  Lossy data compression

  A lossy compression method is one where compressing data and then decompressing it retrieves data that is different from the original, but is close enough to be useful in some way. Lossy compression is most commonly used to compress multimedia data (audio, video, still images), especially in...

  Image file formats

  Image file formats are standardized means of organizing and storing images. This entry is about digital image formats used to store photographic and other images; (for disk-image file formats see Disk image). Image files are composed of either pixel or vector (geometric) data that are rasterized to...

  APNG

  The Animated Portable Network Graphics (APNG) file format is an unofficial extension to the Portable Network Graphics (PNG) specification. It allows for animated PNG files that work similarly to animated GIF files, while supporting 24-bit images and 8-bit transparency not available for GIFs. It...

  Vector graphics

  Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based on mathematical equations, to represent images in computer graphics. Vector graphics formats are complementary to raster graphics, which is the representation of images...

  PNG

  Portable Network Graphics (PNG) is a bitmapped image format that employs lossless data compression. PNG was created to improve upon and replace GIF (Graphics Interchange Format) as an image-file format not requiring a patent license. It is pronounced /ˈpɪŋ/ or spelled out as P-N-G. The PNG acronym...

• Lossless data compression

  Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. The term lossless is in contrast to lossy data compression, which only allows an approximation of the original data to be reconstructed, in exchange...

• Layered Image File Format

  Layered Image File Format (LIFF) is a file format used in the Openlab suite for microscope image processing. It is a proprietary format, but has an open, extensible form analogous to TIFF. It was specifically designed to contain a large number of high resolution images, and also all of the meta...

• Graphics File Formats

  Here is a summary of the most common graphics file format: Some file formats, e.g. PDF, allow both raster and vector graphics. This is because the underlying PostScript system of the Portable Document Format is designed to handle both methods of creating graphics. mnb

• GIS file formats

  A GIS file format is a standard of encoding geographical information into a file. They are created mainly by government mapping agencies (such as the USGS) or by GIS software developers. Metadata often includes:

• RAW image format

  A camera raw image file contains minimally processed data from the image sensor of either a digital camera, image or motion picture film scanner. Raw files are so named because they are not yet processed and therefore are not ready to be used with a bitmap graphics editor or printed. Normally, the...
