.TH BLIND-COLOUR-CIEXYZ 1 blind
.SH NAME
blind-colour-ciexyz - Convert CIE XYZ for use with blind-single-colour(1)
.SH SYNOPSIS
.B blind-colour-ciexyz
[-%
.IR format ]
.RI ( X
.I Y
.I Z
|
.IR Y )
.SH DESCRIPTION
.B blind-colour-ciexyz
prints the given input as is. If
.BR blind-single-colour (1)
is modified in the future to use another colour model
than CIE XYZ,
.B blind-colour-ciexyz
will be modified to convert the values to
that colour model. If only
.I Y
is specified, the colour will be CIE Standard Illuminant D65-grey
with a luminosity of
.IR Y .
.SH OPTIONS
.TP
.BR -% \ \fIformat\fP
Selects in what format parameters are printed.
.I format
may include the prefix
.B +
that specified that non-negative values should be prefixed with a
.BR + .
After any prefix, there may be a positive number specifying
the percision of the output, optionally followed by either of
the letters
.BR a ,
.BR e ,
.BR f ,
other
.B g
(other their synonymous uppercases),
at most once, with the same semantics as in
.BR printf (3).
.B f
is used if this letter is omitted.
If ommited,
.B 25f
is used unless all three of
.IR X ,
.IR Y ,
and
.I Z
is specified, in which case the parameters are
printed as-is. This default is selected for ease
of interoperability with other software, however,
.B a
is recommeded to improve performance and remove
truncation error.
