ppm2tiff1

Create a tiff file from ppm, pgm and pbm image files synopsis ppm2tiff [ options ] [ input.ppm ] output.tif

Overview

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 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 input.

Options

-c compress

Specify a compression scheme to use when writing image data: -c none for no compression, -c packbits for PackBits compression (will be used by default), -c lzw for Lempel-Ziv & Welch compression, -c jpeg for baseline JPEG compression, -c zip for Deflate compression, -c g3 for CCITT Group 3 (T.4) compression, and -c g4 for CCITT Group 4 (T.6) compression.

-r striprows

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 resolution

Mark the resultant image to have the specified X and Y resolution (in dots/inch).
