	2 .SH NAME
	3 blind-colour-srgb - Convert sRGB for use with blind-single-colour(1) and…
	4 .SH SYNOPSIS
	5 .B blind-colour-srgb
	6 [-%
	7 .IR format ]
	8 [-d
	9 .IR depth ]
	10 [-l]
	11 .I red
	12 .I green
	13 .I blue
	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.
	31 .P
	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.
