NAME

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

SYNOPSIS

       package require Tk

       package require img::tiff  ?1.4?

       image create photo ?name? ?options?

DESCRIPTION

       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.

       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.

       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 the following options:

       -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 string
              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 string
              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
              smallendian.
