NAME
       img-tiff - Img, Tagged Image File Format (tiff)

DESCRIPTION
       The  package  img::tiff  is a sub-package of Img. It can be loaded as a part of the complete Img sup-port, support,
       port, via package require Img, or on its own, via package require img::tiff.

       Like all packages of Img it does not provide new commands, but extends the existing Tk command  image
       so  that  it  supports  files  containing  raster images in the Tagged Image File Format (tiff). More
       specifically img::tiff extends Tk's photo image type.

       The name of the new format handler is tiff.   This  handler  provides  new  additional  configuration
       options. See section TIFF OPTIONS for more detailed explanations.

       All of the above means that in a call like

       image create photo ?name? ?options?


       [1]    Image data in tiff format (options -data and -file) is detected automatically.

       [2]    The  format  name  tiff  is  recognized  by the option -format.  In addition the value for the
              option is treated as list and may contain any of the special options listed  in  section  TIFF
              OPTIONS.


TIFF OPTIONS
       The  handler provides three options, one for reading from a TIFF image, the other two influencing the
       writing of such.

       -index n
              This option is for reading from TIFF files containing more than one  image  (multi-page  TIFF.
              When specified it will read the n'th image in the data. The first image is at index 0 and will
              be read by default, i.e. when the option is not specified.

       -compression type
              This option specifies the type of compression to use when writing TIFF data. It has to be  one
              of none, jpeg, packbits, or deflate. The default is none.

       -byteorder type
              This  option specifies the byteorder to use when writing TIFF data. It has to be one of bigen-dian, bigendian,
              dian, littleendian, network, smallendian, or the  empty  string.  The  default  is  the  empty
              string.

              The  values  bigendian and network are aliases of each other, as are littleendian and smallen-dian. smallendian.
