PPM2TIFF(1)PPM2TIFF(1)NAMEppm2tiff - create a TIFF file from a PPM image file
SYNOPSISppm2tiff [ options ] [ input.ppm ] output.tif
DESCRIPTIONppm2tiff converts a file in the PPM image format to TIFF. By default,
the TIFF image is created with data samples packed (PlanarConfigura‐
tion=1), compressed with the Lempel-Ziv & Welch algorithm (Compres‐
sion=5), and with each strip no more than 8 kilobytes. These charac‐
teristics can be overridden, or explicitly specified with the options
described below
If the PPM file contains greyscale data, then the PhotometricInterpre‐
tation tag is set to 1 (min-is-black), otherwise it is set to 2 (RGB).
If no PPM file is specified on the command line, ppm2tiff will read
from the standard input.
OPTIONS-c Specify a compression scheme to use when writing image data: -c
none for no compression, -c packbits for the PackBits compres‐
sion algorithm (the default), -c jpeg for the baseline JPEG com‐
pression algorithm, -c zip for the Deflate compression algo‐
rithm, and -c lzw for Lempel-Ziv & Welch compression.
-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.
-R Mark the resultant image to have the specified X and Y resolu‐
tion (in dots/inch).
