![]() ![]() ![]() The 8-byte TIFF file header contains the following information:īytes 0-1: The byte order used within the file. An IFD contains information about the image as well as pointers to the actual image data. ![]() The file begins with an 8-byte image file header that points to an image file directly (IFD). The largest possible TIFF file is 2**32 bytes in length. ![]() A TIFF file begins with an 8-byte header where the bytes are number from 0 to N. TIFF file format is extensible and has underwent several revisions that allows the inclusion of an unlimited amount of private or special-purpose information. In 1994, Adobe Systems acquired Aldus and the specifications are now available and maintained by Adobe Systems. Revision 6.0 of TIFF file formats were published in 1992 after that. A major Revision 5.0 was published in 1988 that added support for palette color images and LZW compression. The initial version of TIFF file format specifications can be labeled as Reivision 3.0 as there were two earlier draft releases. Starting with support for only binary image format, the format evolved to the support of grayscale and color images with the passage of time. The primary purpose of TIFF file format was to provide a common scanned image file format for all the desktop scanner vendors. TIFF file format was initially created by Aldus Corporation in the fall of 1986, after a series of meetings with various scanner manufacturers and software developers. The format is not machine dependent and is free from bounds like processor, operating system, or file systems. It supports lossy as well as lossless compression schemes to choose between space and time for applications using the format. It is capable of describing bilevel, grayscale, palette-color and full-color image data in several color spaces. TIFF or TIF, Tagged Image File Format, represents raster images that are meant for usage on a variety of devices that comply with this file format standard. ![]()
