PPM2TIFF(1) General Commands Manual 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 (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 Specify a compression scheme to use when writing image data: none for no compression, packbits for PackBits compression (will be used by default), lzw for Lempel-Ziv & Welch compression, jpeg for baseline JPEG compression, zip for Deflate compression, g3 for CCITT Group 3 (T.4) compression, and g4 for CCITT Group 4 (T.6) compression. -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 approxi- mately 8 kilobytes. -R Mark the resultant image to have the specified X and Y resolution (in dots/inch).

ppm2tiff - create a TIFF file from a PPM image file SYNOPSIS
ppm2tiff [options] [input.ppm] output.tif DESCRIPTION
ppm2tiff converts a file in the PPM image format to TIFF. By default, the TIFF image is created with data samples packed (PlanarConfigura- tion=1), compressed with the Lempel-Ziv and Welch algorithm (Compression=5), and with each strip no more than 8 kilobytes. These character- istics can be overridden or explicitly specified with the options described below. If the PPM file contains grayscale data, the PhotometricInterpretation tag is set to 1 (min-is-black). Otherwise, the PhotometricInterpre- tation tag is set to 2 (RGB). If no PPM file is specified on the command line, ppm2tiff reads from the standard input. OPTIONS
The following options are supported: -c Specify a compression scheme to use when writing image data: -c jpeg Baseline JPEG compression algorithm. -c lzw Lempel-Ziv and Welch algorithm. This is the default algorithm. -c none No compression. -c packbits PackBits compression algorithm. -c zip Deflate compression algorithm. -r Write data with a specified number of rows per strip. By default, the number of rows per 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 per inch. OPERANDS
The following operands are supported: input.ppm The name of the input file that contains PPM data. output.tif The name of the output file that contains TIFF data. ATTRIBUTES
