+ ppm2tiff [ options ] [ input.ppm ] +output.tif + |
+
| + |
+ 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. + |

+
+ 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 approximately 8 kilobytes. + |
++ | +
| + |
+
+ −R + |
++ |
+
+ Mark the resultant image to have the specified X and Y +resolution (in dots/inch). + |
