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

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