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 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.
GIMP's native format XCF is designed to store all information GIMP can contain about an image; XCF is named after the eXperimental Computing Facility where GIMP was authored. Import and export capability can be extended to additional file formats by means of plug-ins. XCF file size is extended to more than 4 GB since 2.9.6 and new stable tree 2 ...
Various Wikipedians have put together graphics tutorials. Some of these are still works in progress. It is preferred to work with open formats (such as PNG or SVG) and free licenses (such as public domain or GFDL) when possible. There are many free software programs available for creating and editing images.
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.
