       ImGearRasterPage page,
       ImGearContrastModes mode,
       ImGearChannelRange channels
    )
    public: static void StretchContrast(

       ImGearContrastModes mode,
       ImGearChannelRange channels
    ) 
    public:
    static void StretchContrast( 
       ImGearRasterPage^ page,
       ImGearContrastModes mode,
       ImGearChannelRange channels
    ) 

    Parameters

    page
    Image to process.
    mode
    One of the contrast processing modes: ImGearContrastModes.PALETTE, ImGearContrastModes.PIXEL, ImGearContrastModes.AUTO.
    channels
    Channel range to process.
    Remarks
    Can be applied only to raster pages with standard (non Run-Ends) DIB.

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

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