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 (PlanarConfiguration=1), compressed with the Lempel-Ziv and Welch algorithm (Compression=5), 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 grayscale data, the PhotometricInterpretation tag is set to 1 (min-is-black). Otherwise, the PhotometricInterpretation 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.
