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.
Remarks
Processes specified range of channels.

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

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