psign - produce a RADIANCE picture from text.
psign [ options ] [ text ]
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).
- Text reads to the right (default).
- Text reads upwards.
- Text reads to the left (upside down).
- 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 nonzero,
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
To put a big "Hi!" on the terminal:
- -f fontfile
Load the font from fontfile. The default font is
psign -h 22 -a 1 -cb 0 0 0 -cf 1 1 1 Hi\! | ttyimage
- path to search for font files
The entire bitmap is stored in memory, which can be a
problem for large and/or high-resolution signs.
