and plugins for GIMP can be used interactively, or combined non-interactively.

[edit] Development

GIMP is primarily developed by unpaid volunteers. The GIMP project has a development branch of GIMP where new features are added regularly and a stable branch which only receives bug fixes between major versions. Adopting a scheme used by many other free software projects, the stable and development branches are denoted with even and odd numbers respectively after the first decimal point in the version number. The old series last version is 2.4.7. The current stable version of GIMP is 2.6.5 (as of Feb. 16, 2009.) Major changes from version 1.2 to version 2.2 included a more polished user interface, further separation of the user interface and back-end and the ability to use brushes that would normally only be able to be used on Photoshop programs. Major changes from version 2.2 to version 2.4 included color management support, scalable brushes, new and rewritten selection tools and overall user interface changes.[5], Major changes from version 2.4 to version 2.6 included a new layout of windows and tool palettes, new brush dynamics features, basic integration of the General Graphical Library (though users won't see any effect by default), improved free selection tool and a new PSD import plug-in that can read ICC color profiles.[6] The use of GEGL addresses some fundamental design limitations of the previous version that prevented many enhancements such as native CMYK support.

GIMP's user interface is built using GTK+, a widget toolkit originally written for the program. GTK+, as the GIMP Toolkit, was initially a part of the GIMP source tree, but has since been refactored due to its usefulness outside the scope of GIMP. GTK+ is also used as the widget toolkit for the GNOME desktop environment. GTK+ was intended as a replacement for Motif, a proprietary toolkit on which GIMP originally depended. GIMP and GTK+ were originally designed for the X Window System running on Unix-like operating systems, but have since been ported to Microsoft Windows, Mac OS X, and SkyOS.

GIMP originally stood for General Image Manipulation Program.[7] Its creators, Spencer Kimball and Peter Mattis, began developing GIMP as a semester-long project at the University of California, Berkeley in 1995.[8] The name was changed to the GNU Image Manipulation Program in 1997, after Kimball and Mattis had graduated, when it became an official part of the GNU Project.[9]

[edit] GIMP 0.54

GIMP 0.54 was released in January 1996.[10][11] It required X11 displays, an X-server that supported the X shared memory extension and Motif 1.2 widgets. It supported 8, 15, 16 and 24-bit color depths, dithering for 8-bit displays and could view images as rgb color, grayscale or indexed color. It could simultaneously edit multiple images, zoom and pan in real-time, and supported GIF, JPEG, PNG, TIFF and XPM images.[7]

Even at this early stage of development GIMP functionality was extensive. It could select regions using rectangle, ellipse, free, fuzzy, bezier, and intelligent selection tools, and rotate, scale, shear and flip images. It had bucket, brush and airbrush painting tools, and could clone, convolve, and blend images. It had text tools, effects filters (such as blur and edge detect), and channel and color operations (such as add, composite, decompose). The plugin system allowed for addition of new file formats and new effect filters. It supported multiple undo and redo operations.[7]

It ran on Linux 1.2.13, Solaris 2.4, HP-UX 9.05, and SGI IRIX operating systems.[7] It was rapidly adopted by users,[12][13] who created tutorials, displayed artwork and shared techniques.[10][11] An early success for GIMP was the Linux penguin Tux, as drawn by Larry Ewing using Gimp 0.54.[14] By July 5, 1996 the volume of messages posted to the mailing list had risen and the mailing list was split into two lists, gimp-developer and gimp-user. Currently, user questions are directed to the gimpnet IRC channel.[10][11]

[edit] GIMP 0.60

GIMP 0.60 was released on June 6, 1997[15] using the GNU General Public License.[16] According to the release notes, Peter Mattis was working for Hewlett-Packard and Spencer Kimball was working as a Java programmer.[17]

GIMP 0.60 no longer depended on the Motif toolkit. Improvements had been made to the painting tools, airbrush, channel operations, palettes, blend tool modes, image panning and transformation tools. The editing work flow was improved by enabling rulers, cutting and pasting between all image types, cloning between all image types and ongoing development of a layers dialog.

New tools included new brushes (and a new brush file format), grayscale and RGB transparency,"Bucket fill" patterns and a pattern selection dialog, integrated paint modes, border, feather and color selectors, a pencil and eraser paint tool, gamma adjustments and a limited layer move tool.

The new widgets were managed by Peter Mattis and were called GTK for GIMP toolkit and GDK for GIMP drawing kit.[17]

[edit] GIMP 0.99

The biggest change in the GIMP 0.99 release was in the GIMP toolkit (GTK). GTK was redesigned to be object oriented and renamed from GTK to GTK+. The pace of development slowed when Spencer Kimball and Peter Mattis found employment.[10][11]

[edit] GIMP 1.0

GIMP 1.0.0 was released on June 2, 1998[18] GIMP and GTK+ split into separate projects during the GIMP 1.0 release. GIMP 1.0 included a new tile based memory management system which enabled editing of larger images and a change in the plug-in API (Application programming interface) allowed scripts to be safely called from other scripts and to be self documenting. GIMP 1.0 also introduced a native file format (xcf) with support for layers, guides and selections (active channels).

An official website was constructed for GIMP during the 1.0 series, designed by Adrian Likins and Jens Lautenbacher, now found at classic.gimp.org which provided introductory tutorials and additional resources.[19] On April 13, 1997, GIMP News was started by Zach Beane, a site that announced plug-ins, tutorials and articles written about GIMP. May 1997, Seth Burgess started GIMP Bugs, the first 'electronic bug list'.[10][11]

Marc Lehmann[20] developed a perl scripting plug-in.[21][22][23] Web interfaces were possible with the GIMP 1.0 series, and GIMP Net-fu[24] can still be used for online graphics generation.[25]

[edit] GIMP 1.1

The GIMP 1.1 series focused on fixing bugs and porting to Windows. No official release occurred during this series. Following this the odd numbered series (eg 1.1) of GIMP releases were considered unstable development releases and even numbered releases (eg 1.2) were considered stable releases. By this time, GTK+ had become a significant project and many of GIMP's original developers turned to GTK+ development. These included Owen Taylor (author of GIMP ifsCompose),[26] Federico Mena,[27] Tim Janik,[28] Shawn Amundson and others. GNOME also attracted GIMP developers. The primary GIMP developers during this period were Manish Singh, Michael Natterer[29] Sven Neumann[30] and Tor Lillqvist[30] who primarily fixed issues so that GIMP could run on Win32.[31]

[edit] GIMP 1.2

GIMP 1.2.0 was released on December 25, 2000. GIMP 1.2 had a new development team of Manish Singh, Sven Neumann and Mitch Natterer and others. GIMP 1.2 offered internationalization options, improved installation dialogs, many bug fixes (in GIMP and GTK+), overhauled plug-ins, reduced memory leaks and reorganized menus.[32] New plug-ins included GIMPressionist, Sphere Designer, by Vidar Madsen,[33] Image Map by Maurits Rijk[34] GFlare by Eiichi Takamori, Warp by John P. Beale, Stephen Robert Norris and Federico Mena Quintero, Sample Colorize and Curve Bend by Wolfgang Hofer. New tools included a new path tool, a new airbrush tool, a resizable toolbox, enhanced pressure support, a measure tool, dodge, burn and smudge tools. New functionality included image pipes, jpeg save preview, a new image navigation window, scaled brush previews, selection to path, drag'n'drop, quickmask, a help browser, tear-off menus and the waterselect plug-in was integrated into the color-selector.[32]

The 1.2 series was the final GIMP 1 series.

[edit] GIMP 2.0

GIMP 2.0.0 was released on March 23, 2004. The biggest visible change was the transition to the GTK+ 2.x toolkit.

[edit] GIMP 2.4

Major revisions in interface and tools were made available with the GIMP 2.4.0 release on October 24, 2007. Rewritten selection tools, use of the Tango style guidelines for a polished UI on all platforms, a foreground selection tool, and support for the ABR brush filetype along with the ability to resize brushes were some of the many updates.

[edit] GIMP 2.6

More major revisions in interface and tools were made available with the 2.6.0 release on October 1, 2008. There were big changes in the UI, free select tool and brush tools, and lesser changes in the code base. Also partial, tool level integration of GEGL was enacted that is supposed to lead to higher color depths as well as non-destructive editing in future versions.[35] Starting from the first bugfix version, GIMP 2.6.1, the "The Utility Window Hint", otherwise known as the "One Window Gimp" became available for Microsoft Windows, as opposed to only being supported in GNOME.

[edit] Distribution

GIMP 2.4.5 running on Windows Vista

GIMP is available for a variety of operating systems and computer architectures. There are a number of variations and derivative programs, including ports to other operating systems and forks with task- or OS-specific modifications. The GIMP website does not distribute compiled versions of GIMP, only the project's source code.

GIMP 2.2.8 running under X11 on Mac OS X

GIMP is included as the standard image editor on most general purpose Linux distributions, including Debian, Ubuntu, Mandriva, SUSE, and Fedora.

A port of GIMP to Microsoft Windows was started by Finnish programmer Tor "tml" Lillqvist in 1997. The GIMP website links to binary installers compiled by Jernej Simončič for the platform.[36]

[edit] Variants

GIMPVS is a GTK+ and GIMP Distribution compiled using Microsoft compilers. The Distribution aims at providing artists a stable GIMP on Microsoft platforms and developers access to GTK+ and GIMP development directly from Microsoft Visual Studio (2005 and 2008 editions). The latest GTK+ libraries are included GTK+ 2.15.0 comes ready to use in both Debug and Release versions[37]

Seashore is a program based on GIMP for Mac that uses the native Cocoa interface in Mac OS X. The program is currently in beta (0.1.9) and includes only a small subset of the many filters available in GIMP.

Gimp.app provides a self-contained application bundle of GIMP for Mac OS X. Gimp.app has many features that Seashore does not have, but being built upon the GTK+ for its GUI features, it requires a version of Apple's X11 to run it.[38]

A project named osx-gimp provides native builds of GIMP on Mac OS X using GTK+ built for Quartz. It is mostly functional, but there is currently limited support for the Quartz backend of GTK+, and it is considered a beta version.[39]

CinePaint, formerly known as "Film Gimp", is a fork of GIMP version 1.0.4, used for frame-by-frame retouching of feature film. The present "Film Gimp" version supports up to 32-bit IEEE-floating point color depth/channel. CinePaint supports color management and HDR. CinePaint is used primarily within the film industry due mainly to its support of high-fidelity image formats.

GIMP Portable is a program based on GIMP but made to be completely portable. It is run by: John T. Haller and can be found at: GIMP Portable

[edit] Interface and usability

As an application originally intended only for the X Window System, GIMP does not attempt to manage its own windows, but entirely delegates this responsibility to the window manager. GIMP uses a (controlled) single document interface, and it also uses multiple windows for its tools, color palette, and so forth. This behavior is not well supported on most platforms because most programs use either a multiple document interface or an SDI with integrated toolbars. The GIMP approach avoids the MDI problem of windows being constrained within a larger window, without requiring the additional code that most other applications use to solve this problem; but it is also a frequent cause of criticism. It generally leads to desktop clutter, and to the situation where the toolbox and layer windows end up hidden behind other unrelated applications, forcing users to manage the windows themselves. A partial solution is available by choosing a window manager that implements certain very particular functionality; however, this functionality is not available at all on Microsoft Windows, and is also not present in all Linux window managers. In recognition of these issues, the GIMP developers have been investigating other solutions, and future versions of the program are expected to introduce a different interface.

GIMPshop is a modification to GIMP, rearranging its user interface to mimic that of Adobe Photoshop by renaming functions and rearranging menus; on Windows this also includes the use of a multiple document interface.

GIMP is often criticized as having other usability problems.[40] A special edition called Instrumented GIMP was created at the University of Waterloo, which tracks and reports user interaction with the program, to generate statistics to guide future improvements.

[edit] Comparison and compatibility with Adobe Photoshop

GIMP is sometimes suggested as a replacement for the Adobe Photoshop software product. Thus, comparisons between the two are often a topic of spirited debate.[41] There are significant differences between the two packages. For example, GIMP plugins and scripts are not compatible with Photoshop. GIMP features offer no or (with the PSPI plug-in) very weak support for plugins designed for Photoshop, such as 8BF filters.[42]

GIMP's native XCF file format is not widely supported by other applications, but GIMP can read and write most Photoshop native PSD format files.

GIMP features support for 8-bit per-channel images, compared to Photoshop's support for 8, 16, and 32-bit per-channel images. Its Intelligent Scissors are similar to Photoshop's Magnetic Lasso tool, and some basic tools and filters have identical functionality in both.

GIMP and Photoshop differ in their color management features in ways that matter to some users. Photoshop has support for 16-bit, 32-bit, and floating point images,[43] support for the Pantone color matching system, or spot color and support for color models other than RGB(A) and greyscale, such as CMYK and CIE XYZ. GIMP, like other open source applications, does not support Pantone numbers for spot colors;[44] it has rudimentary CMYK support via a plugin.[45] Photoshop features extensive gamma correction support.

In addition, Photoshop contains several productivity features and tools not supported by GIMP, such as native support for Adjustment layers, which are layers that act like filters, layer styles and text blending options like drop shadow and glow, undo history "snapshots" that persist between sessions, the history brush tool, folders in the layer window. GIMP also requires basic programming knowledge to build an automation upon it, usually Script-Fu (scheme) or Python-Fu, while Photoshop can record the user's actions and repeat them with a "Play" button.

GIMP's open development model means that plugin development is not limited by developers; by comparison, access to Adobe Photoshop's SDK requires registration.[46]

[edit] File types

GIMP has support for opening and saving to a large number of different file formats.[47] Its native format is XCF, named after the computing facility where GIMP was authored.

GIMP has read/write support for popular image formats such as BMP, JPEG, PNG, GIF and TIFF, along with the file formats of several other applications such as Autodesk flic animations, Corel Paint Shop Pro images, and Adobe Photoshop Documents. Other formats with read/write support include PostScript documents, X bitmap image and Zsoft PCX. GIMP can also read and write path information from SVG files, and read/write ICO Windows icon files.

GIMP can import Adobe PDF documents and the raw image formats used by many digital cameras, but cannot save to these formats.

GIMP can export to MNG layered image files (linux version only) and HTML (as a table with colored cells), C source code files (as an array) and ASCII Art (using a plugin to represent images with characters and punctuation making up images), though it cannot read these formats.

[edit] Wilber

Wilber, the mascot of GIMP

Wilber is the official mascot of GIMP. Wilber was created sometime before September 25, 1997, by Tuomas Kuosmanen, known as tigert, with GIMP. He received additional accessories from other GIMP developers, which can be found in the Wilber Construction Kit, included in the GIMP source code as /docs/Wilber_Construction_Kit.xcf.gz.

The category icon for GIMP stories on Slashdot uses Wilber which includes a subtle moving eyes animation. It is the only animated category icon on Slashdot.
