|
7 .SH DESCRIPTION |
|
8 .B blind-matrix-orthoproject |
|
9 creates an affine 2D-transformation matrix for |
|
10 othogonal projection. The parameters for the |
|
11 matrix is read in stdin in format of a blind video, |
|
12 one matrix per frame in stdin created and printed |
|
13 to stdout in format of a blind video. |
|
14 .P |
|
15 Each frame in stdin shall contain exactly 2 pixels, |
|
16 the first pixel holds the x-value of the vector the |
|
17 image is projected along, the second pixel holds the |
|
18 y-value of this vector. |
|
19 .P |
|
20 The luma (encoding in the Y-channel, the second |
|
21 channel) multiplied by the alpha (the fourth channel) |
|
22 of the input pixels are used as the values. Each |
|
23 values in the resulting matrices are stored |
|
24 in all channels. |
|
25 .SH OPTIONS |
|
26 .TP |
|
27 .B -c |
|
28 Create different matrices for each channel. Use |
|
29 values from each channel in stdin to create |
|
30 matrices whose values are stored in the same |
|
31 channels in stdout. |
