FixLuminance(clip clip, int intercept, int slope)
- int intercept = (required)
- Line at which to start correction.
- int slope = (required)
- Slope of correction function. The top of the picture is made darker by 1 (on a 0-255 scale) every slope lines.
- Maximum darkening (at top line) = intercept / slope
The purpose of this filter is to progressively darken the top of the image; for example, to compensate for certain VCRs which make the top of each frame brighter than the bottom. This filter works only with YUY2 input.
