# Deflate/Inflate

std.Deflate(vnode clip[, int[] planes=[0, 1, 2], float threshold])

  Replaces each pixel with the average of the eight pixels in its 3x3 neighbourhood, but only if that average is less than the center pixel.

  clip

    Clip to process. It must have integer sample type and bit depth between 8 and 16, or float sample type and bit depth of 32. If there are any frames with other formats, an error will be returned.

  planes

    Specifies which planes will be processed. Any unprocessed planes will be simply copied.

  threshold

    Allows to limit how much pixels are changed. Output pixels will not become less than `input - threshold`. The default is no limit.

std.Inflate(vnode clip[, int[] planes=[0, 1, 2], int threshold=65535])

  Replaces each pixel with the average of the eight pixels in its 3x3 neighbourhood, but only if that average is greater than the center pixel.

  clip

    Clip to process. It must have integer sample type and bit depth between 8 and 16, or float sample type and bit depth of 32. If there are any frames with other formats, an error will be returned.

  planes

    Specifies which planes will be processed. Any unprocessed planes will be simply copied.

  threshold

    Allows to limit how much pixels are changed. Output pixels will not become greater than `input + threshold`. The default is no limit.
