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 in‐
       put 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	 In‐
       put.

       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 ), pn‐
       mtorle 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.  Every‐
	      where 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.
