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 (PlanarConfiguration=1), compressed with the Lem
pel-Ziv & Welch algorithm (Compression=5), and with each
strip no more than 8 kilobytes. These characteristics can
be overriden, or explicitly specified with the options
described below
If the PPM file contains greyscale data, then the Photo_
metricInterpretation tag is set to 1 (min-is-black), oth
erwise 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 compression algorithm, -c jpeg for
the baseline JPEG compression algorithm, -c zip for
the Deflate compression algorithm, and -c lzw for
Lempel-Ziv & Welch compression (the default).
-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 resolution (in dots/inch).
