NAME

       psign - produce a RADIANCE picture from text.

SYNOPSIS

       psign [ options ] [ text ]

DESCRIPTION

       Psign  produces  a  RADIANCE  picture  of  the  given  text.  The output dimensions are determined by the
       character height, aspect ratio, number of lines and line  length.   (Also  the  character  size  if  text
       squeezing is used.)  If no text is given, the standard input is read.

       -cb r g b Set the background color to r g b The default is white (1 1 1).

       -cf r g b Set the foreground color to r g b The default is black (0 0 0).

       -dr       Text reads to the right (default).

       -du       Text reads upwards.

       -dl       Text reads to the left (upside down).

       -dd       Text reads downwards.

       -h cheight
                 Set the character height to cheight.  The default is 32 pixels.

       -a aspect Set the character aspect ratio (height/width) to aspect.  The default value is 1.67.

       -x xsize  Set  the  horizontal  image  size  to  xsize.   Use  with  -y option (below) in place of the -h
                 specification to control output image size directly.  If the character aspect ratio (-a option,
                 above)  is  non-zero,  then  one  of  the  specified x or y output dimensions may be reduced to
                 maintain this ratio.  If direction is right (-dr) or left (-dl), then it is  not  necessary  to
                 give the -y option, since it can be computed from the character height (-h).

       -y ysize  Set  the vertical image size to ysize.  Use with the -x option (described above).  If direction
                 is up (-du) or down (-dd), then it is not necessary to give the -x  option,  since  it  can  be
                 computed from the character height (-h).

       -s spacing
                 Set  the  intercharacter  spacing to spacing.  The magnitude of this value is multiplied by the
                 character height over the aspect ratio  (ie.  the  character  width)  to  compute  the  desired
                 distance  between  characters  in  the  output.   The  sign of the value, positive or negative,
                 determines how this ideal spacing is used in the actual placement of characters.  If spacing is
                 positive,  then  the  overall  width  of the line will not be affected, nor will indentation of
                 textual elements.  Thus, the text format will be mostly unaffected.  However,  spacing  between
                 characters  will  reflect  their  relative  size  for a more natural appearance.  If spacing is
                 negative, characters will be squeezed together to meet the spacing critereon, regardless of how
                 it  might  affect  the  format  of the output.  The default value for spacing is zero, which is
                 interpreted as uniformly spaced characters.

       -f fontfile
                 Load the font from fontfile.  The default font is helvet.fnt

EXAMPLE

       To put a big "Hi!" on the terminal:

         psign -h 22 -a 1 -cb 0 0 0 -cf 1 1 1 Hi\! | ttyimage

ENVIRONMENT

       RAYPATH        path to search for font files

BUGS

       The entire bitmap is stored in memory, which can be a problem for large and/or high-resolution signs.
