An illustration of Adam7 interlacing over a 16×16 image An image being displayed using the Adam7 algorithm. Adam7 is an interlacing algorithm for raster images, best known as the interlacing scheme optionally used in PNG images. An Adam7 interlaced image is broken into seven subimages, which are defined by replicating this 8×8 pattern across ...
The GNU Image Manipulation Program, commonly known by its acronym GIMP (/ ɡ ɪ m p / ⓘ GHIMP), is a free and open-source raster graphics editor [3] used for image manipulation (retouching) and image editing, free-form drawing, transcoding between different image file formats, and more specialized tasks.
In computing, interlacing (also known as interleaving) is a method of encoding a bitmap image such that a person who has partially received it sees a degraded copy of the entire image. When communicating over a slow communications link , this is often preferable to seeing a perfectly clear copy of one part of the image, as it helps the viewer ...
PNG offers an optional 2-dimensional, 7-pass interlacing scheme—the Adam7 algorithm. This is more sophisticated than GIF's 1-dimensional, 4-pass scheme, and allows a clearer low-resolution image to be visible earlier in the transfer, particularly if interpolation algorithms such as bicubic interpolation are used.

The compressed files can be opened as normal image files. Since version 4, the image data can be compressed by zlib instead. The XCF file format is backward compatible (all versions of GIMP can open earlier versions' files) and in some cases, forward compatible. For example, GIMP 2.0 can save text in text layers while GIMP 1.2 cannot.
GTK (formerly GIMP ToolKit [2] and GTK+ [3]) is a free software cross-platform widget toolkit for creating graphical user interfaces (GUIs). [4] It is licensed under the terms of the GNU Lesser General Public License , allowing both free and proprietary software to use it.
G'MIC (GREYC's Magic for Image Computing) is a free and open-source framework for image processing. It defines a script language that allows the creation of complex macros. Originally usable only through a command line interface, it is currently mostly popular as a GIMP plugin, [2] and is also included in Krita.
