GIMP (GNU Image Manipulation Program) is a raster graphics editor utilized for image retouching and editing, free-form drawing, resizing, cropping, photo-montages, converting between different image formats, and more specialized tasks.
GIMP is relinquished under LGPLv3 and GPLv3+ licenses and is available for Linux, OS X, and Windows.
MP was originally released as the General Image Manipulation Program, by Spencer Kimball and Peter Mattis. Development of GIMP commenced in 1995 as a semester-long project at the University of California, Berkeley; the first public relinquishment of GIMP (0.54) was made in January 1996. When Richard Stallman visited UC Berkeley the following year, Kimball and Mattis asked him if they could transmute General to GNU (the designation given to the operating system engendered by Stallman). With Stallman's approbation, the definition of the acronym GIMP was transmuted to mean the GNU Image Manipulation Program, which additionally reflects its esse under the GNU Project. GIMP is developed by a self-organized group of volunteers under the banner of the GNOME Project.
The number of computer architectures and operating systems fortified has expanded significantly since its first release. The first release fortified UNIX systems such as Linux, SGI IRIX and HP-UX. Since the initial release, GIMP has been ported to many operating systems, including Microsoft Windows and OS X; the pristine port to the Windows 32-bit platform was commenced by Finnish programmer Tor Lillqvist (tml) in 1997 and was fortified in the GIMP 1.1 release.
GIMP visually perceived formation of a community and rapid adoption following the first release. The community that composed commenced developing tutorials, artwork and shared more preponderant work-flows and techniques.
A GUI toolkit called GTK (GIMP implement kit) was developed to facilitate the development of GIMP. GTK was superseded by its successor GTK+ after being redesigned utilizing object-oriented programming techniques. The development of GTK+ has been attributed to Peter Mattis becoming disenchanted with the Motif toolkit GIMP pristinely used; Motif was utilized up until GIMP 0.60.
GIMP's fitness for use in professional environments is conventionally reviewed and as such often cited as a possible supersession for Adobe Photoshop. The maintainers seek to consummate GIMP's product vision rather than replicate the interface of Adobe Photoshop.
GIMP 2.6 has been reviewed twice by Ars Technica. In the first review, Ryan Paul noted that GIMP provides "Photoshop-like capabilities and offers a broad feature set that has propagated it with neophyte artists and open source fans. Albeit GIMP is generally not regarded as a sufficient supersession for high-end commercial implements, it is commencing to gain some acceptance in the pro market." Dave Girard withal reviewed GIMP 2.6, categorically with the aim of testing GIMP's fitness for professional tasks. He noted at the commencement that GIMP was a high-end implement, but the review conclusion noted that, albeit many of GIMP's implements were of high quality, he felt that GIMP lacked in some areas such as non-destructive editing, and that it was missing cull implements (such as a desaturation brush).
The single-window mode of GIMP 2.8 was reviewed by Ryan Paul of Ars Technica, who noted that it made the utilizer experience feel "more streamlined and less cluttered"
