A short while ago I requested information on graphics formats to try and make sense of them all. Wow! Seems a lot of people wanted to know too! What follows is a rough attempt at this, with *MUCH* missing. Please send me your comments/amendments/more info. Thanks to everyone who's helped in this so far. -------------------------------------------------------------------------- Toby Howard Computer Science Department, University of Manchester, U.K. Lecturer janet: toby@uk.ac.man.cs.p1 internet: toby%p1.cs.man.ac.uk@nsfnet-relay.ac.uk earn/bitnet: toby%uk.ac.man.cs.p1@UKACRL uucp: ...!ukc!mup1!toby voice: +44 61-275-6274 -------------------------------------------------------------------------- Here we go.... First the ones which seem to be the most popular: CGM - FIPS PUB 128 (Federal Information Processing Standard in the United States). Computer Graphics Metafile. Used in transfer of picture type files (flat vector data). CCITT - this is a common raster format, commonly known as the facsimile coding scheme for Group 3 and 4 facsimile apparatus. CCITT stands for Committe Consultatif International de Telegraphique et Telephonique (or in english, International Consultative Committee on Telegraphy and Telephony). The United States Department of Defense has mandated with Military Standards (MIL-STD-1840A and MIL-STD-28000) that this is the data interchange requirements for raster data. GIF - 'GIF' (tm) is CompuServe's standard for defining generalized color raster images. This 'Graphics Interchange Format' (tm) allows high-quality, high-resolution graphics to be displayed on a variety of graphics hardware and is intended as an exchange and display mechanism for graphics images. IGES - ANSI standard Y14.26M, defines a neutral file format and a standard set of entities which are used to transfer and store product definition data created by computer aided design and engineering systems. Contains object information and can be 2 or 3 D images. NFF - ASCII scene description encoding, for the Standard Procedural Database PCX - PC Paintbrush PBM - Format used by the Portable Bitmap Manipulation package (Jeff Poskanzer). This is a collection of programs for manipulating raster images and converting between many different formats. SUN raster - has magic number for identification, multiple types identified in the header, 1-24 bit depth images and colour maps may be present. See rasterfile.h on a Sun. TIFF - Tag Image File Format. Created by Microsoft/Aldus. XBM - X bitmap ---------------------------------------------------- Summary List ------------ The following is excerpted from a document prepared by Keith Graham, the author of a popular P/D software package called "Optiks". Optiks is more or less a "graphics spreadsheet" concept, in that it can read in many formats, and export quite a few. The document contains a listing of many graphics formats, primarily those that are most commonly found on PC's. The following is a partial list of the many graphics formats that are available. Keith Graham started the list, and H. F. Van Brink added to it.
