Description
- Inverts the values of the pixels. This function is equivalent to mt_lut("255 x -"), but faster.
- mt_invert (clip, int "Y", int "U", int"V", string "chroma", int "offX", int "offY", int "w" int "h")
- clip =
- Input clip.
- clip =
- int Y = 3
- int U = 1
- int V = 1
- These three values describe the actual processing mode that is to be used on each plane / channel. Here is how the modes are coded :
- x = -255...0 : all the pixels of the plane will be set to -x.
- x = 1 : the plane will not be processed. That means the content of the plane after the filter is pure garbage.
- x = 2 : the plane of the first input clip will be copied.
- x = 3 : the plane will be processed with the processing the filter is designed to do.
- These three values describe the actual processing mode that is to be used on each plane / channel. Here is how the modes are coded :
- int Y = 3
- string chroma = ""
- When defined, the value contained in this string will overwrite the u & v processing modes.
- This is a nice addition proposed by mg262 that makes the filter more user friendly. Allowed values for chroma are:
- "process" : set u = v = 3.
- "copy" or "copy first" : set u = v = 2.
- "xxx", where xxx is a number : set u = v = -xxx.
- string chroma = ""
- int offX = 0
- int offY = 0
- "offX" and "offY" are the top left coordinates of the box where the actual processing shall occur. Everything outside that box will be garbage.
- int offX = 0
- int w = -1
- int h = -1
- w and h are the width and height of the processed box. -1 means that the box extends to the lower right corner of the video. That also means that default settings are meant to process the whole picture.
- int w = -1
