GIMP - what is this program?

 GIMP - what is this program?


GIMP (abbreviation for GNU Image Manipulation Program) is a free image creation and editing program. GIMP is a very powerful tool, which is why many compare it to Photoshop (GIMP is a kind of free alternative to Photoshop).


The first editions of the program appeared in 1995. At first, GIMP was developed for UNIX-like operating systems, but then versions appeared for the Windows operating system. Today, the GIMP graphics editor is very popular among both Windows and Linux users, even many Linux distributions include GIMP by default (i.e. you don’t even need to install it).


GIMP was originally developed by Spencer Kimball and Peter Mattis. At the moment, quite a lot of developers have already contributed to the development of the project (if anyone is interested, you can find the full list of developers on the page of the authors of the official site).


GIMP is available for both 32-bit and 64-bit systems. GIMP supports many languages, including Russian, which is very good.


The main features of GIMP include:


Drawing, including a set of tools such as: brush, pencil, spray and others;

Transform: rotate, scale, warp and flip;

Layers, channels, filters;

Selection tools, for example: rectangular, elliptical, free selection, "magic wand" and other selection;

Tools for color correction;

Support for formats: GIF, JPEG, PNG, XPM, TIFF, TGA, MPEG, PS, PDF, PCX, BMP and others;

As well as many other useful features and functions.
