NAMEppm2tiff - create a
SYNOPSISppm2tiff [ options ] [ input.ppm ] output.tif
DESCRIPTIONppm2tiff converts a file in the
PBMimage formats to
TIFF.By default, the
TIFFimage 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
PPMfile contains greyscale data, then the PhotometricInterpretation tag is set to 1 (min-is-black), otherwise it is set to 2 (RGB).
PPMfile is specified on the command line, ppm2tiff will read from the standard input.
- 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.
- 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.
- Mark the resultant image to have the specified X and Y resolution (in dots/inch).
