1 .TH BLIND-SET-SATURATION 1 blind 2 .SH NAME 3 blind-set-saturation - Multiply the saturation of a video 4 .SH SYNOPSIS 5 .B blind-set-saturation 6 [-w] 7 .I saturation-stream 8 .SH DESCRIPTION 9 .B blind-set-saturation 10 reads a video from stdin and a mask video from 11 .IR saturation-stream . 12 The video is printed to stdout, with the saturation 13 of each pixel multiplied by the product of the 14 luminosity and the alpha value of the corresponding 15 pixel and frame in the mask video. 16 .P 17 If stdin is longer than 18 .IR saturation-stream , 19 the remainder of stdin is printed without any changes. 20 If stdin is shorter than 21 .IR saturation-stream , 22 the remainder of 23 .I saturation-stream 24 is ignored but may be partially read. 25 .SH OPTIONS 26 .TP 27 .B -w 28 Instead of using CIE Standard Illuminant D65 as the 29 whitepoint, use the X and Z from each pixel in 30 .I saturation-stream 31 for the whitepoint. 32 .SH SEE ALSO 33 .BR blind (7), 34 .BR blind-single-colour (1), 35 .BR blind-arithm (1), 36 .BR blind-set-alpha (1), 37 .BR blind-set-luma (1), 38 .BR blind-invert-luma (1) 39 .SH AUTHORS 40 Mattias Andrée 41 .RI < maandree@kth.se >
