usage: tiffcp [options] input… output
where options are:
-a append to output instead of overwriting
-o offset set initial directory offset
-p contig pack samples contiguously (e.g. RGBRGB…)
-p separate store samples separately (e.g. RRR…GGG…BBB…)
-s write output in strips
-t write output in tiles
-8 write BigTIFF instead of default ClassicTIFF
-i ignore read errors
-b file[,#] bias (dark) monochrome image to be subtracted from all others
-,=% use % rather than , to separate image #’s (per Note below)

-r # make each strip have no more than # rows
-w # set output tile width (pixels)
-l # set output tile length (pixels)

-f lsb2msb force lsb-to-msb FillOrder for output
-f msb2lsb force msb-to-lsb FillOrder for output

-c lzw[:opts] compress output with Lempel-Ziv & Welch encoding
-c zip[:opts] compress output with deflate encoding
-c lzma[:opts] compress output with LZMA2 encoding
-c jpeg[:opts] compress output with JPEG encoding
-c jbig compress output with ISO JBIG encoding
-c packbits compress output with packbits encoding
-c g3[:opts] compress output with CCITT Group 3 encoding
-c g4 compress output with CCITT Group 4 encoding
-c sgilog compress output with SGILOG encoding
-c none use no compression algorithm on output
-x force the merged tiff pages in sequence

Group 3 options:
1d use default CCITT Group 3 1D-encoding
2d use optional CCITT Group 3 2D-encoding
fill byte-align EOL codes
For example, -c g3:2d:fill to get G3-2D-encoded data with byte-aligned EOLs

JPEG options:
# set compression quality level (0-100, default 75)
r output color image as RGB rather than YCbCr
For example, -c jpeg:r:50 to get JPEG-encoded RGB data with 50% comp. quality

LZW, Deflate (ZIP) and LZMA2 options:
# set predictor value
p# set compression level (preset)
For example, -c lzw:2 to get LZW-encoded data with horizontal differencing,
-c zip:3:p9 for Deflate encoding with maximum compression level and floating
point predictor.

Note that input filenames may be of the form filename,x,y,z
where x, y, and z specify image numbers in the filename to copy.
example: tiffcp -c none -b esp.tif,1 esp.tif,0 test.tif
subtract 2nd image in esp.tif from 1st yielding uncompressed result test.tif
