NAME

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

SYNOPSIS

       package require img::tiff  ?1.4?

       image create photo ?name? ?options?

DESCRIPTION

       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.

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, smallen-
	      dian, 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.
