      1 .TH BLIND-COLOUR-CIEXYZ 1 blind
      2 .SH NAME
      3 blind-colour-ciexyz - Convert CIE XYZ for use with blind-single-colour(1)
      4 .SH SYNOPSIS
      5 .B blind-colour-ciexyz
      6 [-%
      7 .IR format ]
      8 .RI ( X
      9 .I Y
     10 .I Z
     11 |
     12 .IR Y )
     13 .SH DESCRIPTION
     14 .B blind-colour-ciexyz
     15 prints the given input as is. If
     16 .BR blind-single-colour (1)
     17 is modified in the future to use another colour model
     18 than CIE XYZ,
     19 .B blind-colour-ciexyz
     20 will be modified to convert the values to
     21 that colour model. If only
     22 .I Y
     23 is specified, the colour will be CIE Standard Illuminant D65-grey
     24 with a luminosity of
     25 .IR Y .
     26 .SH OPTIONS
     27 .TP
     28 .BR -% \ \fIformat\fP
     29 Selects in what format parameters are printed.
     30 .I format
     31 may include the prefix
     32 .B +
     33 that specified that non-negative values should be prefixed with a
     34 .BR + .
     35 After any prefix, there may be a positive number specifying
     36 the percision of the output, optionally followed by either of
     37 the letters
     38 .BR a ,
     39 .BR e ,
     40 .BR f ,
     41 other
     42 .B g
     43 (other their synonymous uppercases),
     44 at most once, with the same semantics as in
     45 .BR printf (3).
     46 .B f
     47 is used if this letter is omitted.
     48 
     49 If ommited,
     50 .B 25f
     51 is used unless all three of
     52 .IR X ,
     53 .IR Y ,
     54 and
     55 .I Z
     56 is specified, in which case the parameters are
     57 printed as-is. This default is selected for ease
     58 of interoperability with other software, however,
     59 .B a
     60 is recommeded to improve performance and remove
     61 truncation error.
