NAME

       pnmtorle - convert a Netpbm image file into an RLE image file.

SYNOPSIS

       pnmtorle

       [-header] [-verbose] [-alpha] [-outfile=outfile] [pnmfile]

       Minimum unique abbreviation of option is acceptable.  You may use double hyphens instead of single hyphen
       to  denote  options.  You may use white space in place of the equals sign to separate an option name from
       its value.

DESCRIPTION

       This program is part of Netpbm(1).

       This program converts Netpbm image files into Utah RLE image files.  You can include a transparency mask.
       If the input is a multiple image file, the output consists of several concatenated RLE images.

       pnmfile is the name of the Netpbm image input file.  If you don't specify this argument,  input  is  from
       Standard Input.

       The  RLE  file  will  contain  either a three channel color image (24 bits) or a single channel grayscale
       image (8 bits) depending upon the type of Netpbm input.  If the Netpbm input is color, the RLE output  is
       3  channel  24  bit color.  If the Netpbm input is grayscale or black and white, the RLE output is single
       channel grayscale.

OPTIONS

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

       -verbose
                This option will cause pnmtorle to operate in verbose mode.  The
                program writes header information to Standard Error.  Actually, there is not
                much header information stored in a Netpbm file, so this information is
                minimal.

              Before Netpbm 10.98 (March 2022), this option is just -v.

       -header
              This option causes the program to dump the header of the Netpbm image to be Standard Error without
              converting the file.  It is equivalent to using the -verbose option except that no file conversion
              takes place.

              Before Netpbm 10.98 (March 2022), this option is just -h.

       -alpha This  option  causes  pnmtorle  to  include  a  transparency  channel  in  the  output image.  The
              transparency channel is based  on  the  image:  Wherever  a  pixel  is  black,  the  corresponding
              transparency value is transparent.  Everywhere else, the transparency value is fully opaque.

       -outfile outfile
              If you specify this option, pnmtorle writes the output to this file.  If outfile is - or you don't
              specify -outfile, pnmtorle writes the output to Standard Output.

              Before Netpbm 10.98 (March 2022), this option is just -o.and
                  must be separated from its value by a space, not an equal sign.

EXAMPLES

          pnmtorle -verbose file.ppm -outfile=file.rle

       While running in verbose mode, convert file.ppm to RLE format and store resulting data in file.rle.

          pnmtorle -header file.pgm

       Dump the header information of the Netpbm file called file.pgm.
