- _R_l_e_t_o_a_s_c_i_i reads a file in _R_L_E(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 _a_s_c_i_i_s_t_r and a the character at that position in
- the string is printed for each pixel. Input will be read
- from _i_n_f_i_l_e if specified, from standard input, otherwise.
- Output dumps to standard output, or _o_u_t_f_i_l_e, if specified.
-
- Usually, the input will need to be resized by _f_a_n_t(1) or
- _r_l_e_z_o_o_m(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
- _r_l_e_f_l_i_p(1) with the ----vvvv option. Finally, it may be helpful
- to maximize the dynamic range with _r_l_e_s_p_i_f_f(1).

- ----SSSS _a_s_c_i_i_s_t_r
- Specifies the range of ascii characters for conversion.
- The default string (@@@@BBBBRRRR****####$$$$PPPPXXXX0000wwwwooooIIIIccccvvvv::::++++!!!!~~~~""""....,,,, ) was
- designed to look good with the X 6x13 font.
-
- ----rrrr Reverse video. This causes the 0 to 255 range to be
- mapped to the reverse of the ascii string.
