NAME
       thumbnail - create a TIFF file with thumbnail images

SYNOPSIS
       thumbnail [options] input.tif output.tif

DESCRIPTION
       The  thumbnail  command shows how to use the SubIFD tag (#330) to store thumbnail images. thumbnail copies a TIFF Class F facsimile file to
       the output file and, for each image, an 8-bit grayscale thumbnail sketch. The output file contains the thumbnail image with the	associated
       full-resolution page linked below with the SubIFD tag.

       By  default, thumbnail images are 216 pixels wide by 274 pixels high.  Pixels are calculated by sampling and filtering the input image with
       each pixel value passed through a contrast curve.

OPTIONS
       The following options are supported:

       -c	       Specify a contrast curve to apply when generating the thumbnail images. By default, pixel values are passed through a  lin-
		       ear contrast curve that simply maps the pixel value ranges. Alternative curves are as follows:

		       exp50		       50% exponential curve

		       exp60		       60% exponential curve

		       exp70		       70% exponential curve

		       exp80		       80% exponential curve

		       exp90		       90% exponential curve

		       exp		       pure exponential curve

		       linear		       linear curve

       -h	       Specify the height of thumbnail images in pixels.

       -w	       Specify the width of thumbnail images in pixels.

OPERANDS
       The following operands are supported:

       input.tif       The name of the input TIFF file.

       output.tif      The name of the output file.
