ppm2tiff - create a
TIFF file from
PPM, PGM and
PBM image files
options ] [
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
PPM file contains greyscale data, then the
PhotometricInterpretation tag is set to 1 (min-is-black), otherwise it is set to 2 (RGB).
PPM file 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,
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
