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


       package require Tk

       package require img::tiff  ?1.4?

       image create photo ?name? ?options?



       The  package img::tiff is a sub-package of Img. It can be loaded as a part of the complete
       Img support, 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.


       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 bigendian, 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
