pnmtosgi - Man Page

convert a PNM image to a SGI image file

Examples (TL;DR)




[-imagename Name]



This program is part of Netpbm(1).

pnmtosgi reads a PNM image as input and produces an SGI image file as output.  The SGI image will be 2-dimensional (1 channel) for PBM and PGM input, and 3-dimensional (3 channels) for PPM.


In addition to the options common to all programs based on libnetpbm (most notably -quiet, see Common Options ), pnmtosgi recognizes the following command line options:


Write an uncompressed file.

-rle (default)

Write a compressed (run length encoded) file.

-imagename name

Write the string "name" into the imagename field of the header. The name string is limited to 79 characters. If no name is given, pnmtosgi writes "no name" into this field.
