- .TH PPM2TIFF 1 "March 1, 2006" "libtiff"
- .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).
