Parameters

page

Image to invert contrast.

mode

One of the contrast processing modes: ImGearContrastModes.PALETTE, ImGearContrastModes.PIXEL, ImGearContrastModes.AUTO.

channels

Channel range to invert contrast.

options

Contrast options. See ImGearContrastOptions class.

If Mode is equal to ImGearContrastModes.PALETTE, DIB must have a palette.

Use ImGearRasterProcessingVerifier.CanApplyInvertContrast method to check whether the operation can be performed.
