+.SH NAME
+ppm2tiff \- create a
+.SM TIFF
+file from
+.SM PPM, PGM
+and
+.SM PBM
+image files
+.SH SYNOPSIS
+.B ppm2tiff
+[
+.I options
+] [
+.I input.ppm
+]
+.I output.tif
+.SH DESCRIPTION
+.I ppm2tiff
+converts a file in the
+.SM PPM, PGM
+and
+.SM PBM
+image formats to
+.SM TIFF.
+By default, the
+.SM TIFF
+image is created with data samples packed (\c
+.IR PlanarConfiguration =1),
+compressed with the Packbits algorithm (\c
+.IR Compression =32773),
+and with each strip no more than 8 kilobytes. These characteristics can be
+overridden, or explicitly specified with the options described below
+.PP
+If the
+.SM PPM
+file contains greyscale data, then the
+.I PhotometricInterpretation
+tag is set to 1 (min-is-black), otherwise it is set to 2 (RGB).
+.PP
+If no
+.SM PPM
+file is specified on the command line,
+.I ppm2tiff
+will read from the standard input.
+.SH OPTIONS
+.TP
+.B \-c
+Specify a compression scheme to use when writing image data:
+.B none
+for no compression,
+.B packbits
+for PackBits compression (will be used by default),
+.B lzw
+for Lempel-Ziv & Welch compression,
+.B jpeg
+for baseline JPEG compression,
+.B zip
+for Deflate compression,
+.B g3
+for CCITT Group 3 (T.4) compression,
+and
+.B g4
+for CCITT Group 4 (T.6) compression.
+.TP
+.B \-r
+Write data with a specified number of rows per strip; by default the number of
+rows/strip is selected so that each strip is approximately 8 kilobytes.
+.TP
+.B \-R
+Mark the resultant image to have the specified X and Y resolution (in
+dots/inch).
