    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.
