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 ...
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 ...
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. It is extensible by means of plugins ...
FLIF supports a form of progressive interlacing (a generalization of the Adam7 algorithm) with which any partial download (greater than couple hundred bytes [5]) of an image file can be used as a lossy encoding of the entire image.
The Adam7 interlacing allows an early preview, even when only a small percentage of the image data has been transmitted — useful in online viewing applications like web browsers. PNG can store gamma and chromaticity data, as well as ICC profiles , for accurate color matching on heterogeneous platforms.

GEGL is modelled after a directed acyclic graph, where each node represents an image operation (called "operators" or "ops"), and each edge represents an image.Operations can in general take several input images and give several output images, which corresponds to having several incoming edges (images) and several outgoing edges (images) at a given node (operation).
The software mainly consists of a number of command-line interface utilities for manipulating images. ImageMagick does not have a robust graphical user interface to edit images as do Adobe Photoshop and GIMP, but does include – for Unix-like operating systems – a basic native X Window GUI (called IMDisplay) for rendering and manipulating images and API libraries for many programming languages.
