Constructors

GPULevelsFilter()

Photoshop-like levels adjustment. The minimum, middle, maximum, minOutput and maxOutput parameters are floats in the range 0, 1. If you have parameters from Photoshop in the range 0, 255 you must first convert them to be 0, 1. The gamma/mid parameter is a float >= 0. This matches the value from Photoshop. If you want to apply levels to RGB as well as individual channels you need to use this filter twice - first for the individual channels and then for all channels.
