1 .TH BLIND-SET-LUMA 1 blind
2 .SH NAME
3 blind-set-luma - Multiply the luminosity of a video
4 .SH SYNOPSIS
5 .B blind-set-luma
6 .I luma-stream
7 .SH DESCRIPTION
8 .B blind-set-luma
9 reads a video from stdin and a mask video from
10 .IR luma-stream .
11 The video is printed to stdout, with the luminosity
12 of each pixel multiplied by the product of the
13 luminosity and the alpha value of the corresponding
14 pixel and frame in the mask video.
15 .P
16 If stdin is longer than
17 .IR luma-stream ,
18 the remainder of stdin is printed without any changes.
19 If stdin is shorter than
20 .IR luma-stream ,
21 the remainder of
22 .I luma-stream
23 is ignored but may be partially read.
24 .SH NOTES
25 In most cases, this is not what you want to use, instead
26 you probably want to use
27 .BR blind-arithm (1)
28 to multiple the X, Y and Z values on one value. This
29 produces the same affect as reducing the intensity of
30 the light sources, which is not what
31 .B blind-set-luma
32 does.
