PPM2TIFF(1) LibTIFF PPM2TIFF(1) NAME ppm2tiff - create a TIFF file from PPM, PGM and PBM image files Synopsis ppm2tiff [ options ] [ input.ppm ] output.tif DESCRIPTION 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 (Planar- Configuration=1), compressed with the Packbits algorithm (Compres- sion=32773), and with each strip no more than 8 kilobytes. These char- acteristics 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 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 com- pression, -c jpeg for baseline JPEG compression, -c zip for De- flate 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 ap- proximately 8 kilobytes. -R resolution Mark the resultant image to have the specified X and Y resolu- tion (in dots/inch).
