ppm2tiff - create a TIFF file from a PPM image file
ppm2tiff [ options ] [ input.ppm ] output.tif
ppm2tiff 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 Lempel-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 PhotometricInterpretation 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
-c Specify a compression scheme to use when writing image data: -c none for no com-
pression, -c packbits for the PackBits compression algorithm, -c jpeg for the base-
line 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).
