       rletoascii - Print an RLE image as ASCII chars.

       rletoascii [ -S asciistr ] [ -r ] [ -o outfile ] [ infile ]

       Rletoascii  reads  a  file  in  RLE(5) format, converts it to black and
       white, then dumps it as ASCII characters.  The 0 to 255 range of	 pixel
       values in the image is scaled to the length of asciistr and a the char‐
       acter at that position in the string is printed for each pixel.	 Input
       will  be read from infile if specified, from standard input, otherwise.
       Output dumps to standard output, or outfile, if specified.

       Usually, the input will need to be resized by fant(1) or rlezoom(1)  to
       make  it	 small	enough	to  fit	 on the screen and to adjust the pixel
       aspect ratio to the "character aspect ratio" of the terminal.   To  get
       it "right side up", use rleflip(1) with the -v option.  Finally, it may
       be helpful to maximize the dynamic range with rlespiff(1).

       -S asciistr
	      Specifies the range of ascii  characters	for  conversion.   The
	      default  string  (@BR*#$PX0woIcv:+!~".,  )  was designed to look
	      good with the X 6x13 font.

       -r     Reverse video.  This causes the 0 to 255 range to be  mapped  to
	      the reverse of the ascii string.

       fant(1), rleflip(1), rlespiff(1), rlezoom(1), urt(1), RLE(5).

       Rod G. Bogart, University of Michigan.

       Could be rewritten to use overprinting for output to a real printer.
