       rlehdr - Prints the header of an RLE file

       rlehdr [ -b ] [ -ccomment-names ] [ -d ] [ -m ] [ -v ] [ files ...  ]

       This  program  prints  the  header  of RLE(5) files in a human readable
       form.  If the optional files argument is not supplied,  input  is  read
       from standard input.

       -b     Print  the  information in a "brief" one-line form.  The form of
	      the output line is
	      name: [l,b]+[xs,ys]xnc+A, BG=color, map=NxL, (C)
	      Where [l,b] is the position of  the  lower-left  corner  of  the
	      image,  [xs,ys]  is  the	size of the image in pixels, nc is the
	      number of channels saved, +A is present if an alpha  channel  is
	      saved.   BG=  or OV= indicate that a background color was saved;
	      OV= means that the existing background is	 not  cleared  to  the
	      background  color	 before the image is read (this was used for a
	      cheap form of  compositing,  but	is  basically  obsolete	 now).
	      color  is	 the  saved  background color.	The map= entry will be
	      present only if a color map was saved; N is the number of	 chan‐
	      nels  in	the color map and L is the length of the map.  Finally
	      (C) is appended if there are comments present.

       -c comment-names
	      If a comment identified by any of the words in  the  comma-sepa‐
	      rated list comment-names is present in the input file, its first
	      line will be printed.  Each name is tried, in turn, and only the
	      first  match is printed.	If no match is found, but comments are
	      present, (C) will be printed.  The -c flag implies -b.

       -d     Dump a very verbose version of the image contents as text to the
	      standard error output stream.

       -m     Print out the color map information.  -v Prints the raster tool‐
	      kit version and patch level.  No input files will	 be  processed
	      if this option is given.

       rlehdr image.rle
	      Print  the  header  information  for  all	 images	 in  the  file

       rlehdr -m image.rle
	      Also print the color map contents, if one is present.

       rlehdr -b *.rle
	      Print one line summaries of all the images in the directory.

       rlehdr -c title,TITLE *.rle
	      Print one line summaries of all the images, and print the	 title
	      of any that have a title comment.

       urt(1), RLE(5).
