Fotoxx 5.3 (Default branch)
09-18-2008
Fotoxx is a program for improving digital photos. It allows you to navigate through large image directories using a window of thumbnail images, create HDR (high dynamic range) images by combining bright and dark images to improve details visible in both bright and dark areas, create panoramas by joining overlapped images, adjust brightness and color intensity independently for different underlying brightness levels, reduce fog or haze by removing "whiteness" and intensifying colors, rotate an image (level a tilted image or turn 90 degrees), remove red-eyes from electronic flash photos, sharpen, resize, or crop images, reduce noise in low-light photos, change color depth, and stretch an image by dragging the mouse.License: GNU General Public License v2Changes:|

THUMBNAIL(1) General Commands Manual THUMBNAIL(1) NAME
thumbnail - create a TIFF file with thumbnail images SYNOPSIS
thumbnail [ options ] input.tif output.tif DESCRIPTION
thumbnail is a program written to show how one might 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 greyscale 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
-w Specify the width of thumbnail images in pixels. -h Specify the height of thumbnail images in pixels. -c Specify a contrast curve to apply in generating the thumbnail images. By default pixels values are passed through a linear contrast curve that simply maps the pixel value ranges. Alternative curves are: exp50 for a 50% exponential curve, exp60 for a 60% exponen- tial curve, exp70 for a 70% exponential curve, exp80 for a 80% exponential curve, exp90 for a 90% exponential curve, exp for a pure exponential curve, linear for a linear curve. BUGS
There are no options to control the format of the saved thumbnail images. SEE ALSO
