thumbnail(1) User Commands thumbnail(1) 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. ATTRIBUTES
