Introduction

Scales luminosity values in the source image, similar to VirtualDub's 'levels' filter. This is useful to scale ITU-R601 video (which limits luma to 16-253) back to the full 0-255 range.

Parameters

Default values are shown in [green] in square brackets.

input input luma range (0-255 - 0-255) [0-255]

gamma input luma gamma (0.5-3.5) [1.000000]

output output luma range (0-255 - 0-255) [0-255]
