ppm2tiff - create a TIFF file from PPM, PGM and PBM image files
ppm2tiff [ options ] [ input.ppm ] output.tif
ppm2tiff converts a file in the PPM, PGM and PBM image formats to TIFF. By default, the
TIFF image is created with data samples packed (PlanarConfiguration=1), compressed with
the Packbits algorithm (Compression=32773), and with each strip no more than 8 kilobytes.
These characteristics can be overridden, or explicitly specified with the options
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: none for no compres-
sion, packbits for PackBits compression (will be used by default), lzw for Lempel-
Ziv & Welch compression, jpeg for baseline JPEG compression, zip for Deflate com-
pression, g3 for CCITT Group 3 (T.4) compression, and g4 for CCITT Group 4 (T.6)
-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).
