![]() ![]() It is used to describe image data that comes from scanners, frame-grabbers, paint programs, and photo-retouching programs. It is a rich format that can take advantage of many image requirements but is not tied to particular input or output devices. It provides numerous options-for example, several different compression schemes and comprehensive information for color calibration. It is designed so that private and special-purpose information can be included.Ī single TIFF file can include several images, each of which is characterized by tags whose values define particular properties of the image. Most tags contain integers, but some contain ASCII text-and provision is made for tags containing floating-point and rational numbers. Software program that generated the image Page name (typically used for page number) Others: uncompressed, byte-oriented run-length coding Samples per pixel (RGB only): normally 3 for RGB imagesĬolor map (palette-color only): specifies a color table for the imageīilevel: uncompressed, packed into bytes as tightly as possible, CCITT fax compression standard, byte-oriented run-length coding Photometric interpretation (black-on-white or white-on-black)īits per sample (1 for bilevel, 4 or 8 for grayscale) Baseline TIFF has a dozen or so mandatory tags that give physical characteristics and features of images: their dimensions, compression, various metrics associated with the color specification, and information about where they are stored in the file. Make and model of the equipment used for scanningĪdditional features go far beyond the baseline illustrated in Table 6.5 and users can define new TIFF tags and compression. ![]() ![]() This makes the TIFF format even more flexible than the official list of extensions given in the standard, although naturally care needs to be taken to ensure that the software used to read and write image files is conversant with the tags they use. #Tiff image compression software software# #Tiff image compression software software#.#Tiff image compression software how to#. ![]()
