TIFFUTIL(1)						    BSD General Commands Manual 					       TIFFUTIL(1)

NAME
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] -cat infile1 [infile2 ...] [-out outfile] -catnosizecheck infile1 [infile2 ...] [-out outfile] -cathidpicheck infile1 [infile2 ...] [-out outfile] -extract num infile [-out outfile] -info infile -verboseinfo infile -dump infile -none, -lzw, and -packbits options specify the compression format to be applied to the images in the TIFF file. -none specifies no compres- sion; -packbits specifies PackBits compression; -lzw specifies standard Lempel-Ziv & Welch compression (no prediction scheme). -cat allows combining multiple TIFF files into one. The images are copied without any change in tag values. If the real sizes (pixel size divided by dpi) of the images being combined are not the same, a warning will be generated. This makes sure that NSImage can successfully choose the right size image out of the generated TIFF file. Use -catnosizecheck to bypass the size check. -cathidpicheck can be used to write an output file conforming to Apple's guidelines for resolution independent bitmap images, and will gener- ate warnings if the supplied images do not have the recommended size relationship. For best results, ensure that the larger file has a file- name of the form <basename>@2x.png. -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 prop- erly. 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. SECURITY NOTE: This version of tiffutil SHOULD NOT be used with untrusted files. CREDITS
