This program magnifies (zooms) an _R_L_E(5) file by a float
ing point factor. Each pixel in the original image
becomes a block of pixels in the output image. If no _y_-
_f_a_c_t_o_r is specified, then the image will be magnified by
_f_a_c_t_o_r equally in both directions. If _y_-_f_a_c_t_o_r is given,
then each input pixel becomes a block of _f_a_c_t_o_r × _y_-_f_a_c_t_o_r
pixels in the output. If _f_a_c_t_o_r or _y_-_f_a_c_t_o_r is less than
1.0, pixels will be dropped from the image. There is no
pixel blending performed. Input is taken from _i_n_f_i_l_e, or
from the standard input if not specified. The magnified
image is written to the standard output, or _o_u_t_f_i_l_e_, if
specified.
You should use _r_l_e_z_o_o_m over _f_a_n_t(1) if you just want a
quick magnification of an image with the pixel boundaries
showing. It is significantly faster than _f_a_n_t because it
does no arithmetic on the pixel values. If you need
blending between pixels in the magnified image, then _f_a_n_t
is the correct program to use. Use _r_l_e_z_o_o_m _-_f _f_a_c_t_o_r _y_-
_f_a_c_t_o_r to produce an image the same size as _f_a_n_t _-_p _0 _0 _-_s
_f_a_c_t_o_r _y_-_f_a_c_t_o_r for previewing purposes.
Note: due to the way that _s_c_a_n_a_r_g_s(3) parses the arguments
from the command line, if the name of _i_n_f_i_l_e is a number,
and it is in the current directory, you should prefix it
with "./" so that it will not be confused with _f_a_c_t_o_r or
_y_-_f_a_c_t_o_r.
