ImGearRasterProcessing.InvertContrast(page, mode, channels)
public static void InvertContrast( 
   ImGearRasterPage page,
   ImGearContrastModes mode,
   ImGearChannelRange channels
)
public: static void InvertContrast( 
   ImGearRasterPage* page,
   ImGearContrastModes mode,
   ImGearChannelRange channels
) 
public:
static void InvertContrast( 
   ImGearRasterPage^ page,
   ImGearContrastModes mode,
   ImGearChannelRange channels
) 

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.
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.
