28 .SH DESCRIPTION
29 .B blind-primary-key
30 reads a video from stdin and replaces a primary
31 with transparency and prints the resulting video
32 to stdout.
33 .B blind-primary-key
34 internally converts colour space to the one
35 with the primaries whose CIE XYZ values are
36 .RI ( X1
37 .I Y1
38 .IR Z1 ),
39 .RI ( X2
40 .I Y2
41 .IR Z2 ),
42 and
43 .RI ( X3
44 .I Y3
45 .IR Z3 )
46 and whose white point is the colour whose
47 CIE XYZ values are
48 .RI ( white-X
49 .I white-Y
50 .IR white-Z ),
51 and replaces the first primary with transparency.
52 If the white point is not specified,
53 CIE Standard Illuminant D65 is used.
54 .P
55 If the colour space is specified, no conversion
56 is done internally.
57 .SH OPTIONS
