            3 blind-colour-srgb - Convert sRGB for use with blind-single-colour(1) and blind-colour-matrix(1)

           14 .SH DESCRIPTION
           15 .B blind-colour-srgb
           16 converts the sRGB colour with the specified
           17 .IR red ,
           18 .IR green ,
           19 and
           20 .I blue
           21 values to CIE XYZ and prints the result to stdout
           22 in plain text, such that it can be used with
           23 .BR blind-single-colour (1).
           24 If
           25 .BR blind-single-colour (1)
           26 is modified in the future to use another colour
           27 model than CIE XYZ,
           28 .B blind-colour-srgb
           29 will be modified to convert the values into
           30 that colour model.

           32 .IR red ,
           33 .IR green ,
           34 and
           35 .I blue
           36 may be floating-point values and may be negative
           37 or beyond the maximum value encodable in an
           38 unsigned integer with
           39 .I depth
           40 bits.
           41 .SH OPTIONS
           42 .TP
           43 .BR -% \ \fIformat\fP
           44 Selects in what format parameters are printed.
           45 .I format
           46 may include the prefix
           47 .B +
           48 that specified that non-negative values should be prefixed with a
           49 .BR + .
           50 After any prefix, there may be a positive number specifying
           51 the percision of the output, optionally followed by either of
           52 the letters
           53 .BR a ,
           54 .BR e ,
           55 .BR f ,
           56 other
           57 .B g
           58 (other their synonymous uppercases),
           59 at most once, with the same semantics as in
           60 .BR printf (3).
           61 .B f
           62 is used if this letter is omitted.
           63 
           64 If ommited,
           65 .B 25f
           66 is used. This default is selected for ease of
           67 interoperability with other software, however,
           68 .B a
           69 is recommeded to improve performance and remove
           70 truncation error.
           71 .TP
           72 .BR -d " "\fIdepth\fP
           73 If all three parameters are
           74 .RI 2^ depth -1,
           75 the colour is 100 %. (default: 8)
           76 .TP
           77 .BR -l
           78 The values are encoded linearly instead of with
           79 the sRGB transfer function.
