tiffutil - manipulates tiff files

SYNOPSIS

tiffutil <option> [<arguments>] [-out <outfile>]

DESCRIPTION

tiffutil lets you manipulate TIFF files. The list of options (also available by running the program without any options) follows:

tiffutil -none infile [-out outfile] -lzw infile [-out outfile] -packbits infile [-out outfile] -jpeg [-fN] infile [-out outfile] -cat infile1 [infile2 ...] [-out outfile] -extract num infile [-out outfile] -info infile -verboseinfo infile -dump infile

-none, -lzw, -packbits, and -jpeg options specify the compression format to be applied to the images in the TIFF file. With JPEG compression it is possible to specify a compression factor between 1 and 255 using the -f argument; there should be no space between the "-f" and the number. By default this factor is 10.

-cat allows combining multiple TIFF files into one. The images are copied without any change in tag values.

-extract allows extracting an individual image from a TIFF file; specify num = 0 for the first image in the file.

-info prints information about TIFF images. -verboseinfo is the same, except most of the tables are displayed in full. -dump simply lists all of the tags in the file without trying to interpret them; it is handy when trying to figure out why a TIFF file won't load or display properly.

For options which write images out, the output goes to "out.tiff" unless an output file name is specified after a -out keyword. This keyword and the file must be the last items on the command line. -info, -verboseinfo, and -dump write their output to the standard output.

If there are multiple images in a TIFF file the specified operation will be performed on all of them.
