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 (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.
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.
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.
